Here is leaked photos of Canon mirrorless

EF-M mount,22mm STM lens
The front element looks way too small for a retro-focus 22mm lens. The length of the lens is thicker than the body. assuming the body is about 22mm ( body thickness of NEX). Therefore the 22mm must be a retro-focus lens. Also if the body thickness is 22mm, then the lens mount looks like is about 80mm. That is a lot bigger than the EF mount (65 mm). Also the lens says EF_M. This term is created by one of our poster. Does he really have a ESP??? I think some one created the picture. I do not believe it is the real thing.
The name Mr. Pink sound too close to MR. Plank
Err.. the outer diameter (filter size) is only 43mm. It says so. Nowhere near 80mm This is a lot smaller than an EF lens.
Thats not the outer diameter, thats the filter thread size, which is the inner diameter of the depressed area around the front lens element. The filter thread size has nothing to do with the lens mount size, and therefor has nothing to do with the size of the sensor. I have a hard time believing they would call the lens EF-M, and not use the same bayonet mount as all other EF based lenses.
BTW, the EF bayonet mount itself is 54mm in diameter, not 80mm:
