Btw, I wonder why it is yet worse to its predecessor, i.e., the V1? More pixels but worse image quality?! :-o

Six models of Pentax DSLRs are included. The results can also be compared to other camera models of other makes as well.
I think the above is of high risk. Do only when you clearly know what you are doing and try it at your OWN RISK!
Now, the new SR lens is fully supported.
So, what is that btw? "IF"? :-o

(Above: Pentax AF200S put onto the Q - Click to Enlarge.)
Everything has got so unbalanced when the something is attached on the Q. But in order to get rid of the annoying P-TTL of the Q, an external auto flash unit with built-in flash exposure meter and control is required! ;-D
Now, there is no more annoying pre-flash and picture taking is just instantaneous, i.e., without any delay just because of the pre-flash. The exposure is more consistent and accurate, too. The same applies when the same "obsolete" thing is attached on my K-5! Amazing enough?
Look at the above gear photo at the right, you can see a working combination of the settings in both the camera and on the flash, for instance.
But there is a bug of the Q's firmware actually (I have updated to the latest version already). That is, the built-in flash is still firing when an external flash gun is attached. So, I've tried to set the custom function No. 10 of "not discharge flash" when the "flash is retracted". However, by doing so, the external flash will NOT be fired then!? So, what I have to do is to set "no flash" for the built-in flash but with the custom function No. 10 set at default (i.e., discharge flash when retracted) then it finally works! :-o
Even more unfortunately, the behaviour of the Q with the later generation of the Pentax auto-focus dedicated flash units (which are with four pins at the hot-shoe) is even more helpless. It is because the external flash will NOT be discharged even when the built-in flash function is set at "no flash". So, the tiny little built-in flash must be discharged at the same time with the large external flash. The worst thing is that the external flash has to wait the little P-TTL flash to complete its pre-flash before both can fire altogether! Otherwise, in all other circumstances, both flash units are turned off no matter how the user sets the Q and his original *Pentax* flash! >:-(
Btw, for a list of downloadable user manuals of those old and new Pentax flash units, the following official link can be visited:-
Last but not least, as for the flash trigger voltage of my AF200S, it is measured to be +2 Volt with flesh Alkaline batteries inserted. It is also worth noting that it is mentioned in the Pentax Q manual that flash unit with a negative trigger voltage could not be used with the camera. So, mine should be very safe to use! :-)

