1 - Optical zoom gives a better image than the recalculated image in the digital zoom - Samsung depth of field 1.8-3.9, JVC gives only one 1.8 unless you understand the example: cut a hole "1" with a diameter of 20mm and "2" 7mm into the paper. Now look at a distant multidimensional object such as a house on the street with one hole and the other hole, you will see that the smaller "2" has a sharper image in a larger range than the hole "1", where you can only sharply see the house but not the street. You can also change the image quality with variable brightness 3 - JVC is heavier, which means it sits more stably in your hand - if you have a light object in your crouched hand longer, it will shake Comfort of operation set the correct basic parameters before shooting and then use only those working controls - start-pause-stop Zoom or if there is (manual) focus and aperture (brightness) I will not determine which, you have to decide for yourself. The technique of the camera is not so important, but the person who uses it, his view of the shot and the idea of a good cameraman will also use the Camera obscura.
