Pentax Full Frame; first glimpse
#31
Quote:Strangely, the dpreview article mentions 55/1.4 compatibility as "stopped-down" only, and not "fully functional". Sad I wonder what that means exactly. I was thinking about buying that lens, but only if it'll work on FF body with no issues. If it's not usable wide-open on K1, then it's not worth it (it's not exactly cheap for what it is, most 50/1.4 from other companies are cheaper).
Guess you can only check this on the spot and see if the level of vignetting is tolerable for you. Then again, maybe a Sigma 50/1.4 (non-A) is a better all around option, and surely it's a lot cheaper (the Pentax 55 was always on the expensive side). As far as I can remember, the Sigma was available in the K mount.
