OK, thanks for the offer. You don't need to run anything for me thank you. No, I don't know which ones to try. But if I don't do a film test how am I are going to know if the two highest testing lenses with the same result are really the same or one is better and the camera just cant resolve that difference?

There are several * lenses in our lineup, and other non-* legendary lenses as well. I.e. I don't know if there is a difference between the A* 300 2.8 and the FA* 300 2.8, but we will find out. They have different optical formulas. If you know the answer to some of these differences on film, by all means share. We will probably not do a film test, it just adds another dimension we are not prepared to undertake right now. rg J. C. O'Connell wrote: > Ok, thanks for the feedback.
