Canon Mirrorless Information [CR1]

Another advantage for Mirrorless is truly awesome ultra-wides with pin sharpness to the corners is possible. Less retro-focus designs. 8)

I'v heard this alot but so far on digital the reality doesnt seem to match up, existing ultrawides on the NEX almost all perform poorly and the options on m43 are neither shorter nore cheaper than you'd expect from an SLR.

Well, I was thinking about the Good contax/Zeiss lenses for m43 or leica M mount.

Zeiss does not make lens for m4/3. They are for FF only. So are the Leica M mount lenses. If you look at the rangefinder lenses, both Leica and Zeiss are Retro-focus design for anything wider than the 28mm (FF). That is due to the sensor require close to vertical (60 degree minimum??) incident angle. After multiplication factor, you will not have a ultrawide from either manufacturer.

Zeiss does make leica m mount lenses [ZM] which of course can be easily adapted to m4/3 or NEX cameras. Voigtlander also makes a couple of pretty wide M mounts lenses.

There are also adapters for m4/3 and NEX to mount the old Zeiss Contax G lenses

He is looking for ultawide lenses on M4/3. Anytime a FF lens is used in a 4/3. the effective focal length will be doubled up. whether it is M39, Leica M mount, Contax G, Ef, Fl , Fd, any lens you can name will be the same effect.

a 12mm m-mount Voightlander on the APS-C Sony NEX maybe isn't super wide @ 1.6x (not 2x), but not bad. Not much help with the m4/3 system though. Small sensors are just wide angle killers. Still dreaming about a compact FF landscape camera.

Why does it HAVE to be smaller? Just remove the mirror mechanism. You don't have to reinvent the wheel, just sack the mirror.

It's hard to describe the form factor I was looking for, so Samsung created it in the NX20 Mirrorless Wi-Fi Digital Camera. Granted, the Wi-Fi is "gimmicky" to me. It looks like a full frame DSLR, but doesn't have a mirror. So... it looks like Canon has taken the track of a small body for now. Maybe the next version will be based on the 5D frame and retain the EF/EF-S mount. :
