Re: the Canon Noctilux...

Funny this talk is coming about fast lenses on Canon DSLRs I have successfully transplanted the EOS lens mount to a Minolta 58mm f/1.4 and still achieve correct infinity focus. I did it as a test before I attempt it on a Minolta MC 58mm f/1.2 lens which has always been one of my favorites. Should make a very nice portrait lens on my 20D and have a shallow depth of field wide open. The bokeh with this lens is legendary.

With my eyes in low light, AF can give better results.
With a contrasty subject, If I'm careful, I can do OK with the M7 0.72 rangefinder's manual focus.
Manual focus with standard screens on Canon dSLRs is pretty tough. Even with a Katz-Eye screen in the 20D (split with microprism collar), I still screw up focus with the 400mm f/6.8 Telyt at times. And it's really tough with the standard screen in the EOS 1D mark II. I almost never see crappy focusing with the EF 400mm f/4 DO IS on AF. I usually shoot it wide open. If I choose the right sensor for my composition and put it on the eye of the bird, human, whatever, I usually get what I want.
And I've gotten sharp images with AF inside a dark Buddhist Zendo where I've had to use ISO 1000 or higher for fast-enough shutter speeds handheld. That's with the EF 24-70mm f/2.8L wide-open. Admittedly, DOF isn't as narrow at 24mm and f/2.8 as a 24mm f/1.4 would be. But it's narrower at 50-70mm.

But if you want to get closer and have more accurate focus,
More accurate focus with the Canon???? I am sorry but a Leica will focus much better in low light than any of my canon bodies do.
AF is good in good light, but in low light it hunts and pecks with out some assist. When I am shooting at 1.0 I want to select the focus point not let the camera do it. Often when using my 24 1.4 @ 1.4 I am not happy with where the AF decides to focus to. With my Noctilux I seldom get missed focus shots.
