I'll finish with a possible suggestion - I had an Auto Sears 50/1.4 on the D700, with optical adapter, on Sunday and I loved it. There's a caveat though, the D700's mirror is more forgiving than the 5D's so it might not work on that. More experienced Canon peeps will know how things are for the 6D I think I've read more forgiving?.

Yeah that Sears 50/1.4 was most likely made by Pentax, if it's K-mount.  The Pentax 50/1.4 I irreversibly modified for use on my 5D2 works very well, but right at infinity focus it does hit the mirror.  The 5D2's mechanics tolerate this, and it is easy to avoid, but I haven't tried it on my 5D3 or a 6D, nor do I plan to.  If anyone wants this lens, I'd liquidate it for $50 shipped.

So how about one that will work - a CZJ 50/2.8 Tessar?

IMO, f/2.8 just isn't fast enough for a 50mm.  For a 28mm and wider, fine.
