While back, I purchased a Sears "multicoated" lens from ebay, I belive $12 or so, had "A" for KR but looked like someone instead of removing the pin, removed the entire electronic plug (little that it was)...
I've used it with extension tubes on K10D while back, and it produced some reasonable results:
But because it was completely manual, and would not stop down, I barely used it. Well today, I picked up a beater "Prospec", KEH would rate it UGLY, but, the bayonet is flawless, and also "A" KR, lens almost looks identical to Sears (but not macro feature), so I removed the bayonet from Prospect, removed the KR pin, mounted onto the Sears and what do you know - it works as an "A" lens on K10D
Anywho, played with it a little this eve, I'm finding this lens to be a fairly sharp - don't mind the compositions, but here are few shots (RAW/DNG to JPEG in Pentax software) f/2.8:
But this is what I noticed - shots above are all straight conversion in "non-macro" mode. Once the macro mode, unless its stopped down to F11+, it is very soft, almost dreamy like effect.
Also straight conversion f/2.8 "macro mode":
So again, don't mind the composition, but took a snap at Dad in macro mode, converted as above and "smart sharpen" at 100% 0.3 pixels:
Its like getting three lenses in one:
Sharp in non-macro
Sharp in macro (small apertures f/11+)
Soft focus in macro (large apertures)
All for the price of soft focus screw-on filter, and all for $12
Never had so much fun experimenting, taking lenses apart and exploring various potentials of one lens on Pentax DSLR