PENTAX Ricoh imaging incorporated company
Is a full size tinged with a touch of reality? The new product of the Ricoh brand is also due to be put on the market.
PENTAX Ricoh imaging incorporated company development generalization division manager Toshiyuki Kitazawa 72 1978, Asahi Optical Co., Ltd. (that time) entrance into a company.
A camera designing department is assigned.
In charge of the mechanism design of a camera.
He is a development person in charge at Z-1.
2001, the head of the development department Digital LS, in charge of the digital SLR.
In 2006, it will continue up to now through a imaging system operation division division assistant vice president.
It is consistently engaged in camera-related development.
Favorite cameras are K-r, K-5, and PENTAX Q.
Year 2 0 1 3 of seasonal keyword PENTAX Ricoh (description and editorial department)
- it is alike by of a great desire full size, and say that the full-size machine is studied and developed. if it appears, a single lens reflex camera type possibility seems to be high
- moire removal function in camera K-5?s -- a low -- the new product of - Ricoh Brando new product Ricoh Brando who is also studying the technology in which moire is removable within a camera.
- although high definition-ization depended pathless was realized and who is is an appearance.
It may be a different type from GR DIGITAL or GXR.
Seemingly it is a camera which the core Ricoh fan can satisfy.
Is new mount or compatibility of a full size K mount maintenance of a melon?
(Update: I only translate the interview below in full but not for the whole article, please note my translation in bracket and in Italic.)
About what time is the schedule of a full-sized camera, excuse me?
(What is the schedule for a full frame camera?)
Kitazawa: -- it is a full-sized talk -- it is -- suddenly --.
(It's about the full frame camera, so suddenly.)
It is a continuation of the interview of ? last year (smile), and is from the talk of a full size and 645D Miller Les.
(Let's continue our talk about a full frame camera and a mirrorless 645D that we discussed about in the last year's interview.)
Kitazawa: Is it its concentration (smile)?
(We are putting our efforts on these.)
Has development of ? full size started?
(Has the development of full frame begun?)
Kitazawa: Development is already started fundamentally.
Since it is dependent on the circumstances of marketing, it cannot be said whether lends and there is any producing commercially not at all.
An important thing is what PENTAX goes into a full-size market and made.
Clarify the place where NIKON, Canon, and Sony are damaged, and the difference where PENTAX can do it.
What is the place which the visitor expects from us?
It is how to discern the hit thoroughly and to incorporate in the product.
Development takes time. Although are just going to say that he is following the place which should include an interchangeable lens and it becomes empty.
(The development has already begun but the final sales of the product will depend on many factors. It is important for Pentax to determine the marketing position of our product and how it is differentiated from the other existing products by Nikon, Canon and Sony. What are our customers expecting from us? Those are what we are to incorporate into our product. But development takes time and we would follow the trend to make an interchangeable lens full frame.)
Although it was the nuance that Miller Les without a mirror shock of Mr. Kitazawa was better at the last interview although it is ? full-size camera, which direction is considered?
(It was talked about the mirror vibration of reflex and Mr. Kitazawa did prefer mirrorless in the last interview. What direction will be taken for the full frame camera?)
Kitazawa: It is a very difficult question (smile).
Miller Les, the type of a single lens reflex camera, and 2 have appeared in the camera of the APS-C seal by PENTAX Brando now.
If many things are compared, it is sufficient in each and the various visitors' opinion is heard, it is rather used by lightweight as Miller Les.
Are there fairly many the visitors who would like for the single lens reflex camera type with Miller to make photography a hobby, or to create the photograph itself?
The present visitor of ours thinks going [ into such a category ] kana.
There is an uncanny merit that a novel design can also do a ミラーレス camera and only ぶん which naturally does not have Miller can make form thin small.
Furthermore, also at a low price, it can do.
Although it may have been called mirror レスフル size till last year, many things are seen, and it is when.
At the time of た, if a full size says which is individually considered by priority now, it is a way "with a mirror."
It is whether goods have responded to that for which the visitor asks.
Kana which is not easily accepted even if it takes out what suits neither the visitor's user-friendliness, nor a demand, although it is also important to create new value.
As for me, the inside seal thinks suitable kana rather than a large full size of the merit to which Miller Les rather reduces a mirror shock.
(It is a very difficult question. Mirrorless and SLR are actually two kinds of camera products in APS-C which Pentax have. The opinions from our various customers are being heard. People do prefer lightweightedness for mirrorless. As for other customers who like the reflex, they are mostly hobbyists and are more serious to take photographs as creation. The advantages of mirrorless are that it could be made thinner and smaller and at a lower cost as well. For the time being, it is considered that if a full frame camera is made, it should be in the direction of having a mirror. It is just because we are responding to what our customers want. It is also important to create new values of the product such as better user-friendliness. As for myself, I do prefer mirrorless so as to avoid the mirror shock.)
Miller Les and a single lens reflex camera have a merit and a demerit, respectively.
They are a variation of an interchangeable lens, and the difference in user-friendliness as the one.
There are also merits, such as if the single lens reflex camera of a telephoto lens is easier-to-use than Miller Les, a possibility that the conventional lens can be used.
(Mirrorless and single lens reflex do have merits and demerits of their own. Mirrorless is a variant of the reflex but their operations are different. The reflex has the advantage when using a telephoto lens than mirrorless, which is better to use with a standard lens.)
For example, supposing it gives Miller Les, does it do whether it does by new mount by the present K mount, and will also be argued.
If Miller Les is given at any rate, new mount will be used, a back size is shortened with light path length to a slight degree, and also the diameter of mount is made a little larger than K mount, and it is meaningless if it does not aim to make it the light flux of a bright lens arrive easilier etc.
(Well. Suppose it is a mirrorless, we should choose whether to use a new mount or keep the K mount, which is arguable. If an ideal mirrorless system is to be made, a new mount should be used, which should have a shorter back focus register distance but with an increased diameter than the K mount, which will be more meaningful.)
A new single lens reflex camera or Miller Les -- at any rate -- whether mount is temporarily built newly also as a single lens reflex camera by carrying out or the conventional K mount is inherited worry, and it is どころ.
(Is a new mount being built to replace the K mount, no matter for the new reflex or mirrorless camera?)
Kitazawa: It is a large trouble there.
In the case of PENTAX, mount came without changing and was called the demon's compatibility all the time.
The visitor needs to trust PENTAX and that should follow all the time.
(It is the big trouble here. In case Pentax keep the mount, compatibility can be maintained. Our customers need to trust us and we are studying the issue for the time being.)

