Canon has developed a new sensor with 20-stops dynamic range that’s good down to 0.08 Lux

Canon has developed a new CMOS camera sensor that offers a high dynamic range of up to 20 stops, with super high low light sensitivity. The LI7050 is a 1/1.8″ CMOS sensor is an impressive little beast, but this is just early days.
The sensor is quite small (measuring only 7.11 x 5.33mm) and captures only a mere two megapixels. It’s also a rolling shutter, not a global shutter. So, there is still a way to go before we might start to see this kind of tech in a full-frame camera, but Canon says it will go on sale to gear manufacturers as early as October.
Canon says that the new sensor captures FullHD colour video in environments as dark as 0.08 lux. For reference, one lux is essentially the amount of light a single candle puts out on a surface one metre away. That’s not a lot of light at all!
Despite the sensor itself being physically small, the low 2-megapixel resolution allows for a relatively decent sized pixel size, coming in at 4.1µm. This is only slightly smaller than the 4.35µm pixels found on the 45.7-megapixel full-frame Nikon D850 but significantly smaller than the 8.32µm pixels found in Sony’s recently released A7S III.
Still, it seems to offer extremely impressive low light performance, judging by the sample video above posted to YouTube by Canon Japan. They say it has a 120dB dynamic range – which means about 20 stops. This is a good 5 or 6 stops over most DSLR and mirrorless cameras available commercially today and would allow you to film interiors without blowing out the view through windows.
Looking at the outdoor scenes, though, it doesn’t look like it pulls the shadows up too well yet, so you’d want to expose for those and then drag the highlights down rather than exposing for the brights and trying to lift the shadows.
It’s an impressive feat. Now they just have to scale it up to larger sensor sizes, give it a rolling shutter and let it shoot 4K120 without overheating and we’ll be all set.
Canon says that samples have already begun shipping and will officially begin sales in late October.

That’s eyesight quality. Cool.
OK, I’ll start it: I’ll bet it is really capable of 40 stops of dynamic range and shooting full HD video in light down to 0.008 lux, but Canon being Canon they deliberately crippled it!!
Security systems for the first products, I assume
Military would like this too I’m sure
Nice for a webcam
Does it come with a fire extinguisher
Shaun Grohn would you have posted the same comment if sony developed this as everyone of their cameras in the past 8 years has overheated
Amarjeet Talwar don’t care what brand the camera is, users have to be critical of failures and demand better.
Should it be true it would be a major step forward. Stop ridiculing.

Wait so im not understanding. It’s a 2 megapixel sensor. So im assuming this wont have enough pixels for UHD+their stabilization right? No more than Full Hd? Or where am I wrong? Id love to see tech get this sensitive it lowlight but I just think if we’re in a world moving towards 4k, and now started 8k with the R5, how many options will this camera actually have with little room to play with?

I may be misinterpreting what was written but it makes it sound as though the metric of greatest interest is the size of a cell, while, I would expect, the more useful measure would be effective saturation, in -e, per um.
