The premise is that both models should be full-frame, but Nikon Rykter has no confirmation at the front. One will apparently be 24-25 MP while the other will be 45-48 MP. The body looks like Sony's a7 camera, but Nikon focuses on better ergonomics and better grip for these devices. They boast 5-axis body stabilization, 9 fps and a new 55 mm mirror-free mounting that allows f / 0.95 lenses.
The cameras will accept both XQD and SF Express memory cards. There are three lenses just outside the line: 24-70mm, 35mm and 50mm. The Premium 45 MP model will be around $ 4,000 / € 4,000, and comes with 24-70mm kit lens. The 25 MP camera will be in $ 3000 / € 3000 and also comes with an objective.
None of this has been confirmed directly by Nikon, and Nikon Rumors makes it clear that any of these Specifications may not be accurate. Nevertheless, it gives interested buyers who have been waiting for a Nikon reflex camera, hoping that these devices will actually come soon.