Via Digicame Info (in Japanese) Via Pentax Fan Club Forum (Taiwan, in Chinese).
The Head of Product Development of Pentax Ricoh, who was first employed by the Asahi Optical Company back to 1978, is interviewed. It is told that a new set of 35mm full frame specifications is being formulated and that new moire removal algorithms are being developed as new in-camera function (which the K-5IIs doesn't have). Besides, a Ricoh brand new camera will come. As for the other PR unrelated stuff, I think the most interesting thing is that Foveon is making a new full frame sensor, as well as a monochrome one.
Good news after all! I am almost sure that I will buy one when it arrives! Keep it up, PR!

1. First of all, here comes the new patent of Nikon's "silicon film", i.e., a digital back for old analogue film cameras, but which is yet a vapourised ware that has never come true, since it was first announced back to 1999.

4. An old YouTube demo on the sturdiness of the Pentax SP coating and how easy it can be cleaned:-
Well, whilst I do agree that the SP is easy to clean and it is very sturdy, I found that it is also a bit more shiny when it is compared to traditional SMC coatings on the front glasses. Thus, more light could be lost and it should be a trade-off after all. :-(

Here is a new guide with additional tips for an enhanced method, on top of the original one:-
The article is in Traditional Chinese, but the pictures are self-explanatory. Each picture of the series represents each step of the whole repair procedures. The new trick is to turn further from the underneath of the motor module, which should be further dismantled, just in case if the screw on the top is locked too tight and cannot be turned. See the two key diagrams for what to turn:-
As for the force applied, the author hints that you should try it by yourself - do not apply excessive force and try different directions, depending on how the SDM motor and the associated gears are locked.
Good luck if you are yet one of the SDM failure victims and still want to try the repair DIY! As for me, I have none of the Pentax SDM lenses, just because the SDM issue has been so infamous but then the service and support of Pentax to deal with the issue usually sucked as widely reported, so that I have been avoiding it as far as possible over these years.

The 645D IR is released today:-
(in Japanese, Excite English Translation Here.)
After all, it is essentially a 645D with the IR-cut filter removed. The production volume is targeted to be in 100 units per year, btw. It is further stated that when an IR-cut filter is added back by mounting onto the front thread of the lens, the 645D can be used again as a normal camera.
Yet another thing that I wonder is why this press and news is posted at the Ricoh website instead of the Pentax one? Did they intend to market the 645D IR as a security camera that took only still pictures? What is the point actually? :-o
Ricoh Introduced FA Line of Lenses and Camera Bodies!
A K-5IIs user complained about his new K-5IIs body had an air leakage problem which is demonstrated in the following YouTube video that he uploaded:-
He hence requested for a replacement unit. After the replacement unit arrived, he did the following comparison test:-
Via: Post @ Pentax Fans Club (Taiwan)
Wow, what a difference and what a QC! Pentax just built and marketed a supposedly sealed-model which is actually not completely sealed! :-o After this incident, I think Pentax should add a toilet paper test in their QC line for what this end-user has done, so as to check if the sealing of their cameras is proper, frankly!
Tuesday, December 11, 2012
Original full samples of the test pictures are available for downloading. EXIF is preserved.
The DxOMark of the K-5IIs has been out.
A quick comparison of the K-5IIs against the K-5II against the K-5 is as follows:-
Now, we can see a major pitfall of the DxOMark here, that is, it actually never measured any actual resolution of any camera! What they took into account is only the pixel count of the cameras as specified. It is therefore whilst the marks of the cameras under test are all the same, in this case it is the K-5s', but in reality the Image Quality of them may be different! But then what is the meaning of this IQ benchmark then?! :-o
Saturday, December 08, 2012
1. Pentax Q with 01 8.5mm prime lens, effective 135 focal ~47mm; NEX-3 with E 30mm Macro lens, effective 135 focal ~46mm.
2. Both cameras set in Av mode for best performing f-stop so as to avoid diffraction while stopped down for just more than 1 stop, namely, Pentax Q at f/2.8 and the NEX at f/5.6. Multi-point single autofocus set for both cameras.
3. 2 second timer was used for both cameras, each of which was mounted on a sturdy tripod during shooting.
4. Auto White Balance and colour mode of Pentax Q was Portrait (all in default settings) and that of the NEX was Landscape (with Contrast -1, others at defaults).
5. NR settings of both cameras were left at their factory defaults.
Okay, let's go! Note the captions of the image files for what are them. EXIF is also preserved:-
Please feel free to tell us what you've measurbated and found! Btw, I found it is really amazing for the PQ of this little toy which is also called as P-Q! ;-D
Tuesday, December 04, 2012
Finally, I've got it! At (US)$350, these four things are bundled!
So far, at this price, I love my Q. It is just a lovely little DC, with very good image quality for a compact and is really very easy to carry anywhere and is surely very easy and a fun to use! And, the build quality is really impressive, it feels far more solid than my K-5 when put in my hands! :-o
Here are some quick samples, made directly out of the Q, the EXIF is preserved. I am actually impressed with that ISO 1000 shot, for the low noise and image details retained:-
Besides, the colour and exposure accuracy of this cam is not bad. More samples would follow later..

