A bit of information
With Canon's expected foray into the mirrorless segment just around the corner, a bit more information has started to flow.
We're told the new camera is in fact a new mount, I think most expected this. The camera will launch with at least 2 lenses and an EF adaptor. One lens will be a wide angle “kit” lens as well as a telephoto lens.
No word on whether or not the EF adaptor would also adapt EF-S lenses, though I would hope it did.
It is also suggested that the new primes that Canon has announced and released (24, 28, & 40mm) are the first in a series of small prime lenses meant to work well with EOS EF and the mirrorless camera.
Information about the body itself is pretty vague. It's still suggested the camera will use the 14mp CMOS G1 X sensor. A “good” ISO range and “average” video performance. A video focused camera could be “in the future”.
Northlight has posted a cool little diagram showing the size of the EF adaptor in comparison to the new EF 40 f/2.8 pancake.
