Set advanced mode on Metabones adapter V0.57 (Mk IV) - latest firmware Tried Canon 35mm F2.0 IS (new-ish one with STM AF) Even with AF responsiveness and speed both set to their fastest on the A7R3, performance is dismal compared to the Sigma lenses on the Sigma MC-11. It's laggy, unsure, unreliable and noisy. This is not in bright sunshine, it's inside. Maybe it is better in very bright light? But the Sigmas were in dim light as well and did much better. It's just about usable for a slow focus rack in bright light, but I wouldn't challenge it with anything else... Better to swap out the lens for a Sigma and MC-11. Now in STILLS mode with Advanced mode set on Metabones... Oh dear. It's even worse. C-AF seems not even to use phase-detect AF and hunts around never really acquiring focus with any certainty! Will do a bright light test tomorrow but doubt it is any better. I have also tried Metabones for video with Canon glass (both modes), it does not work properly, so I agree. These videos fool people mostly. Can use metabones in green mode for stills with center AF for stills for not to fast photos shooting. Landscapes are ok. The problem with Sigmas is that they make noise when your AF works hard e.g. sports. A lot of Canon glass also make quite some noise. The best lenses are Sonys, most of them are quite when AF for video. Quote Link to comment Share on other sites More sharing options...
