Canon EOS 5D, Oly OM lens thread, anyone?

Ebay seller HappypageHK has IMHO the best eos adapters available for the price. Programmable chip for exif data and comunicating max aperture to the camera (important for metering at times).

These are with the Zuiko f2/28mm on 5Dii. This lens is an anomaly for me. It vignettes a fair bit down to f4 but sometimes I really like that. It's sharp and has great 3D punchy contrast.

Is it easier to use OM lenses on a Canon DSLR than FD? I read that buying an adaptor in order to use FD lenses is 'a waste of time,' but looking at some of the images above I'm finding that hard to believe. Are the FD and OM lenses really that different physically?

Also: where in the UK is a good place to source EOS to OM/ F/ FD adaptors? I know you can get them here:

I also saw this one:

Does anyone have any tips?

Best regards,

FD lenses require an adapter with a glass element to reach infinity focus as the register distance is shorter than Canon EF. The degradation from the extra glass makes the adaption not worthwhile.
The OM has a register distance is longer than the Canon EF so no glass element is required. A simple adapter ring that makes up the difference in register depth is all that is needed for OM.

Some FD and FL lenses can be converted via exchange of lens mount to EF. Not many and the process is not reversible either in most cases.
 
Boo - that's scuppered my plans to have two systems (manual focus and DSLR) where the latter could use the formers lenses. Does anyone do this with an FD/ EF setup? If not, what do people use:
  • OM and EF?
  • F and EF?
  • Pentax and EF?
perhaps I should start another thread.......

Best regards,

I wasn't a fan of the 35/2. If I'm using a fast lens, I tend to want to use it wide open. I found that the 35/2 gave poor results (lack of sharpness, coma, etc) at f/2 so I sold it. That and it wasn't nearly as small as it's counterparts.

Stopped down it was fine, but nothing special.

The 28/3.5 is a tiny sharp little devil. Very nice lens, but slow.

The 35/2.8 is not all that special either in my opinion, but it works.

I'm getting major overexposure problems especially in low light w. my OMs on my 5D. Can't find decent discussions for this on web.

Are you shooting Raw and post-processing everything?
Using center-weighted metering instead of evaluative?
Metering at full aperture even at larger than f4?
Adjusting exposure for each lens performance?

Thanks.

FWIW I actually had the same problem. My quick and dirty solution was a LOT of exposure compensation (like, a whole stop) when I still had my 40D.
