https://nikonrumors.com/2018/06/02/nikon-has-a-new-noct-trademark-for-cameras-and-lenses.aspx/Things are starting to become clear...
Nikon has apparently chosen their traditional forte, the PJ domain, as the target application for their first FF mirrorless system.
My guess is that it is going to be a mini-D6 with unique lenses for a best ever low light shooting capability thanks the combination of the sensor and uniquely bright lenses.
Based on their recent track record in terms of lens design, we can expect to get a remarkable combination of top notch technical performance and bokeh to die for.
Venturing further in the guessing:
- Z mount with open specs
- 24mp, ISO fully usable up to 25,600, 16 bits pipeline
- New EVF part with low power mode leveraging natural light at day time to enable extended battery life
- the new large opening mount will enable fully circular oof specular highlights with portrait lenses
- 4K video over the full sensor at 120 im/s - ability to downscale video in camera to full HD in lower bit rate for quick sharing over the internet
- raw histogram
- fully water proof body suitable for underwater shooting down to -5m with special lenses (one in roadmap at announcement)
- IBIS
- best in class integration with smart phone (snap bridge 3.0)
- open OS accepting third party in camera apps through new dedicated store
What part of that makes sense?

Cheers,
Bernard
