On my way to change analog Contax for Canon 5D I'm looking around to find the best (and most solid) adapters and reading all the treads I miss information on which adapters most of you use - on the web I've seen simple ad-on-adapters and adapters which completely repleaces the original C/Y-bajonet.
As to complete replacements I've seen some that fits small C/Y-bajonets (like on 1,4/50 or 1,4/85) but do there excist a type the can completely replace the bigger C/Y-bajonets (like on 2,0/60 S-macro or 2,8/180) so one might avoid 'the fin-problem'?
