I was actually refering to a test of the Pentax FA645 75/2.8 done in a Swedish magazine and performed by Hasselblad. It concluded that the Pentax and the Carl Zeiss were similar in both MTF values and result on film. I still wouldn't use the Pentax on the 35mm slr though. Pål
Lens resolution tests.
Just for fun, I did a search and found the follwing link: http://www.phootos.com/Library/resolvetest.htm This fellow claims that a Hasselblad CF 80mm / 2.8 T* at f2.8 is hitting 500 lpmm, and a Contax G 45mm / 2 is getting 530 lpmm using his testing procedures. This would seem to obviate some claims that small format lenses are significantly better than 35mm lenses, and agrees with what I have personally obseved about the Carl Zeiss lens for the Hasselblad.

Recently Yoshihiko Takinami wrote: Oops! I am very sorry. I found out from my doctor that I have a rare eye condition that throws my vision off by an infinitesimal amount. So all of my lens tests are wrong and should be ignored. Sorry for any problems. I hope no one ever read them. Hi Yoshihiko, I am sorry to hear about the probolem with your eyes! Is it appropriate to tell us a bit more? In which way are the resolution results affected? My first take on this problem is that as long as the results are CONSISTENTLY wrong, they are CORRECT. In other words, we are not interested in absolute results but in the RELATIVE resolution of one lens compared to another. With that in mind, I would encourage you to not give up on lens testing.