For details, see the latest news reports by Reuters, PR-Inside.com and Business Wire and etc.
The following official web-page shows a summary of all the new products, at the Pentax Europe website, for instance:-
Btw, it seems that those guys at Pentax are loving the name of i10 and HD very much, so that they have to use it over and over again, even though actually they are now two different companies that sell completely different products, but yet with the same name, which they share as the "same" make of their products, and the "same" website domains as well! :-o
Saturday, December 01, 2012
The above is the official list of all the discontinued Pentax camera models at the Japanese Pentax homepage. The K-01 and Q aren't been there yet but this does not necessary mean that so they are still in production. And, in the list we can see the VS20, which is a product that has never really appeared in the streets before it is discontinued. Really sad and what a pity! :-(
Btw, the file name of the high resolution product image which is linked in the above page is "t-da18-270mm_F35-63ed_sdm.jpg". So, what does the "t" letter mean and represent? Tamron?!
After all, RP is just so honest! Do they really need to tell this again even though all people already knew! >:-o
As for the price, whilst it is said to be "opened". I guess this lens will not be cheap, with reference to the price of the original Tamron version that is already on sales in the market for quite some time now.

It is now available at the official Japanese Pentax Ricoh online shop:-

(Above: My MZ-30 with my FA 43 Limited)
The week before, when I tried to use my MZ-30 for shooting film, the light meter first went nuts and then the mirror locked up after pressing the shutter and it did never come down again anymore no matter how!
I used nearly new Panasonic CR2 lithium batteries and its expiry date is in 2020, which worked completely flawlessly when they were put into my MZ-S. Really too bad.. :-(
And, my SFX did die twice like that, for exactly with the same symptom and for what happened. What an unfortunate "coincidence"! >_<

One more year has elapsed and today is the 6th anniversary of my Blog!
I have been a Pentax user since 1988 and up till now I have been using the Pentax K-mount system for over twenty-four years (before that I was using a Canon). And the amount of time which I have contributed to the Pentax community via my this Blog is only a quarter of my whole time with Pentax.
During these six years, I have seen the rises and falls of some Pentax blogs, which the owners of the blogs have stopped updated theirs for some reasons, no matter how, but a common reason was that they actually switched. Fortunately, I am still here to "serve" the community. I am glad that Pentax is still alive and yet I am supporting the brand as long as Pentax is at least producing something that I am finding them useful and with some values and meanings to me.
As for the "popularity" and amount of traffic to my Blog, this is what the Statcounter shows, for the Yearly roundup:-
So, 2012 is the year with most visits (for more than one million) since the birth and launch of my Blog. I think the above recorded numbers are accurate as the Google data for Blogger generally tallies with the above, but with even a bit more of the traffic counts. I am not completely sure if it is because of that more people are interested in the Pentax gear or that I have gained more and more readership amongst the Pentax community. But from the referral (links) reports that I have been inspecting, I think the latter should be true.
Anyway, I still hope that Pentax will market a FF K-mount DSLR in the next year, which is what I have been waiting for ten years now, since my first *ist D! There is still hope, right? :-)

