I've to admit that I have a soft spot for Zenitars ;-)

The 60/2.8 is slated to have an electronic aperture control, at long last. Wondering what took them (us) so long, but it's a good thing that the company (which is actually a part of a huge technology conglomerate) is finally stepping away from just riding the coattails of the old Soviet-era designs (which never seemed that good anyway), rehashing them over and over again.

I also think there were a few fast things, too, like 50/1.2 and 85/1.4, for E-mount, a couple of years ago. But frankly until they get AF I won't be interested.

What is public status of every mount?
As far as I know
L mount - open standard
4/3   - open stadart
FE - open standart
RF - ??? no idea
Z - ?? no idea
------------
Lets say I'm Sigma, Tamron , Tokina, Chinese startup or Russian optics manufacturer. Do I have access to current RF/ or Z specs? Am I equal member in such aliance? Can I influence future development of the standard?

You forgot Fuji-X mount. I think they opened it up recently to some manufacturers at least (Tokina, Viltrox), but I'm not sure whether it's publicly open.

Thanks for addition.

Yes, it is super odd for the latecomers to insist on a closed system.

That being said - the fanboys insist that the RF protocol is basically identical to EF.

So did I, or we, miss seeing the Zenith 50mm F0.95 lens ........ for the Sony E mount ?? .......... thus I dug out a review or at least a partial one .... as it was curtailed due to obvious flaws ......

https://phillipreeve.net/blog/quick-revi...mm-0-95-e/

....... the bokeh is also dreadful .....


.... let's hope the macro does substantially better !!

Canon's RF is not the same as EF, a much faster and extended protocol. The cameras are EF backward compatible through the mount.

Another one - a 58mm f/1.9 - fairly huge for what it is I'd say

The lens elements are very recessed.... Looks like a Canon 50mm f1.8 with old macro style "integrated hood" extended barrel design.
