A quick update on my last post about the rumored new full-frame mirrorless Z-mount from Nikon: the measurements I reported caused some confusion in the comments section – my understanding is that the external diameter of 49mm is the actual mount opening, the entire external diameter of the mount is going to be 65.4mm (just received this update):
- Mount diameter (opening): 49mm
- Total diameter of mount: 65.4mm
- Flange focal distance: 16mm
The top graph by Eric Calabros shows a comparison between Nikon Z-mount and Sony E-mount: the Z-mount has more than 6 degrees advantage over E-mount (important for wide angle and fast lenses).
