Another from the 85mm L 1/8th @ ƒ1.4 ISO 800 handheld in a local pub. I like the way the individual planks almost, but not quite merge into one blur after only a few inches past the point of focus.

I've been drinking there about 17 years and still had to have these pointed out to me!

^ 85L showing its "true colours" there.

I really hope the 85/1.2 SSC Aspherical has less CA.

It's bad alright, but conditions were pretty much perfect for CA's to rear their head. Anyway I still like it a lot despite the obvious flaws.

Some great zuiko shots here. I must say, the 55 looks pretty good...

The zuiko 50 1.8 has rather hard and harsh bokeh to my eye. Quite distracting

True. But it is in good company with the EF50/1.4, Nikkor 50/1.4, Zuiko 50/1.4, Minolta 50/1.4, Pentax, Nikkor, Minolta and Olympus 50-55-58/1.2, both versions of Summilux 50/1.4, Zeiss 50/1.4 and many other ones (to a degree and depending on circumstances, just as usual).
Til' now I have seen two lenses that differ from the bunch; Sigma 50/1-4 EX and Canon EF 50/1.2L - both having some sort of focusing problem. Maybe Sigma can fix their lens, Canon seem to have to redesign theirs.

If your opinion is different it's OK... I nearly always prefer as smooth as possible.

I think harsh to a certain degree is fine and sometimes useful but considering the close focussing distance in the above photos the result is very harch. The edges of the oof areas are very contrasty.

Ulrik, you take great, intimate portraits, be it faces -- or other body parts. Are you going to convert your Rokkor to Nikon mount or are you going to stick with this new Nikkor only?

Thank you!

Glad you like it!

I'm not quite sure yet. I do like this 50 1.2 AI-S, but not 100% as much as I like the rokkor on the 30d, and the larger pixels and the larger sensors on the d700 should give the rokkor even more love. The firm I have been talking to wants about 200-400 USD somewhere to do a CAD-computer controlled mount-fabrication, infinity adjustment and shaving of aperture ring to make it work on a nikon camera. I have not yet decided if I want to do that (it is irreversible of course), but I'm really tempted. I have to use the 50 1.2 for some more time before I decide I think!

On a second note, I love manual focus with nikon, the arrow/ring thing makes it so much easier, just as th eviewfinder is great! I think I'm in love

I'll have a 180 2.8 lens in any day now (ai-s), looking forward to test that out too!

Ulrik,

I am 99% certain that you could convert the mount to Nikon in exactly the same way it is converted to EOS.

I think all that is needed is to reduce the mount shim much more (or scrap it completely) and find a Nikon replacement mount that is very thin.

I see you already found this guy who figured it out: http://forum.manualfocus.org/viewtopic.php?id=11163

I also thought about converting a Rokkor when I saw these images...

Hmm, maybe I should try to do that. But finding a nikon replacement mount is hard enough :P Any tips on that? According to my calculations, I would have to remove the shim completely and screw the nikon mount directly on. But I have had a hard time finding an actual mount.

There must be Nikon-to-? adapters around that could be used as a new mount, but if all else fails, buy some cheap "parts" lens off ebay (or local shop) and use it as a mount "donor".

I actually found some stuff at rugift now, but I don't know if it is really usable, maybe I should get an old nikon lens and dismantle it instead.
The adapters go for like 89 USD ++, and i can get a battered nikon lens for far less.

Does that mean that it can also be converted to an M42 mount? That would make the Rokkor more accessible to many more bodies?

Sure. It certainly could be. Just need to find one of those m42 male parts or grab one off a dead M42 lens. Then, it would be as simple as sanding the mount shim down more and fastening the male M42 mount to the lens.