Two weeks ago, Blog reader "daedbird" first reported that the video recording quality of his K-01 was greatly degraded when the SR was turned on against off. When the SR was activated, obvious rolling shutter effect was seen.
Yesterday, another Blog reader "kadajawi" has responded and writes that it is all about the electronic SR that is actually adopted for all those Prime M Pentax cameras for the Movie mode, K-30 and K-01 inclusive. On the other hand, the K-5 cameras which have the Prime II processor use the hardware SR, i.e., sensor movement, to compensate for the hand shake during video recording.
To verify this, I have checked the online user manuals of the K-30, K-01, K-5 and the K-5II/s as well. It is found that the SR for Movie is defaulted to On for the K-30 and K-01 whilst for the K-5 and K-5II, it is default to be Off instead. So, the supposition of "kadajawi" seems to be true for that "coincidence". Nonetheless, no Pentax manual has ever told anything about the actual SR method and the working principle of it, which yet looks like top secret of their cameras but which we users should actually know about.
Yes, the electronic SR is noiseless but it sacrifices video quality. The mechanical SR is noisy but this problem can be overcome by mounting an external microphone with a shock mount. So, all in all, this is not a real problem and better sound reception quality is gained with the use of an external microphone (and with stereo sound recording possibility too). In practice, my own experience that is the body sensor SR is very useful for handheld video recording to stabilise the video and this feature is still useful when monopod is used.
After all, I think Pentax should give all the Prime M users an option, in the firmware and user menu, for the choice of the SR method via electronic (software) mean or yet the conventional mechanical one, then that would be the best.

A Not-so-common K-30/K-5/K-01 Comparison of Mine

This Pentax user/fan has many of the latest Pentax bodies and more importantly many excellent K-mount lenses including the original Pentax ones and those Carl Zeiss ZK lenses built by Cosina. Have a look on those samples that are grouped by lens or camera model and you will not be disappointed. Full samples are available for some.
In addition, he also writes a review for each of his gear for its pros and cons and an overall mark of his is given. Go find out yourself for which lens received a full mark of 120 according to his marking system.
A Japanese Pentax Gear Photo Page
Zeiss Stopped Production of (Z)K-mount Lenses
All Voigtlander K-A Mount Lenses are Discontinued
Same overall score as the K-5, but with slightly better sub-scores. All in all, no big differences.
Still, I am quite sceptical to those DxOMark results. As it is stated, the K-5 and K-5II is one mark ahead of the Canon 5D MkIII, which I also have. I have been using both cameras extensively for months already up till now. In practice, I yet found the 5D3 is better in IQ than the K-5 in almost every aspect, except the DR, which the DxOMark test result for this should be true. Btw, here are two old head-to-head tests of mine between the two cameras. Go figure out yourself!
1. My 5D3 Vs K-5 Realworld Shootout
2. 5D3 Vs K-5 ISO Shootout (100 to 25600)
In particular, the red colour smear of the K-5 images is so obvious and its sensor and image engine combo is just unable to handle these situations well, whilst the 5D3 performs far better in similar cases. The 5D3 also wins in more detailed and accurate colour rendition and in resolution, too, of course.

See the comparison below, from -4 to +4, for the Sharpness, Fine Sharpness and Extra Sharpness, total 27 different settings:-
Of course, if you're interested, you can read also the rest of the review and inspect the posted ISO shootout crops series against K-5 as well as those real-world samples.

The new patent is a 24-100mm 135 equivalent zoom lens on a 1/1.7" sensor.

Just feel free to drag on the crop selection window and measurbate endlessly by yourself, for different parts of the sample pictures of different cameras which you want to compare with.
Obviously, false colours and moires are major issues of the IIs' sample. Btw, the per pixel sharpness of the IIs is better than the II but it doesn't hold true for the per pixel smoothness, at the same time. So, everything is just a compromise afterall, between the II and IIs, with and without an AA filter.
As for other cameras which are having 50% more pixel counts, e.g., the 5D3 and D600 Full Frame bodies, of course we can get the best of both worlds, i.e., higher resolution without any false colours and moires!

