Good point. I guess I want to make test that can be compared over a long time. I want to be able to repeat the same test with different lenses over a long period of time. I always made many test. This is one of the reasons I own more excellent lenses now than 15 years ago, when I thought it was enough they were Pentax lenses. Well, now I know it isn't! Also I wanted to try determining the resolution of a lens in lpm - just for the fun of it. Now I believe I can. Thanks to you guys :-).
