erik_loza Posted June 27, 2003 Share Posted June 27, 2003 Thoughts from those who have used the older, non-IF 400 f5.6's? Thanks in advance! Link to comment Share on other sites More sharing options...
ilkka_nissila Posted June 27, 2003 Share Posted June 27, 2003 I haven't used it but CdI gave the ED non-IF an excellent test report. The optical performance is apparently significantly better than in the later IF version. However, it may be a little slow to focus since you really move the whole lens to focus! Have you found a source for this lens? If so, I'd love to hear what kind of experience you have with it. Link to comment Share on other sites More sharing options...
