.. the "slam" is not such a problem. my mirror hits the lens daily. (if i use that lens). it happens at infinite (ca. 20-30m), after i took the picture, means, when it comes back !! accordingly, the kinetic energy is not so much as if it would hit it in the other direction.

no issue, only if you are above infinite

Some cameras seem to be fine, some are not, it could possibly be manufacturing tolerances,
My 1DIII would catch on my MC PG 58/1.2 till I reduced the thickness of the retainer from the 10 O clock to 2 O clock positions, now I have no issues, but it still catches on a friends 5D.

Thanks sebboh. I read somewhere that auto-rokkor is different from mc rokkor. By the way, the bokeh behind the plant is a bit busy.
i have owned both. they both have very busy bokeh. the auto rokkor and mc versions of the 58/1.4 are identical optically but the MC has more modern coatings. i suspect my auto rokkor may only be single coated, but i haven't examined it closely. the only other difference is that the auto rokkor has 8 aperture blades while the MC has 6. both performed the same with respect to sharpness, contrast, CA, bokeh, and overall drawing style. it's possible the colors may be a bit different, i didn't do a direct comparison.

I will add that infinity can be reached by using live view if you have a 5D2 and would rather not shave the mirror. (My choice ) The retainer has been reduced on mine, so I only have to switch over from the viewfinder for the final little bit of focus ring throw the odd time I need infinity with the 58/1.2.
Helimat - could you expand on that please? (I'm on a learning cure with a new 5DII and just bought a Rokkor 58 1.2 that's to be converted). Are you saying you can focus on infinity, take the picture and avoid any mirror slap as long as you stay in live view?

Absolutely. You have to switch to live view before focusing to infinity, but once the mirror flips up to expose the sensor for live view you are good to go.

Thanks Helimat & AhamB - that is what I suspected. This is helpful (and makes it somewhat easier parting with my 1Ds II - ) Dave
Only bought the second because I found it at a good price, and had Jim B. convert it. One will be for sale soon for sure.
