Nikon's plans for a small interchangeable lens camera may have garnered support on Friday as a tease from an anonymous source hinted at what might be its mounting system. What appears to be a dry run for a presentation obtained by Nikon Rumors shows slides with "Nikon Q" and a stylized logo underneath. Another shows the Q over the lens area on the darkened frame of what looks like a pro camera, implying a new lens format other than DX or FX.
