@carusb Love these, Chris. It shows how close the lenses are to each other. You will see abberations when you use the lenses adapted onto a digital camera, but they wont be far apart. The Pentax lens coming out on top courtesy of the extra money spent on polishing and coating. Native lenses are built to a Standard and are "Quality Assured". 3rd party lenses are built to a budget and are "Quality Controlled". eg. 1 in 100 is thoroughly tested.

@Jim_Graves All good points, Jim. Was it you that wondered whether the Pentax was actually built by Cosina? I'm a bit inclined to doubt it, among other things, the focus apparently turns the "wrong" way. I don't have these lenses to hand to check, but I will next week.
