Well here is the beginning of my test...SHARPNESS
Lenses involved: Ultron vs DA 40mm Limited (with the Pentax 16-45 tagging along sometimes
because it can)
Tried to take your recommendations from "how to do a lens comparison???" thread that I started earlier
Conducted with no flash, tripod, shuttler release cord, with ambient incandescent lighting. 100% crops from the center.
I ran into problems with using smaller apertures, especially at f/8. DA 40 looked like a blurry mess at that aperture. I would guess camera shake, but the Ultron and 16-45 results at that aperture were much better. Shutter speeds at that aperture were 5 seconds long, which may give explanation
