According to Nikon Rumors, the upcoming full frame mirrorless from Nikon will have a new mount, dubbed the “Z Mount”. That name could change before the announcement.
Specifications of the new mount:
- Designed for full frame mirrorless cameras
- External diameter: 49mm
- Flange focal distance: 16mm
This is where Canon could really have an advantage. If they can somehow make the 130million or so EF lenses compatible with a full frame mirrorless without an adaptor, they won’t have a hard time getting Canon DSLR shooters to add a full frame mirrorless to their kit.
