These are the full specs of the upcoming new ultracompact, ultrafast and first curved sensor camera! It will feature a 2/3 inch curved sensor and use a damn compact 20mm f/1.2 lens.
The new sensor has the same signal to noise ration of a Canon 5DmarkIII. Quite amazing!

8:3 resolution??
Strange indeed. Non-square pixels.
Why not? I’d assume that the sensor is curved in one dimension only – everything else would presumably be overly costly to manufacture. This curved dimension should obviously be the longer edge, i.e., the horizontal. Consequently, overly high, non-square pixels would be a means of reducing the impact of high inclination angles that still arises in the vertical towards the outer areas. And they may also reflect a difference in actual optical resolution that could be expected from a lens designed for projecting on an aspherical sensor.
Or, to put it the other way round: just consider that a horizontally curved sensor behind a lens of short flange distance is equivalent to a much wider planar projection. Hence, even if the sensor physically is 4:3, its planar projection may well be closer to 8:3.
If they skip every third column when recording in 24p, which is possible with bayer, they get a 5k 16:9 picture.
Similar relations apply for the 30 and 60p. It seems this sensor is designed for video recording.
NO WAY this is a 20mm f/1.2 lens. It is a 7.8mm f/1.2 lens.
If we trust the 6,67mm diagonal and 7,83mm focal length then equivalent focal length would be about 50mm and equivalent aperture (in terms of both DOF and total light gathering) would be about f/7,7.
Nothing makes sense here.
The sensor is said to have a 6.67mm diagonal and be a type 2/3″ sensor. But a 6.67 diagonal corresponds roughly to a type 1/2.7″ sensor (diagonal: 6.72mm) whilst a type 2/3″ sensor has a diagonal of 11mm.
Secondly, a 7.83mm lens in front of a type 2/3″ sensor would deliver the same angle of view as a 31mm lens on a 24×36 camera, not a 20mm one.
And a 7.83mm lens in front of a sensor, the diagonal of which is equal to 6.67mm, would deliver the same angle of view as a 51mm lens on a 24×36 camera, again not a 20mm one.
It’s reassuring to see that the angle is listed in a 35mm equivalence… xDDDD
Sensor appears different than lens, I think these are 2 different rumors. A 7.83 mm f/1.2 lens with a 94 degree field of view is a 1″ sensor. I imagine the curved sensor is for something else entirely? Unless the curved sensor impacts field of view calculation.
The curved sensor has significantimpact on the field of view. As already said, if placed behind (or, should I say, around) a lens of short flange distance, a curved sensor is equivalent to a much wider planar projection. Hence, the usual equivalences between planar sensor formats do no longer apply.
Appears to be a cell phone camera (based on rumor on DPReview Connect), if true it will probably be my next cell phone 🙂
