Hell, I\'m anxious to see what you have to say about it when adapting three of Canon\'s best lenses; I assume that a Metabones glassed adapter is in order?


Well if it allows full AF and IQ isn\'t affected, hell yeah. Lot of water to pass under the bridge first. One thing I hadn\'t realized that is a downer is the A7R gets the lesser AF, basically same as NEX 7 which isn\'t that good. It\'s the A7 that gets the hybrid AF. Won\'t matter much for landscape, architecture and macro, but it\'d nice to use the Sony for wildlife now and then.


I\'ll wait for your review- but I expect even the best Metabones adapter to have the same drawbacks that using a teleconverter would- namely, slower AF, reduced sharpness, and reduced aberration control.

And with the A7r\'s CDAF, I don\'t expect that to improve; even if the SLT adapter would work, it would put more glass between your lenses and Sony\'s sensor.

Color me guarded, but hopeful .


so long as the mount is flush why would the metabones adapter hurt IQ at all? (granted so long as it is flush may be a big \"so long as\") It doesn\'t have glass in it like a TC.


He is talking about the speedbooster from metabones I think. Only \'glassed\' adapter I can think of.

Obviously you don\'t need glass to convert a FF or MF lens to an E-mount camera.
