about Sony 24/1.8, I don't think it is very different from 22/2, other than three things: size, price, and a silly Zeiss brand.

At this point we don't know if the Canon 22/2 can take on Leica 24/2 Summilux-M. We do know that the Sony 24/1.8 can. So, it might be more appropriate to say that similarities between Canon 22/2 and Sony 24/1.8 begin and end with proximity of focal length and maximum aperture in the spec sheet.

The Zeiss isn't THAT incredible, in terms of resolution. It's pretty good, but isn't fantastic at infinity, and the Sigma 30 is better at all comparable apertures.

And where can I see this?

Well, I've owned both lenses, but here is a pretty reputable test:

It may be reputable test when considered individually, but you can't go around comparing MTF50 numbers between lenses unless the same camera is used. I don't think you'd pick Sigma over Leica Summilux just because LensRentals found it to be superior.
