It's really misleading to describe any of the fake focal lengths as "prime lenses". All of the iPhones lenses are technically prime lenses, but the new focal lengths are just digital zoom with some extra post processing.
- astrange 3y agoZooming a 48MP quad-Bayer camera is not exactly digital; you can reconfigure the sensor to be a different resolution.
- dogma1138 3y agoIsn’t sensor reconfiguration still considered digital crop/zoom since it’s not part of the optical element of the camera? When sensors with microlense arrays become more common things will definitely become more complicated tho. We’re probably about 5 years from consumer grade MLA sensors still tho.
- astrange 3y agoIt's not part of the optics (since you can't move the lightwells) but I think it's still part of the analog system, so it's different from working on pixel or Bayer values.
- 4gotunameagain 3y agoIf you reconfigure the sensor without cropping you do not end up with a zoomed image, just with a reduced resolution one. With a fixed focal length in order to zoom you need to decrease the sensor size, therefore cropping, so digital zoom
- astrange 3y agoNot if you default to reduced resolution mode, then you can reconfigure to an increased one ;)
- 4gotunameagain 3y agoaaah interesting. Then the resolution is increased, but how does it affect the overall image quality since you have the same amount of photons in more wells ?
