still stuck on which adapter to buy, all the ones priced from $20-60 look exactly the same.
I shoot a lot of manual focus lenses on my 5D...Olympus, Zeiss, Leica, Pentax, and Minolta. I've been using adapters from the following: happypagehk, big_is, haoda fu, fotodiox, and cameraquest. I probably have most of mine from happypagehk (he's the only one that will code the adapter to display the lens' focal length and max aperture in the EXIF data). Big_is will code the adapter for focal length only (I have some of these also). I haven't been disappointed with any of the adapters from any of those mentioned (except the cameraquest locking spring needed some modification to lock the adapter to the lens)...they all do what they're supposed to do. One thing about happypagehk...his adapters sell pretty fast (especially the Olympus and Zeiss). When you see his listed, its best to get one right quick if that's what you decide on. Realize though that buying an adapter can be a crapshoot. A lot depends on the thickness of the unit...too thin or too thick can throw focusing off.
Also, you may want to consider changing out your camera's focusing screen to one that will aid manual focusing.
