Will this lens clear the mirror of a 5D or 5D MarkII? I don't have any problems with the mirror of the 1D series but I just ordered a 5D MarkII and would like to know before hand whether or not. Can somebody enlighten me, please?
Even once modified to achieve exact infinity focus, the Rokkor 58/1.2 protrude too far into the mirror chamber and a 5D/MarkII will need a mirror shave to avoid the rear element being hit at infinity.

I managed to file back the shroud around the rear element, and it only sporadically causes mirror lockup. ANd I think I've converted mine to go a very small hair beyond infinity.
Personally, DON"T SHAVE THE MIRROR. The Rokkor is sought after specifically because it is a "old" lens design, with no floating element movements. So, this means that you can have accurate sharpness at some distance with the lens at a non-specified distance from the negative. This in turn means that you can have the lens be 1 or 2 mm's further than it was design, and all you will have is EQUALLY sharp images ( compared to original specs), lacking infinity focus. In most cases, this lens has a focus adjustment ring in the front that can correct for most of what the 5d makes you lose, but just assume that you will not need to focus out past 20 meters. I use it on a 5d and 5dII, and it works like a charm like this. This is of course up for specific body and lens variation and you are always best off testing the camera by "bulb" exposing the camera, sans lens, and then mounting the lens, and releasing the shutter, which allows the mirror to return through the full movement without any pressure bearing on the mirror assembly, so if there is a block, you have a FAR lesser risk of damage.
Rokkor 58/1.2 on a 5D (is this referred to as 'classic' now?). If memory serves me, this was shot at f/2. I really need to use this lens more than I do...
I had one for a few months. It was good, but didn't really wow me like it did some people here. Sharp, decent bokeh at times, average at others. I much prefer my Sigma 50 f/1.4, and I really prefered the Rokkor 50 f/1.4 when I was using it (that's an exceptional lens).
I was just wondering .... how do you know when to stop or how far you can focus without the rear hitting the mirror? Is there a way to determine the furthest point you can go without actually doing it until it touches the mirror?

My Rokkor will not focus to infinity, but mainly because the rear reaches so far into the body of my D700 it hits the mirror. There is very little left of the spacer to sand away.
. Thank you for your input, guys!
