Oh my.... NOW you're F*d Exmor users...

TOKYO, March 4, 2013—Canon Inc. announced today that the company has successfully developed a high-sensitivity 35 mm full-frame CMOS sensor exclusively for video recording. Delivering high-sensitivity, low-noise imaging performance, the new Canon 35 mm CMOS sensor*1 enables the capture of Full HD video even in exceptionally low-light environments.

The newly developed CMOS sensor features pixels measuring 19 microns square in size, which is more than 7.5-times the surface area of the pixels on the CMOS sensor incorporated in Canon's top-of-the-line EOS-1D X and other digital SLR cameras. In addition, the sensor's pixels and readout circuitry employ new technologies that reduce noise, which tends to increase as pixel size increases. Thanks to these technologies, the sensor facilitates the shooting of clearly visible video images even in dimly lit environments with as little as 0.03 lux of illumination, or approximately the brightness of a crescent moon—a level of brightness in which it is difficult for the naked eye to perceive objects. When recording video of astral bodies, while an electron-multiplying CCD,*2 which realizes approximately the same level of perception as the naked eye, can capture magnitude-6 stars, Canon's newly developed CMOS sensor is capable of recording faint stars with a magnitude of 8.5 and above.*3

Soooo when does this move to DSLR tech?

Probably won't translate to DSLR since the pixel size is so large or not very soon.

Uh, yes it will. It's a 35mm sensor.

It's a HD-video sensor, which means it will show up in VIDEO cameras (it doesn't have the number of pixels of current full-frame dSLR STILL sensors), but still....

Incidentally the noise-reduction technology they came up with (which is the limiting factor for high ISO recovery) appears to be something that would immediately translate into dSLR-density full-frame sensors as well.

When they are able to figure out how to make the pixels smaller.

35mm sure....but would you want a brand new FF DSLR with this sensor that has a say 1920x1200 resolution?

No, but I would want a FF dSLR that had the high-iso noise reduction they figured out in THIS sensor in my dSLR, which would further push the capability to capture images with a low noise profile, and I might be VERY interested in a video camera with a HD sensor that can capture at 0.03 Lux!

But you just said "Oh duh it's a 35mm sensor" but in order for it to work in a DSLR the pixel size will have to be smaller. When the pixels become smaller and more densely packed, you can end up with more noise. The sensitivity part could also be due to the size of the pixels where when reduced loses the effectiveness. You simply can't plop this technology into a DSLR sensor and expect it to work.

Hmm.. This seems to buck the current web lore. So if I'm understanding it right, big pixels are bad.

I'm guessing that the writer meant to say that though noise may increase, so does signal so the S/N does not.


Not sure why, but call me JJ.
I used to hate math but then I realised decimals have a point.

Somehow I don't think there will be a big market for 3 MP cameras, except maybe among coal miners.

The market is huge for industrial and security uses. Pretty much every public building has at least one camera, some have hundreds. They could make a killing in Vegas where each casino could have thousands.

Mega picks and very large shovels presumably..?

Note that Canon already have quite good noise handling in their current sensors. The issue Canon have, is to be able to balance the reading between neighbour pixels.

And the article about the new sensor specifically says that the noise improvements of this new sensor is to reduce the amount of noise that happens when you read out data from very large pixels. So that would indicate that it may not be applicable for a sensor for still images, where we wants much more (and smaller) pixels.

Does not get us any nearer a Canon answer to the D800/D800E. I wish Canon would forget this obscession with video and start thinking seriously how they intend to beat Sony and Nikons Exmoor sensor and processor.

Gee. Not sure if you know. But DSLR is only one of many branches Canon works with. Why should they ignore video just because they currently have a fight on their hands to find a work-around for the Sony patent about balancing channels? You think Canon gets more resources to solve the noise issues, if they ignore their other branches and take an economic hit there?
