Once upon a time Leica made an SLR camera called the “R” series, consisting of cameras called the R3 through the R9. (Then they stopped.) Lenses for earlier Leicaflex will not work for this adapter.
Metabones Leica R Mount Lens to Sony NEX Camera Lens Mount Adapter II (Black) $99 http://bhpho.to/1GrjVLh
There’s also this one from Novoflex that is twice the price but not twice as good: http://bhpho.to/1FO9NBz
The Metabones IV adapter was the only one that figured out how to use the camera’s baked in PDAF sensors to directly drive the autofocusing of Canon’s EF lenses as fast as a Canon body could do. The image stabilization feature works too if the lens has it. The bad news is that it only works on Canon EF lenses made after 2006. There’s another drawback, too, in that it tends to drain the camera’s battery a lot (although the adapter has the ability to disable some features to address this issue.) Metabones T Smart Adapter Mark IV for Canon EF or Canon EF-S (crop sensor) lenses: USD $399 http://bhpho.to/1U2HHsk
TIP: There’s also the recently announced MC-11 adapter from Sigma which is rumored to do an even better job at autofocusing and mimicking a native E-mount lens than the Metabones adapter, however it ONLY works with Sigma brand lenses that have the Canon EF mount. (Another variety only works with Sigma SA mount lenses.) So if you have a genuine Canon lens this option won’t be for you. USD $249 at B&H: http://bhpho.to/1Un2PYE . |
There’s also one from Kipon which supports AF and has a slot for a neutral density filter built in. $428 at http://bit.ly/23jk0xh .
Fotodiox offers one for only $100 that performs moderately well in poor light: http://bhpho.to/1FHxudd Here's a video showing off its AF abilities: https://vimeo.com/135978162
Viltrox VILTROX EF-NEX II Canon EF Lens To Sony NEX Cameras USD $85.99, http://amzn.to/1LiWw0x. There are user reports that "not all Canon lenses work" but no specifics have been compiled. David Kilpatrick of f2 Cameracraft fame verifies that phase-detect AF points work with this adapter.
Commlite Auto-Focus Mount Adapter EF-NEX for Canon EF to Sony NEX Mount $75.66 A detailed list of compatible lenses appears on the sales page. David Kilpatrick of f2 Cameracraft fame verifies that phase-detect AF points work with this adapter. http://amzn.to/1xTHxnc Here's a video showing how well the AF works with this adapter: https://vimeo.com/135981179
Most of the other Canon EF adapters out there don’t have the guts (literally) to drive autofocus, and so your fancy EF lens will be a manual focus affair (and f/stop adjustment will either be impossible or via an iris within the adapter itself).
Before Canon switched their entire SLR camera line to the EOS mount in 1987, they used the manual-focus FD mount. Being backward-compatible with earlier lens mounts such as the Canon FL, FD mount lenses were in production starting with the Canon F-1 in 1971 and continuing to 1990 with the Canon T60 (the last camera to offer the FD mount).
Novoflex Adapter for Canon FD Lens to Sony NEX Camera $211.99 http://bhpho.to/1i1A4g5
Metabones adapter USD $99 http://bhpho.to/1KV8Civ
Then there’s this very inexpensive one from Fotodiox for only USD $28.95 which seems to get high ratings: http://amzn.to/1VxYLqX
Canon also made an R-mount camera lens for their very early Canonflex SLRs. Regretfully there are no known adapters for the Canon R-mount lenses.
