Canon system to M43

It seems everyone is divided. But I think I will go down the 4/3 totally route. I will miss the 85 1,2 though!
 
The only clincher for execution is that I'm pretty sure canon will pull a mirrorless out of their hat latest September... But what lens system and sensor size?

:schtum: ;)

have you seen the new Canon 40mm EF pancake lens?

have you seen the new Canon 40mm EF pancake lens?

Yes I have. As you say it's an EF lens with a flange focal distance of 44mm (from lens mount to sensor). Now if Canon made a mirrorless system that fit EF lenses directly, it would basically have to be as deep as a camera with a mirror to maintain the same 44mm distance.

There's a reason why micro 4/3 lenses don't fit 4/3 cameras but the other way around works with an adapter. The flange focal distances are 19.25mm and 38.67mm respectively.

Thus it doesn't make a lot of sense for Canon to make a mirrorless camera with an EF mount as half the point is to get very small bodies without the mirror. The other part of the size equation (lens size) depends on the sensor size. Have you seen the size of Sony NEX lenses compared to the bodies...

I would LOVE to see Canon introduce a full-frame mirrorless camera but I'm not sure how much love that would see from the normal consumer segment because of the lens size & cost :)

In the real world, Canon just put out a new 14MP 1.5" CMOS sensor (18.7 x 14mm) in the G1x pro-"compact". It's 20% smaller (in area) than their APS-C but bigger than the 4/3 sensors. It's also 4:3 compared to 3:2 in their DSLRS. So the height is almost the same as APS-C but the width is reduced. From dpreview:

I think this will be the sensor that will show up in the first Canon mirrorless. It would allow smaller dedicated lenses than Sony Nex system (which is 3:2 APS-C so needs a bigger imaging circle) while allowing EF-S and EF lenses to work with an adapter at close to 1.6x APS-C crop factor (works out to 1.8x).
