These sort of threads concern me, but first.. let me say to OP, sorry to read about the lens issue, thats not good.. now onto the reason im adding to this thread...
Like all modern smartphone cameras, the M8 has a wide-angle lens and at very best, a 2x zoom should be all you should ever zoom in at. Why on earth would someone want to zoom into their pictuires when theyve taken it with a wide angle lens, as any photographer worth their salt will tell you... why not walk upto your subject.. frame it correctly in the viewfinder then photograph it, why on earth would you take a picture of a subject 100 or 200 yards away then zoom in?. A true photographer Does not crop.. we frame our shots and use the full lens space.
2nd, videos on youtube.. why do reviewers take picture in the dark.. then say the camera is rubbish in low light... Turn the bloody light on or use your flash.. what the hell is wrong with people these days.
2 of the greatest cameras in existence, the Rolleiflex and Hasselblad both had flixed aperture lenses.. yet photographers walked upto their subjects framed them correctly or used a mounted flash.
As a photographer these kind of threads make me wince, In fact I think all videos about modern smartphone cameras should be banned, because it would seem that no body has a bloody clue how to take a photograph these days.
If you like to zoom.. get yourself a little Nikon or Samsung compact camera with an Optical zoom and dont spend less than $200/ £200.
Good luck
