The current size for pictures taken from the Xperia X camera is either 16 Mpixels in 16:9 aspect ratio, or 13 Mpixels in 4:3. These resolutions are too high for most cases (as a comparison, the Nokia 808 allows 5 or 8 Mpixels). It would be good to add a set of further resolutions down to at least 4 Mpixels, of course obtained by resampling (reducing noise) and not cropping the pictures, and (as asked in another question) including 3:2 aspect ratio to match photo paper size. Resolution selection should be possible on the fly from within the camera interface, rather than from the app settings.

I concur in general, but it would be even better if it were possible to have a "lossless" zoom mode (that is, use the central part of the sensor only up to the non-interpolated resolution). This way, you could have a (relatively) good zoomed 2x-3x image at 8MP, or even more at 5MP.

@mikelima If the images are scaled down, the lossless zoom comes for free until you reach a used part of the sensor that has the same size as the output image.

To clarify: If you are getting an 8-Mpixel image from a 16-Mpixel, you will on average get one pixel out of two of the original image (therefore reducing noise that is "averaged" out). If you zoom until you use the central 8 Mpixel of the sensor, the output image is the real sensor output. Zooming further, you need to interpolate and each pixel will contain less than one "pixel" information.

(Actually the lossless zoom is lossless with respect to the sensor data, but has a quality loss with respect to the non-zoomed image which can use more than 1 sensor pixel to get 1 image pixel.)
