(Source: http://pentax.photoble.net/?exif=091004009)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
