Nikon entering the frame with the Z7 has opened the race for full frame mirrorless video cameras, fortunately Nikon produce a lot of full frame F mount lenses with an adapter. The new camera uses a new Z mount which I assume is more dedicated electronic lens. The two points I don’t like about the Z7 is the use of expensive XQD cards and it only films up to 4K 30p and not 4K 50p as seen on the Panasonic GH5.
Panasonic are seemingly intending to sport a full frame GH5 type camera at Photokina later this month but not with a Leica SL mount I am glad to report.
Panasonic don’t produce full frame (FF) lenses, yet, but assuming they do go down this road I predict you will see at least 3 new FF Panasonic lenses at the time of launch.
The EVA large sensor camcorder uses the Canon mount but I think this would be hard for Panasonic to swallow to give Canon an open lens market again.
I do hope we are finally going to see some decent servo zoom glass for mirrorless cameras as this has been badly neglected in recent years.
Canon are also producing the full frame EOS R camera with what looks like a small touch bar (zoom control) on the back full details on the 5th of September.
