Originally posted by Canada_Rockies I have to respectfully disagree. I have no problem focusing my M400/5,6 on my K3. In good light, it's easy even with the 1.7xAFA on it. The Tak 55/1.8 is even easier. Is it the O-ME53 that does the trick? I even used it on my KX (film) so I don't now anything else.
I am not sure what you are disagreeing about. I state that the ME Super's viewfinder is a joy to use. I do find the viewfinders of the K3 and KP problematic for manual focusing, especially with telephotos. I have the O-ME53 on both cameras and a microprism screen on the K3, and still find them to be less than optimal. The microprism does black out at f4 which certainly does not help, but that's another story. Perhaps your eyes are better than mine, or your tolerances looser. I definitely get better results with the same telephoto MF lenses on my Fujis than with my Pentaxes. The only time I find this not to be the case is with close up work, where I much prefer to use an optical viewfinder. With more "standard" or wide lenses, the focusing problem is still there with lenses which have a short focus throw (a typical example would be my A 28mm f2.8), but not with ones with a longer throw (K 28mm f3.5), but due to the inherent DOF involved the issue is not really major.