A working method with full instructions can be found here:-
For the files that are mentioned and needed, they can be downloaded here directly, if you just don't know how to compile them yourself:-
This may be useful for those who need to do astro-photography in a continuous way without any interruption for longer time exposure per shot.
As for the latest Pentax DSLR models after K-r (i.e., K-r, K-5, K-30, K-5II and IIs) that cannot open the Debug mode by the above method, you can try to use the PK Tether software and then load the SYSPARAM.TXT file at the SD Card Root to see if it works or not! And please let us know about your result if you really try!
Btw, today, I've just come across these photos taken by a Japanese with his EOS 60D and 10-17mm wide angle lens combo. They are quite nice, look:-
N.B. Pentax DSLRs using the Samsung sensors (i.e., K20D and K-7) do not have any option to turn off the DFS (Dark Frame Subtraction) whereas other Pentax DSLRs using the Sony sensors can have the option to turn off DFS for exposure that is not longer than 30 seconds, otherwise DFS is forced to be turned on again.
K-5 and K-r Debug Mode Unleashed, Finally!
Successfully Open the Debug Mode of My K-r! :-)

Look at these pictures:-
And a YouTube video to explain the setup, procedures and techniques to take these wonderful shots:-
The lens was reversed with adaptor and with extension tube plus flash.

A Pentaxian at Taiwan received his new K-5IIs and has unboxed it and done some quick side-by-side image comparisons against his old K-5:-
Well, whilst the K-5IIs images are sharper, they are cooler in tone, which was the thing I found last time. Also, a "sharper" image doesn't necessary mean that it is smoother and looks natural, just go find out yourself! :-)
(in Russian, Google English Translation Here.)
(in Russian, Google English Translation Here.)
I think both tests are well carried out. As for the test results, it is shown that the K-5IIs does work better, for both the details contained in the images and the low light AF performance.

1. Supports Only Original Pentax Lenses!
I always suggest Pentax users buy only original Pentax lenses. It is because if you want to use Sigma or Tamron or even Tokina, there is no reason to stay with Pentax, as those 3rd party lenses are rather limited in K-mount in both models and availability. So, why to do so, to get the worst of both worlds?!
Now, more and more compatibility issues have been reported with the latest Pentax bodies and/or firmware with those 3rd party lenses, here is a latest user report about (in Traditional Chinese) that the K-01 V1.01 firmware doesn't work well with his Sigma (17-50/2.8 OS HSM).
2. Reliability of the DA Limited Lenses
It is reported by a DA 40 Limited user that (in Simplified Chinese) the aperture blade of his new lens that has only been used for two months have had its whole mechanism self-disintegrated without any good reason one-day suddenly!
3. The Relation of Rolling Shutter and SR for Video Recording with the K-01
See what this Pentax user reports at the DPR. If it is really true, it is possibly that the processing power of the Prime M processor is insufficient to do both things well at the same time!

Wow! I have nothing more to say!! :-o

The cyan blue coloured line is for the share of the Pentax mirrorless cameras, which is a steady of above 5% throughout the year with the best results in October. However, with the introduction of the EOS-M, Pentax is yet once again the player who comes last as the EOS-M sales has quickly surpassed all the Pentax mirrorless sales as a whole!
As for the market leader in September and October, Olympus is still the winner and then followed by Sony and then Panasonic as the 1st and 2nd runner-ups. It can be seen from the Chart that Pana's place was taken over by Sony back to August, before that Pana is the 1st runner-up holder in the Japanese mirrorless market.
So, you may be curious for what contributes to the slight rise of market share of those Pentax mirrorlesses, nevertheless? I think it is solely because of the recent cut-throat strategy of Pentax Ricoh, see the latest Japanese prices of those Pentaxes and you will realise why!
(in Japanese, all price displayed are in Japanese Yens, model names are shown in table.)
But I just wonder, how long Pentax Ricoh can sustain with such ridiculously low throat-cutting prices of their products? :-o
