2 mounts for still cameras, A and E. How many does Canon have?

This whole concept is for fixed lens cameras, even according to their own propositions.

that isn't so obvious to me.

Canon has technically speaking 3 mounts, but if I'm not mistaken they are all physically (dimensions and electronic contacts layout) the same. what changes is flange (EF-M against the rest) and in case of Canon proprietary EF-S lens - artificial mechanical obstruction - if you take any third party APS-C lens for Canon it fits normal EF camera and works on them (i.e. Tokina 12-24 or Sigma 18-125 to name the lens I tested myself).

Sony as such has 4 different options: FF or APS-C and mirror(ed) or mirrorless. although they are to some degree interchangable

but my point wasn't as much about the total amount but about the fact that Sony had introduced quite a lot of incompatibility issues in a short period. if you make a timeline of Canon's AF system mounts then you get:

EF - 1987

EF-S - 2003

EF-M - 2013

since the takeover of Konica-Minolta in 2006 Sony has added 3 new mounts. that's 3 in 8 years compared to 3 in 27 years and explains quite well why people are confused with Sony offering and where the "give us another mount, Sony" jokes come from.

Sony has two mounts:
A-mount: The SLR mount
E-mount: The Mirrorless mount

They also have FZ mount.

Sensor size has nothing to do with the mount.

Nobody cares about mounts or sensor sizes really. What people care about is lens system. If all Sony E lenses (and 3rd party lenses for that system) covered FF image circle from the start, introduction of FE would not be as bad. As it stands, Sony supports 5 lens systems, and understandably unable to support even one of them properly. For comparison, Olympus and Panasonic support half a lens system each. No wonder it has become the best, most complete crop system in no time at all.

FZ-mount is not for use in Alpha system (stills cameras). If you want to include video cameras, I am sure te count will go up for Canon from three to something else, no?

As for APSc vs FF lenses, why is it that people think this is unique to Sony?
Canon has EF-S and EF lenses
Nikon has DX and FX lenses
Sigma has DC and DG lenses
Tamron has Di II and Di lenses

A reason you build APSc lens lineup alongside FF lenses is that you often have to maintain a difference, especially with zoom lenses: how many FF lenses can you count that cover 16-50mm, for example?

The other issue is pronounced anxiety about Sony FE lenses, on a system people can use lens from pretty much any mount. And how long has it been since the two FF cameras have been made available? A year? Two?
