Latest Review Posted | SMC Pentax-F 28mm F2.8 I stumbled across my copy in a 2nd hand shop - they did not know what they had so I got it for a song. So far most of my the work I have done with this lens on K-S2, but have recently started working with it on the K-1. It's sharp right through it's entire range of f/2.8 - f/22, corner to corner, and is amazing for it's age and build. The only reason I gave this lens a 9 for sharpness is that the modern lens do beat this out - but it's close. You'd be hard pressed to find a sharper 28mm in it's normal price range. The only negative I can think of (if it can be considered as one) is that the lens correction in some PP programs is very heavy and needs some manual adjustment for full frame images.
Here are some sample images.
