Nikon has now added a countdown clock to its launch microsite, and it's counting down to 12 midnight ET on August 23.
In a press release by the company: "In anticipation of Nikon’s introduction of the next generation full-frame mirrorless camera and Nikkor lenses.
According to Nikon, “the new mirrorless camera and NIKKOR lenses that are in development will enable a new dimension in optical performance with the adoption of a new mount. The system is the result of Nikon’s unsurpassed optical and manufacturing capabilities gained through more than a century of imaging expertise.”
It added that the camera is "the future of optics and imaging."
The shift to a new lens mount is no surprise, as this provides Nikon's engineers with a blank canvas to work with.
