Informal lens test - Interesting

I picked up my new KX today and wanted to check that my "collection" would fit and work as expected. I set all lenses to 50 mm (if possible) and shot 2 stops down from full open. This is NOT a very technical test - all photos hand held, existing light. The first photo is the un-cropped shot. the others are clips from the representative lenses

Un Cropped Image

50 MM Nikkor Macro (remounted to PK)

pentax DFA 18-35

Pentax 18-55 AL

pentax Da 18-55 AL II

Pentax PZ 28-80

Pentax FA 35-70

Minolta Rokkor 50mm f1.7 (Mount adapted to PKA)

So The 3 sharpest lenses COMBINED didn't cost me $100 - life just isn't fair. The 35-70 and the Rokkor have always been favorites now I know why.

How do you adapt the Minolta Rokkor mount to PK/A? Is there a web link you can point point me to?

The minolta rokkor is a great lens. Mine was a rokkor-x f/1.7, it was the first lens I owned that was faster the F/2! It came with very noticeable fungus and the focus was gunked up from 10-5 feet but neither comprised the photos I took with it. It was great wide open but I also liked using it stoped down for landscapes as well. Maybe I'll get my mounted to K too!

Art, while life may not be fair, in this case it is GENEROUS - and we are all lucky to live in an age where we can get such excellent glass for so little money
