I don't know about the Rokkor. It's a great lens when I use it, but I don't as much as I'd like to. I refuse to carve mine up, so I've been thinking about trading it towards a ZM 35/2 Biogon. Just haven't found the impetus to do it yet.
Tell you guys what, I should have some shots to contribute this weekend (though probably not very many).

who said anything about carving, you just have to remove a few screws and then screw them in again. it's totally reversible too (unless you shoot nikon).

You guys are certainly making a strong argument for the Rokkor 58/1.2 at any rate. Alexandre's got a clean copy on the B&S boards that's kind of making me wish I still had a Canon on which to shoot it.
why!?! you've got the only FF slr that get get infinity with no mirror hang on the rokkor king.

so the noct-nikkor is only good for night time flaring? bokeh so-so? (rokkor better?)
it's designed to be extremely well corrected for coma and is not the sharpest f/1.2 lens (neither is the rokkor). i've never seen a good comparison of it's bokeh to other lenses. tbh all f/1.2 lenses have pretty busy bokeh at f/1.2, the rokkor just happens to be a more pleasant type of crazy than most (always a matter of opinion).
i do know that nate (twok) has one of the most awesome portrait ever with that lens wide open where the bokeh definitely contributes to the photo. hope he doesn't mind me linking it.

There is a old thread from this forum about four years ago that had a lot of debate about the Noct-Nikkor vs. the Rokkor with a lot of shots from each lens, but never the same subject as nobody had both lenses if I recall correctly. My memory is that the Noct-Nikkor had slightly creamier bokeh and clearly better chroma correction. I did think, however, that the Rokkor was clearly better stopped down where the Noct-Nikkor was not all that great. These are just my impression, however, and with full disclosure I own the Rokkor and have never used the Noct-Nikkor.

This matches my experience with my Rokkor. Stopped down to f/2 it is considerably sharper and often has better bokeh. Nevertheless, some shots look best and quite phenomenal wide open. I probably shoot it at f/2 more than wide open, however.

I do? I was not aware of that. Alexandre's copy is already an EOS convert, so it would be silly for that not to go to a Canonite, but I'll have to look into an Alpha conversion. On a scale between "any monkey can do this" and "do you work in a machine shop?", how's difficult is the Alpha conversion?

I really enjoy your photography, love the film
thanks! all the other f/1.2 lenses i've shot with (rokkor 50/1.2, canon FL 55/1.2, olympus pen f 42/1.2) are sharper wide open than both copies of the rokkor 58/1.2 i've owned. stopped down it's harder to say as they pretty much all outresolve the sensor across the frame by f/2.8. all the canons are supposed to be pretty sharp wide open (for an f/1.2 lens) as are OM 50/1.2 and the pentax 50/1.2. i can only talk about the ones i've actually shot with though.

anybody that can work a drill and buy sandpaper can do it. the conversion to sony is exactly the same as the conversion to eos was prior to when people started selling kits for it except that you don't have to do any trimming of the retaining ring to get infinity. unfortunately, unlike eos, nobody sells kits for it now as far as i know, although there's this: http://www.pbase.com/pganzel/image/71175094
you can just follow paul's (cogitech's) instructions and replace the m42 to eos mount with a m42 to a-mount adapter (also, don't bother trimming the retaining ring): http://www.cogitech.ca/Rokkor/index.html
i'm not a big fan of that method since it's destructive, but it will work just fine. the better way to do it is to just make a smaller spacer instead of trimming the existing one down (this requires a lathe though). in retrospect i should have just made a few dozen to sell when i converted mine instead of just one. you can make a more ghetto spacer without a lathe if you want too: http://georgp.zenfolio.com/mc_rokkor_58_conversion

I can work a drill (press, anyway, I'm a bit of a menace with the hand-held) and as long as I don't have to do anything but buy the sandpaper...
Thanks, D. It does look simple enough. I'm excited about this right now, but here's what I think will happen. I'll buy one and do the conversion. I'll shoot it for about a week on the a900 because I've never shot anything that fast on it and I want to see if I can focus it with the OVF. Then I'll remember why I don't buy ultra-fast lenses anymore and there will be an Alpha mount convert (with James Lao chip!) for sale on the boards.
I would love to see the comparisons.
