You wait for years for a full-frame mirrorless camera to show up from the most dominant brands in photography, and then two show up at once. Right after Nikon announced its first serious step into high-end mirrorless with the Z7 and Z6, it looks like Canon’s own effort is imminent. Leaks from Japanese website Nokishita have revealed images of the camera, its spec sheet, and details on the initial lens lineup.

The camera is apparently called the EOS R, and looks a lot like a slimmed-down full-frame DSLR. The controls appear to be tweaked somewhat, with unmarked dials (not PASM) and a curious left-right switch on the back. The screen is fully articulated, and there’s a secondary information display on the top. The full-frame sensor is reportedly 30.3 megapixels, which would put it between the Nikon Z7 and Z6.

The first four lenses are a 35mm f/1.8, a 50mm f/1.2, a 28-70mm f/2, and a 24-105mm f/4 kit lens, with the latter three bearing the red ring of Canon’s high-end L series. That’d put Canon ahead of Nikon if all four are available at launch; Nikon initially only has a 35mm f/1.8, a 50mm f/1.8, and a 24-70mm f/4. Canon is also launching three EOS lens adapters, including an option with a control ring and another with a drop-in filter mount.

According to Canon Rumors, all of this will be announced this Wednesday, September 5th, so we shouldn’t have long to go to find out the full details. One thing’s for sure: the entire camera industry is now serious about mirrorless.
