Pentax M 28 f3.5 on K20D soft corners?
Jul 25, 2009

Hi,

I've just purchased a M 28 f3,5, just for fun. I like using old lenses on DSRL.

But I'm quite disappointed...yes distortion is low, colours are great, falloff is not a concern, sharpness is ok even wide open in the centre. But I found that, shooting landscapes (at f 8) extreme corners are quite mushy. This is strange for a foll frame lens on APS sensor...faulty lens? or too demanding sensor for a 30 years old wide angle?

Mr. President, I'm not saying we wouldn't get our hair mussed. But I do say... no more than ten to twenty million killed, tops. Uh... depended on the breaks.
