We know Nikon is about to re-enter the mirrorless camera market in a serious way, and we might have some of the details. Nikon Rumors reports that Nikon plans to introduce two full-frame mirrorless cameras next Thursday, August 23rd. The cameras are called the Z6 and Z7, according to the rumor, and they would be introduced alongside three lenses designed for the new system.

The Z6 and Z7 will reportedly be differentiated in the same way Sony differentiates its A7 and A7R models: the Z6 will have a 24-megapixel sensor and be designed to handle faster, lower-light shooting, while the Z7 will have a 45-megapixel sensor for capturing far higher-resolution images.
