arcticlightphoto Posted July 5, 2014 Share Posted July 5, 2014 For folks who have Canon EF lenses, all that's needed is a high quality (Metabones etc.) EF to E-mount adapter to get full frame. A Speedbooster gets the GH4 to S35 (full frame not possible). The 720p 120fps S35 crop on the A7S could be full frame with a Speedbooster. --- Just one remark, currently there exist noe Metabones Speedbooster for Canon EOS -> M43 (GH4). Form what I hear, Metabones are struggling with the electronics to make AF work. Some cheap focallength reducers "speedbooster-copies" are available on ebay, though fully manual, and optics are probably not as good as Metabones. Does the A7S support only 720p in S35 mode? Or also 4K and 1080p ? Ole Quote Link to comment Share on other sites More sharing options...
