This post will be a bit of a lengthy introduction. I shot Pentax film cameras until I went digital in 2002 when I switched to Canon (D30). I started looking at film again about 2 years ago when I was thinking about getting an EOS 3. I eventually decided that if I was going to use film again, I would likely only use it for artistic work that didn't require me to work in very challenging lighting conditions, and that allowed or required me to work more slowly. I decided for these reasons that the EOS 3 was overkill and I went back to Pentax film bodies, eventually collecting probably a dozen in both M42 and Pentax K mount. Somewhere along the way I also ended up with a Mamiya BR67 Pro S as well. Fast forward to this past Summer. I took a trip with my kids and decided that I would love to start collecting family memories on film again. Call it nostalgia or whatever, but I wanted my kids to be able to experience the same shoebox full of double prints that I grew up with, shot on real film. I took my Pentax LX and ME, one with black and white film, the other with color. Although the pictures turned out nice enough, I struggled quite a lot with focus, especially indoors under marginal light. I kept thinking to myself, "I should just put the Pentaxes away for the rest of the trip and grab the 5D mk iv." This got me looking at the EOS film cameras again. Of course, I went straight to the EOS 3 that got me started back on this film journey to begin with, but I kept seeing the Elan 7NE that is newer than the 3, and has some upgraded features like ETTL II and a supposedly better focusing system. My Elan 7s (Japanese version of the 7NE) arrived and I ran a couple rolls through it with my 24-105 f4 L and 70-200 f2.8 L and I think the Elan struggled as much with focusing indoors as I did with my manual focus Pentaxes. Additionally, since I use mostly black and white, when I had a filter on the lens indoors forget about it! The camera can't achieve focus under room lighting at all with a filter installed. I wouldn't say that I have buyer's remorse because I really like the camera and it performs very well under all other circumstances, but I did wonder if the EOS 3 would be able to nail focus under the conditions that the Elan 7s fails. I just ordered an EOS 3 and am anxious to find out. Once it arrives, I'll compare the two side by side and decide which is better under low light conditions with my lenses. Of course, I am also aware of the EOS 1v. I suppose once I have the 7s and the 3 sorted out, I'll have to grab the 1v as well so I can declare the absolute winner of Canon's film trifecta. So, since I have nothing yet to compare (the EOS 3 should arrive this Friday), I'm curious to hear the thoughts of anyone who has any relevant experience with any of these three bodies. Have you shot them indoors at night under normal room lighting, with a typical contrast filter (I use green when photographing people) installed? In your experience, how do either, or all of these cameras perform in comparison to each other in terms of focus speed and accuracy? Does a Canon autofocus 35mm film camera exist that will outperform all three of these in low light?
