Here's what David from Leitax said;

Sorry cgiff, my mistake. I didn't know the 40/2 and 28/2.8 are different too. I'm working in the solution for these models now.

Hmm, I think there are a few other OM lenses with the two piece mount.

18/3.5 and 100/2 is tempting. But if the 50 1.2 is bad, that is not so tempting.

The OM 50mm f1.2 is one of the better 50mm lenses I have used - especially at f1.2. It is comparable to the Nikon 50mm f1.2 and to the Rokkor 58mm f1.2. Maybe it's possible you had a bad sample to try out.

55/1.2 sucks comparing with Rokkor IME. 50/1.2 is another level, really.

What they mean re: 50/1.8 - there were 2 types of mounts in the OM world. The earlier and more common one are the one-piece ones. Some later lenses, on the cheap end of the scale, used a 2-piece mount, like the later 50/1.8. Of all the OM lenses I have had (which is a lot,though not the 40/2) the only one with 2-piece mount was the late 50/1.8. The 40/2 was out early-on, so almost sure most if not all of those have the 1-piece mount. At least the earlier-vintage ones should. All the f/2, f/1.4, and f/1.2 lenses (except 40/2 - not sure, and 100/2 - not sure - I don't have those) are one-piece mount.

FWIW.

Hmm, maybe I should try to get my hands on a 50 1.2 to compare it with my rokkor, my sigma and some other fun stufs?

Hey, good idea Andrè! You, me, tripod, rokkors, noct, zuiko, sigma, CV 58 1.4... we could make a great normal-lens test in between us

(mostly you, but still :P )

I have most the OM 50/1.2, 55/1.2 and Rokkor, among others. the OM 50/1.2 is no slouch - very nice. Well regarded and recommended if you can find a nice one for under $450-500.

David, no need for apologies, I only asked about the 100/2. And I checked it and the mount is indeed 1-piece, so that shouldn't be a problem =)

I now have the two zuiko 1.2's & rokkor 1.2. From personal experience, I'm very happy with all three. The performance is great from each and really comes down to what mood i'm in - rubber gripped small, or metal gear solid. Both are extremely enjoyable to shoot with for their respective form factors.

This is really great news, and means that I will certainly keep my Nikon bodies and convert most or all of my Zuikos. Looks like a D700 to pair with the 21mm f/3.5 wouldn't be a bad solution

+1. I love my 50/1.2, even more so since I got a FC adapter (it was difficult to focus wide open on the DSIII, even with the S screen).

It's cool that Nikon gives you FC without a chip, but how does it do full EXIF without a chip to recognize the lens? Do you enter the focal length manually before you start shooting?

Yes, you do, but you won't get the correct aperture in the EXIF.

Focal length and max aperture. Depending on the camera, you can store a number of lenses (9 on the D300) and just select the one you want, or change it if you don't have a particular lens saved. This also enables Matrix metering and improves flash meteirng

You won't get working aperture in EXIF and flash metering may be wonky with the Leitax adapters, since they aren't AI-coupled.

Thanks, Jorgen and Adam. I didn't even realize the D700 had that feature when I owned it. Not that it would've changed my mind about selling it, but it's a nice feature that Canon needs to catch up with.

Metering in general with the chipped adapters is a bit wonky on the Canons. I've become very familiar with my hand-held. If I rely on the in-camera meter, it's always with a little prayer to the gods of photography.

Forgot to mention that one advantage of the OM 1.2 is its size. It's cheap-slow-rangefinder-lens tiny, but is a solid little marvel of engineering. I'd put color rendition on par with the Canon L, but the L manages CA better (by a large margin). Still, it has the distinct advantage of not focus shifting when stopped down, which leads to less out of focus highlights to fringe. Full stops only. Focus, on my copy, has the perfect amount of tension.

The only thing that is a little crappy, is that the smallest Nikon body that will meter manual lenses is the D300. A D90 would be such a nice combo with the OM 100mm f/2.8, and the viewfinder is fairly good for manual focusing. On the other hand, it's always possible to buy one of those shoe-mount meters. Have anybody tried one? How exact are they?

Something like an L-308 would probably be easier to use, but why on earth would you grab an OM 100/2.8 for say $80 and then this mount conversion for another $80 when you could get a 105/2.5 for the same price and it's close in size and a far better lens?

1. The Zuiko is 60% of the length and around half the weight of the Nikkor
2. I own the Zuiko already
3. In this country (Thailand), the Nikkor is between $150 and 200
4. It's fun to try something different. I also have the Nikkor 105mm f/1.8. Very nice lens, but it's big, and sharpness degrades beyond typical portrait distances. The Zuiko is very sharp, also at infinity, particularly at f/4.0 and 5.6.

The shoe mount meters are a larger PITA than simply checking the histogram afterwards. They're reasonably accurate for normal range lenses (35-50mm-e).

Honestly? Lack of metering was never all that much of an issue with either the D50 or D40 for me. I wouldn't shoot action with non-CPU lenses on them, but chimping the histogram, is not that big a deal and much more reliably than stop-down metering as well.
