Canon Talks 250mp APS-H Image Sensor at ISSCC

By Canon Rumors | February 12, 2016 | Canon DSLR Rumors

Canon is once again talking about their 250mp image sensor that they showcased at the Canon EXPO back in September. This time, they’ve presented a paper at the ISSCC 2016 Conference (All About Sensors).

Harvest Imaging has this to say about what Canon presented:

Hirofumi Totsuka of Canon presented a 250 Mpixel APS-H size imager : 1.5 um pixel pitch (4 sharing) made in 0.13 um technology node.   The device is consuming 1.97 W at full resolution 5fps.  An interesting build-in feature of this sensor is the following :  ALL pixel signals are converted by column SS-ADCs with a single ramp, but in front of the ADC, each column has its own PGA that can be switched to 4x or 1x gain, depending on the signal level.  So when the pixels are sampled, a first check is done to look whether the signal is above or below a particular reference level, and then the right gain of the PGA is set to 1x or 4x.  Simple method, but I think that the issues pop up in the reconstruction of the signal at the cross-over point between the two settings of the PGA.

This sensor does not mean that the APS-H sensor size is returning. We imagine that whenever the 250mp sensor comes to market, it will be in a full frame application.

We’re told Canon will let us know something at NAB 2016 in Las Vegas about the Cinema EOS C500 Mark II, though there may not be an official announcement.

We reported back in 2014 that Canon was gearing up to develop an “A” camera to compete with current market leader ARRI, and that the C500 replacement would like fill that spot.

We first reported back in April of 2015 that Canon was going to go above 4K in the Cinema EOS C500 replacement, and that such camera would be announced in mid 2016. Canon themselves confirmed this by letting the world know at Canon EXPO in September that they were working on an 8K Cinema EOS camera.

We expect to hear a lot more about the Cinema EOS lineup in the coming weeks.

Sigma Teasing New Faster Than f/2.8 Zoom?

By Canon Rumors | February 11, 2016 | Third Party Lenses

The Sigma Austria Facebook page is teasing a new lens to be unveiled on February 23, 2016. By the shape of the outline, it looks like they may be teasing a telephoto zoom lens faster than f/2.8.

If you have more information than that, please let us know.

The world is waiting for Sigma to release an 85mm f/1.4 Art series lens, and it looks like we’ll have to wait a little while longer.

Thanks Alexander
