Just hoping for some guidance. I just got a GXR kit and never used one. I have an EOS 5D with 2 C/Y lenses with EOS adapters. I have a canon 24 1.4 FD converted to an EOS and a 55 1.2 FD which has an EOS mount which I could convert back to an FD mount. So should I trash the c/y to eos adapters and get an c/y to M adapter, or should I get a Canon EOS to M adapter and use all the lenses I have with it? I suppose an FD to M adapter has no advantage over the EOS to M adapter. Please advise. Thanks in advance!!!

The issue that comes up with stacking multiple adapters has to do with the variations in how well the adapters fit each other to properly center and align the lens. Each coupling adds the possibility of something being slightly off, and the potential for misalignment. I've also found variations in fit between different lenses and different brands of M-mount adapters.
So the economical thing to do is to buy an adapter to allow all your lenses modified to mount on Canon EOS mount to be fitted to the GXR. But the best thing to do is to obtain a mount adapter for each lens native mount to fit it to M-mount.
Somewhere in between is probably the practical thing to do: buy a dedicated, high quality mount for each of the lenses that you'll be using most of the time on the GXR, and buy a decent EOS to M-mount adapter for the rest that you don't use terribly often.
I've got mount adapters to fit Nikon, Pentax M42, Pentax K, and Olympus OM lenses to FourThirds SLR, Micro-FourThirds and now M-bayonet mounts. As time as progressed, however, I've slowly acquired all M-bayonet mount lenses for my normal use and retained only the Nikkor macro capable lenses that I adapt to M-bayonet. Why? Because, in general, the M-bayonet lenses are smaller, better performing, and sometimes faster than the lenses I was adapting: I just like using them more. And I can also use them on the M9 and other M-bayonet bodies I've got, where the adapted SLR lenses really only make sense to use on the GXR since they don't have the rangefinder coupling.
(I don't use the SLR lenses that often anymore, so I bought one very high quality Rayqual Nikon F to Leica M adapter. It fits perfectly, with no slop whatever, on all three of the Nikkors I have kept and its mount release does not mechanically interfere with the Nikkors' aperture ring, the most usual cause of issues IME.)
