Opinion:I've always been dubious about purchasing the MB, I do not like hooks and I've never even used focal multipliers. I was convinced only because the offer I had found for Sony a7rII included the Metabones and the 1,4X. Rnrn I tried it for a few goals in almost a year and I can say that while there is no general rule , the better the Canon lens, and the better it works on the MB. The 70-200 f4 does not go very well, with the 300m f4 it's fine, even with the 1.4X. With the Tamron macro 90mm 2.8 pounds. It does not go with Aps-CrnrnInsomma, bring your lens and try it. When it goes, it's a great accessory, and if you're a former Canonist like me, you'll have saved a lot of money or you've got a lense kit that Sony does not have right now. Rnrn
Opinion:28senza have to use the appropriate button). rnrnIl famous "flub" of the edges personally have not seen it with the few lenses tested and also judging by the opinions of others, we do not know whether there is and how much is related to the adapter, the camera or vibration reduction system. Therefore I do not comment on the matter.
Pros:allows the use of EF lenses on Sony maintaining control of the diaphragm
Cons:Because frequent blocks, very high price, the AF becomes unusable
Opinion:The Metabones EF / NEX IV is one of the adapters Canon-Sony best known; It transmits all data to the camera lens and allows you to keep the automatic, although with limitations. The AF is slow to the point of being unusable (but this is already stated on the same site Metabones, so no surprise); The biggest problem I found is that with some lenses because frequent blocks, enough to make it unusable. In my case (A5100 Sony camera), it works quite well with the Sigma 8-16, while with the Canon 180 Macro 50% of the time the camera stops completely and the only way to restart it is to remove and re-attach the lens; the numerous firmware updates applied over time did not improve the situation (I eventually solved by replacing the 180 with a Canon Tamron 180 + adapter for Nikon Novoflex, with manual aperture ring on the lens). In conclusion, if you want to buy it before you do a little research on the web per ensure that it works well with the combination camera / lens on which you want to use!
