And there are tricks to squeeze even more DR, without motion artifacts, like averaging 4 or 6 frames, or exploiting the black sun correction to squeeze more highlights.įor low light, in rolling shutter mode, the smaller sensor is better on paper, despite its smaller size (I expect it to be about 1 stop better). Not bad for a very fast sensor with global shutter. In low light, it's only 0.5 stops behind the 60D in 1080p RAW (1734x975), and about 2 stops behind 5D3 in 1080p RAW ISO 6400. At its base ISO, it's really close to the 5D3 in 1080p RAW at ISO 800 (note that 5D3 ISO 800 in LiveView is more like DxO ISO 500). I didn't test this mode, but with proper 2x2 binning (without introducing additional noise), this sensor would catch up (but that's because Canon does poor downsizing). The row noise (banding) is a major problem, and I don't currently have a solution for it. If my math (and also DxO and sensorgen's math) is not screwed up, this sensor is on par with the little Nikon 1 V2, and about 1 stop behind a Canon 60D. At high ISO, the noise improves by only 0.4 stops. The base ISO is about 400 (maybe lower once you attach the IR blocking filter), and it goes to about ISO 1250 with analog amplification. Global shutter and 300fps are not free - you lose a little low light ability, but not much. Check out some of his detailed calculations here, where he mentions: A1ex from ML has said that depending on how the Super 35mm 4K sensor is sampled, it may be capable of a whopping 800fps in 1080p mode, which would be incredible (though this wouldn't necessarily be something available in the first iteration of the camera as it's limited by its outputs at the moment). This is huge news, as they have done some amazing work with Canon cameras (and will continue to work on them), and they will likely be able to do far more with Axiom as they'll have full access to all of the source code.
Not only that, but the project will be receiving the support of the Magic Lantern team.
