It was super cold here this morning. I had to put slippers on to get the paper.

I hope this one will go to production.
Agree but want it to rival the Nikon 14-24 for IQ
I'll settle on 'well justifies an upgrade from the Sigma 12-24mm F4.5-5.6 DG HSM II', which I think will have to be the same as 'rivals the Nikon 14-24mm's IQ'.
I think Rogers's definition of a plastic vs. a metal mount differs from how most people think about those terms. For most of us, we're talking about the bayonet parts - the 'teeth' that lock into the mount on the camera.While I agree with you, I note that the article was provoked by the current furor over the Olympus lens that has a metal bayonet mounted on a plastic base like most lenses ( as Roger notes) and that THAT revelation of the use of plastic in a critical part is sparking the rage on the nets.
The EF-S 18-55 on the left has a 'plastic mount', the EF 17-40L on the right has a 'metal mount'. Very few of us disassemble lenses, so we have no idea what's behind that mount surface. Roger is talking about how the screws that that attach that visible surface piece to the lens are connected - do those screws go into metal screw-holes that are attached to the frame of the lens, or are the screw-holes plastic?
'Plastic' can be quite strong, so for a 'light' lens (most lenses under 100mm, with the exception of the 'magic cannonball' 85L), I agree with Roger that I wouldn't expect any issues, and 'professional' could apply. However, for the bayonet 'teeth' of the mount, plastic wears down more easily than metal (vs. the screw-holes, which aren't subjected to routine 'wear'). That means a lens with a plastic mount (as I'd say is the common definition pictured above, not Rogers's use of the term), would be able to tolerate fewer mount/unmount cycles than a lens with metal bayonet teeth. Since a professional lens would be expected to last years and most 'pros' own several lenses and change them frequently, it makes sense to associate a metal mount (as pictured above, regardless of how it's screwed in) with 'professional' build.
Kind of hoping for a new chip that competes with the Sony/Nikon overall quality.
All cameras shake, it's just this one is super light.
Big DSLR announcement, hmmmm. Could they make a camera with an EF mount? Just think, all the sigma lenses sold to canon users would now work on it along with the canon lenses too, it would be a Trojan horse coup d'e'tat
I still preferred the colors out of my 5Dc than my MK3s. I skipped the mk2 series because it wasn't worth upgrading for me.
I never understand comments like this. It is digital, why not profile your camera to get whatever "look" you want from it? The free with every Canon camera ever Picture Style Editor is a remarkably powerful program that you can even edit and save then upload your "look" to the camera Picture Styles menu, and every shot with that style comes out looking exactly as you'd like it to.
Finally a 50mm with a decent AF system?
The 135mm f/2 L IS would be lovely for weddings!
