could only happen if they do a half frame camera, the DA21 doesn't have enough image circle to cover a full 24x36 35mm frame. The DA40 and DA70, OTOH do, and I've used them on my SuperProgram and MZ-S.
Oh no, no, I'm thinking of the "Pentax HD D FA 21mm F2.4 ED Limited" which is quite a mouthful, and a full framer... with nice image samples and a hefty price tag for there being all two full frame cameras that support it.
