After years of rumors, Nikon has finally confirmed that it’s working on an all-new mirrorless camera system based around a full-frame image sensor. The company has given very few details, but we know the system will use a new lens mount and thus require new lenses, though an adapter for F-mount SLR lenses will also be available. (It’s unclear whether this will offer features like autofocus.)

This will be Nikon’s second line of mirrorless cameras after the Nikon 1 series, which launched in 2011 and was recently discontinued. Nikon 1 used small 1-inch sensors and unconventional controls, with an anemic lens range that mostly consisted of slow zooms, meaning image quality was usually closer to a point-and-shoot than a DSLR. There was an F-mount adapter available, but the sensor size meant that focal lengths were cropped to extreme degrees, turning all but the widest lenses into telephotos.
