I currently shoot with a Rebel 2000. Even with a fast lens (50/1.8, 100/2) it's fairly hard to see what's in focus; DOF preview seems to be useful mostly as a bokeh preview, since I'm not able to tell what's really in focus and what's a bit (but significantly) out of focus. Yesterday I had a chance to play with an old EOS 1 and a 630, both with a 50/1.8, plus a new EOS 3 and Elan 7 both fitted with a 50/1.4, and then compare it to a Contax Aria with a 50/1.4. All cameras had their standard focusing screens. The basic observation is that among Canons, manual focusing is easiest with EOS 1, followed by 630 and 3, and lastly by the Elan 7; however, everything pales compared to the Aria+50/1.4 with an extremely clear distinction beween what's in and out of focus. Here are my questions: 1. Are the split image focusing screens for EOS 1/3 and the one for 630 easier to focus manually (apart from the split focusing aid) than the standard ones, or are they the same? 2. For some reason I felt that manually focusing a 50/1.8 on EOS 1 is easier than a 50/1.4 on EOS 3, though they are supposed to have the same screens - could it be that the ECF machinery requires the EOS 3's prism to be darker/less contrasty and thus harder to focus? 3. Is there anything in the Canon EOS world that approaches the ease of manual focusing of the (entry level!) Contax Aria? Thanks in advance!
