Wow! What a practical solution to the dark blindness of the K-7! No more worry about the super high noise of higher ISO speeds other than the base ISO speeds of 100 and 200 only! No more worry about the K-7 of being a "Daylight DSLR"! No limitation of such forever!!
I believe it does work. Just try it out yourself if you're really pissed off by the problem! It can also be used for taking movies! Really great idea and much useful! Thanks, guy! You're really so clever and what a really simple *solution*!!
