Nikon Lens Patent for APS-C Mirrorless Cameras

Nikon has filed a new patent in Japan for a kit lens for APS-c sized sensor mirrorless cameras. The new patent describes Nikon 18-55mm F3.5-4.5 lens.

This is a good sign that Nikon is preparing a mirrorless system with APS-c or full-frame sized image sensors which could be launched next year.

Another Nikon lens patent for full-frame mirrorless cameras showed up on the web last year. More details about the Nikon 18-55mm F3.5-4.5 lens can be seen below.
