Thanks sebboh, did not know that. I guess if I were to do that I could use one of my current EOS-NEX converter which would be neat enough. Main interest is for the NEX, but it would be a bonus to use it on the Canon too. Do you know if there are any risks involved (apart from mirror) - I am thinking of offsetting the lens package or something, ie ruining the lens' qualities?
the only real risks are in scratching the large rear element with a screw driver if you drop it. mount replacements are much nicer than adapters for a solid consistant mount to the camera. jim buchanan from this forum sells a kit, not sure if there is anybody more local to you that sells them, but i imagine there must be a few people in europe.
Leitax offers a Rokkor kit; they are based in Europe. http://www.leitax.com/Rokkor-lens-for-Canon-cameras.html I've used their Leica and Contax adapters, expensive, but very nice quality. I have no experience with their Rokkor kit.

The Leitax kit looks nice, and is reasonably priced, however the rear element retainer will have to be reduced for use on a 5D series camera for use much beyond 10m/30'. Even after being reduced heavily, there will still most likely be contact with the mirror at infinity, but just at infinity. I did reduce the rear retainer myself once, so if you are handy enough (and careful enough) you could go the Leitax route and finish it off yourself. Jim Buchanan would be my recommendation, but of course being in Sweden would make that more difficult.
Thanks sebboh, heli, john and ricardo, much appreciated. I will definetly continue look for a rokkor 58/1.2. Dont dont think I ever use it on far focus, the qualities are fairly close (to me) seen by examples here.
@wfrank: I use it on a-mount and I don't think I have any infinity samples to share . Like you say, it's a closer focus lens. Just please don't go hacking at the rear retainer

actually i'm pretty sure it's optimized for infinity focus sharpness wise. even wide open it is noticeably sharper focused at long distances than focused closeup. nobody really buys the lens for sharpness though. it's certainly sharp enough that i would choose it as my only lens on FF if i had to choose. but yeah, it's most interesting at close to medium distances even if it's not as sharp as it is at infinity.
I've noticed that my 58 1.2 (metal focus ring version) has quite a lot of play. Does anyone know of any tear down tutorials for this lens, or know how to tighten up the lens so the focus ring and aperture ring do not have any play. Both the aperture and focus rings rock slightly, both when turning them, and when pushing or pulling them towards or away from the camera body. Wouldn't mind giving my elements a good dusting too whilst I'm at it.

It does fine at or near infinity. I don't believe in 'pigeonholing' lenses. Reducing the rear element just made it more useful to me. It is totally safe to do if removed before machining.
Tried it. Not bad, sharp enough but different than the 58/1.2. The bokeh is much more nervous. The 50/1.4 is actually closer to the legendary 58/1.2 IMO.

+1 and i'll add that that the 58/1.4 is lower in contrast despite having one less element than the 58/1.2 and 50/1.4.
Did a quick test of Rokkor 50/1.7 yesterday (first MD lens I've ever used).Sharp,compact and nice to handle,but lacks microcontrast and has rather bland colour rendition.Not bad for 25 euro lens but I'll probably re-sell it.
Didn't get a chance to look at all the pics featured on this thread,but will do it soon.
This seems to be an outstanding lens (for the price).
I used to shoot a couple of m42s on my 5Dc (300 Pentacon F4, Pentacon 50mm 1.8, Tair-11 133mm 2.8).
I want to get either a low light fun/play lens such as the Rokkor 58mm 1.2 or a Fisheye like the Zenitar 16mm 2.8 (will get them both eventually,but I'm not sure which one to get first).
Obviously they are in a different league,but I'm inclined to go for the low light toy first.
On the 5Dc i had an issue (if i remember correctly) with the 50mm 1.8 (pentacon,m42).
Near infinity the mirror would slap the back end of the lens..
Is such behaviour to be expected from the Rokkor 58mm 1.2 as well, when focus near to infinity is attempted? To what distance is ok to focus without having to worry about the rear-mirror-slam ?
Also how do you adapt the Rokkor 58mm 1.2 to Canon? are there adapters from Minolta MD (?!?) to Canon EOS EF?
Are they just simple metal-ring adapters (such as the M42 to EOS ones) ?
Any input would be welcome and apologies if this info has already been covered pages ago (I only managed to read 10-12 pages).
The 58/1.2 will have mirror issues with the 5D(2),
There are kits available to convert the minolta mount to EOS,
Other options are Nikkor 55/1.2 & 50/1.2, OM 50/1.2

this was actually discussed a fair bit on the previous page of this thread. the 58/1.2 will cause the mirror to hang on a canon 5d focused past 10-30m. you can get a bit further by doing some trimming of extraneous lens bits, but to really get infinity you need to shave your mirror (or shoot a sony). minolta lenses are not adaptable to canon, they require a mount conversion. you can buy a kit for such a conversion from leitax (spain) or jim buchanan (US).

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.
thanks for the input. of course this is not a lens that you would use to focus to infinity,but sometimes...when you want to shoot something in lowlight...which is a bit further away i wanted to know which is the 'appropriate' distance befor the 'slam' occurs.
sebboh pointed it out for me.
thanks.
.. 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.
. Like you say, it's a closer focus lens. Just please don't go hacking at the rear retainer 
, a few weeks back ...
