Need someone to tell me the camera preview and picture resolutions in Samsung Galaxy S4
According to the Samsung site, the rear camera is 16MP with 10x Optical Zoom and enhanced SMART Modes, OIS, 24 - 240mm, F3.1 - F6.3.

You can probably use this tool to calculate for a rough estimate of image dimensions. Probably better if somebody with an S4 Zoom can provide actual values.

4000 x 4000 (16,00) - aspect 1:1 (1,00 - square)
4472 x 3576 (15,99) - aspect 5:4 (1,25 - photo)
4512 x 3544 (15,99) - aspect 14:11 (1,27 - photo)
5096 x 3136 (15,98) - aspect 13:8 (1,63 - photo)
4616 x 3464 (15,99) - aspect 4:3 (1,33 - photo)
4736 x 3384 (16,03) - aspect 7:5 (1,40 - photo)
4896 x 3264 (15,98) - aspect 3:2 (1,50 - photo)
