"You can use the zoom function on any SJCAM, but remember it is digital zoom so you will loose image quality. Gopro narrow or wide is also a zoom function."
"I have a SJ4000 and SJ5000+, in terms of better quality pictures and Video then SJ5000+ is the winner, only downside for SJ5000+ dimensions is a little bigger (+-1mm) compared to SJ4000. So my SJ5000+ does not fit on my T2D gimbal."
