Originally posted by cali92rs On your K-3, if you get an the exposure that calls for f8, 1/125, ISO 400. On you K-1, you will get the same exposure and DOF with f11, 1/125, ISO 800. Your image quality will also be the same due to the stop advantage regarding DR, noise and diffraction.
Actually, you don't: the luminous exposure is defined as the amount of light per unit of area. So f/11 and 1/125 will give you less exposure, which is why you have to raise ISO to compensate.
But this is just nitpicking on a technicality, please go on...
P.S. By the way, the image quality will not be the same, because:
a. equivalence's assumptions are not fully met
b. equivalence's assumptions are awfully incomplete
