Quote:In dave's case he already owns a state of the art APS-C and camera of the year 2016 and wahtever prices his D500 might win. And since the metabones adapters are great but do not allow AF or even EXIF data transfer, there's no advantage in terms of AF.
More than that, the D500 has AF calibration, so in terms of AF-speed and tracking with 3D AF-C there's practically no competition in mirrorless bein superior than the Nikon.
Well, I don't know about Nikon, but the EF-MFT Metabones adapters do allow IS, AF, and pass on Exif information. It works with any of the EF lenses I have used so far, like 85L, 135L, 100-400L IS II ....
AF speed is as fast as with these lenses used on my 5D II, if not faster - haven't had an opportunity to compare it with a newer Canon body yet, and as I am not a sports shooter, or BIF person, I haven't compared tracking, although almost anything will be faster than a 5D II with 100-400L .
Kind regards, Wim
