We've already heard plenty of talk about Nikon's forthcoming entry into the world of mirrorless cameras, and it looks like we now have our first real peek at the actual goods. Unfortunately, it's just a look at the mount, not the whole camera (said to be codenamed X810), but it does appear to be the real deal (and was apparently removed from the Chinese forum it surfaced on, Xitek, at Nikon's request). Details on the camera itself are otherwise still fairly light, but it certainly sounds like Nikon has some grand plans for it -- the company's previously boasted that it wants to create a whole new market.
