Canon Mirrorless Information [CR1]

Canon Mirrorless Information [CR1]

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.

Lenses
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.

Body
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”.

EF Lens Adaptor
We have posted a couple of patents in the past about such an adaptor. You can view them here and here.

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.

Canon Develops World’s Largest CMOS Sensor

Canon succeeds in developing world’s largest CMOS image sensor, with ultra-high sensitivity

TOKYO, August 31, 2010-Canon Inc. announced today that it has successfully developed the world’s largest*1 CMOS image sensor, with a chip size measuring 202 x 205 mm. Because its expanded size enables greater light-gathering capability, the sensor is capable of capturing images in one one-hundredth the amount of light required by a professional-model digital SLR camera.

At 202 x 205 mm, the newly developed CMOS sensor is among the largest chips that can be produced from a 12-inch (300 mm) wafer, and is approximately 40 times the size of Canon’s largest commercial CMOS sensor.*2

In the past, enlarging the size of the sensor resulted in an increase in the amount of time required between the receiving and transmission of data signals, which posed a challenge to achieving high-speed readout. Canon, however, solved this problem through an innovative circuit design, making possible the realization of a massive video-compatible CMOS sensor. Additionally, by ensuring the cleanest of cleanroom environments during the production process, the sensor minimizes image imperfections and dust.

Because the increased size of the new CMOS sensor allows more light to be gathered, it enables shooting in low-light environments. The sensor makes possible the image capture in one one-hundredth the amount of light required by a 35 mm full-frame CMOS sensor, facilitating the shooting of 60 frame-per-second video with a mere 0.3 lux of illumination.

Potential applications for the new high-sensitivity CMOS sensor include the video recording of stars in the night sky and nocturnal animal behavior.

Through the further development of distinctive CMOS image sensors, Canon will break new ground in the world of new image expression, in the area of still images as well as video.
