Their slogan: “TRAVEL OF LIGHT” as well as a very dark video do give a hint, that we can expect exceptional low light capabilities.
Roger Johanson extracted the most interesting part of the video, slowed it down and brightened it up:
As you can see the new camera looks a bit like a Sony A7 series but with a bigger lens mount and a bigger grip. This may will be a big advantage compared to the various mirrorless cameras available, as those are often equipped with a to small grip for bigger hands.
Based on past Nikon announcements we’d expect the next Teaser in around 2-3 days.
