Ephotozine Review/ FA Ltd series Jul 2011 by John Riley

Last summer, July 2011, John Riley posted reviews of the FA 31, 43, & 77 Ltd lenses on a K-5. He used Imatest charts. They have got some attention in the past but thought I would post them in one thread since the recent re-test of the FA 31 & 43 by Photozone.

I guess you are talking about the 43. I don't think so, because Riley also did a partway in the MTF50 and also did a MTF20 for contrast. There are certainly some similarities in the MTF50 extremes, but the interpretations and subjective parts of the reviews differ. Riley went to f22.
