New here so please be gentle with me ! I'm a huge fan of using my older lenses on the Olympus micro-four thirds bodies. Biggest collection is M42's. Last year got the Camdiox reducer for the M42 mount. Works a treat particularly with the Porst 55mm f1.4 regards sharpening things up. Considering getting one for the Canon FD F 1.4 to play with dof, but confusing info out there about flange distances etc. Another option is to get the Adaptall to M42 ring to enable me to use my Tamron Adaptall lenses, and possibly use the Adaptall to OM adapter. I'd love to hear anyone's experiences regarding using the focal reducers with a wide variety of mf lenses, without going to the expense of buying several focal reducers. At approx £50. a pop via eBay they aren't cheap !

The focal reducer with likely most applications is for EOS, for which many cheap adapters exist (M42, C/Y, Nikon, etc). However, FD cannot be adapted to that. EOS could have been a better choice instead of M42.

It was the EOS version I went for. I wanted it for PK lenses but no PK version was made at the time.
Adapting the EOS version to PK has worked fine with all my film era lenses. Results were less impressive with my fish eye - not just because it was a DA lens with insufficient coverage, but I suspect the very short focal length showed up minor errors in the dimensions which weren't relevant for 50mm & longer lenses.

More recently I've been given a OM mount 28mm macro, I've not noticed any problems adapting the EOS reducer to this lens either Smile
