Samsung S23 Ultra Moon Photos

The photos shown below were taken with a Samsung Galaxy S23 Ultra smartphone using the default camera configuration using Samsung's Scene Optimizer technology to produce sharper images. Click each image to view an enlargement.


This smartphone automatically uses the 10x periscope lens/sensor for zoom levels of 10+. The f/4.9 lens has feq=230mm with a sensor size 1/3.52". This corresponds to an actual sensor (diagonal) width of ~ 4.5mm and therefore a real focal length (correcting from the equivalent 35mm spec) freal ~ 24mm. The actual lens diameter is D ~ 4.9mm.
The angular resolution limit for this size lens as given by the Dawes' limit of optical diffraction is:
     Res = 116/D(mm) ~ 24 ∠sec (or 0.00012 rad).
The moon angular diameter is ~ 0.5 ° or 1800 ∠sec. Therefore the camera lens under ideal conditions (tripod and clear view of moon and image stabilized) can resolve details on the scale of ~ 1/75 the moon diameter. This is consistent with the level of detail visible in the images taken using the periscope lens at ~ 30x zoom. The smallest diffraction limited detail of 24 ∠sec corresponds to a sensor dimension of:
     x ~ freal*Res ~ 0.003 mm = 3µm
or about 3 times the 1.1µm pixel size of the periscope sensor which is clearly able to resolve image details down to the diffraction limit of this smartphone lens.
