It looks like Nikon’s compact mirrorless camera has leaked its lens mount and sensor mount onto the web. Based on this image, it’s clearly not an F-mount camera – so you won’t be using existing Nikon lenses on this camera (without an adapter, that is). Additionally, the sensor looks smaller than APS-C format.
Some members of the Xitek forum (where the image leaked) claim that this is a compact camera image sensor like the Pentax Q system. That would put it in the 1/2.3″ or 1/2.5″ range, which would likely result in a camera that few take seriously.
However, eagle-eyed commenters over at Nikon Rumors examined the screw head diameter in comparison to the sensor size and estimate that the sensor is around a 2.7x or 2.8x crop factor. This would mean that it is still smaller than the Micro Four Thirds sensors, but larger significantly larger than your typical compact camera.
The above image somewhat corroborates the design implicated by previous Nikon patent applications.
Is this the kind of compact, interchangeable lens camera you’ve been looking for? Or is a sensor this small still out of the question for you?
