Originally posted by Cuthbert does it also work with 50 mm macros?
For the zoom, ok mine was in pretty bad shape,
I am not sure if AF080 works in the 50mm, with the closer macro distance. Perhaps somebody can answer.
For the smc Pentax-M Macro 1:4 100mm, I just took 2 test photos at 50mm and f/5.6 and here are the camera jpgs from the K-01.
There might be some reasons for the bad images reported from it.
Firstly , wear as you mention, The copy here is pristine and tight as a zoom needs to be. Old zooms tend to lose corner sharpness, in my experience, or get lopsided blur as they wear..
The build quality of the copy here is similar to all the other good -M lenses in the collection here.
Secondly, when not in "macro" the minimum focus distance is quite long, more than 1.2 metres.
That might lead users to think it is not sharp, indoor portraits etc.
The first photo was focussed on the dial needle. There is a bit of color fringe at the lamp, however the lamp is a bit over exposed.
The dial numbers are still fairly sharp at 100%
The fence test , second shows that this lens across the frame sharpness at 100% is as good or maybe better than the other old manual zooms I have here
