Nikon Patent for a Nikkor PC-E 19mm f/4 Full Frame Mirrorless Tilt-shift Lens

Nikon has filed a new patent in Japan.  The new patent describes a Nikkor PC-E 19mm f/4 tilt-shift lens aimed at full frame mirrorless cameras.

This is the second Nikon patent for a full frame mirrorless lens – the first one was for a 28-80mm f/3.5-5.6 VR lens.

Below is a 2014 quote from Toshiaki Akagi (Department Manager in Nikon Design Department):

“We know that there is a certain body of demand for larger sensors in mirrorless products. Although we already have the 1 inch sensor in the 1 System, we don’t want to deny the possibility of future large-sensor mirrorless cameras. So maybe if there is enough demand we may be able to provide another type of mirrorless camera with larger sensors. This is one of the solutions.”
