In an interview with French photography blog Mizuwari, Nicolas Gillet, director of marketing and communication for Nikon France, revealed a number of interesting tidbits regarding Nikon’s new Z-mount and the new opportunities it affords Nikon’s optical engineers.
According to Gillet in the transcribed interview, Nikon optical engineers have calculated that the Nikon Z-mount is theoretically capable of supporting autofocus lenses with apertures as large as F0.65.
This comes as a stark contrast to the physical F1.4 limitation of the Nikon F-mount.
Gillet also explains the Noct-Nikkor 56mm F0.95 is a testament to what glass Nikon could, in theory, create for its new full-frame mirrorless mount, but makes no mention of future lenses not already on Nikon’s lens roadmap it unveiled alongside the Nikon Z7 and Z6 launch event.
