I do see your point,but not sure i could'nt have zoomed much( was sat at the back of the vnue,as i paid extra for seats) with the zi8 without really using a lot of battery power.Also the battery i have for my sony cam has about 6 hours of life when fully charged so i was free to zoom as much as i wanted.Also the owner of the venue is sometimes hanging around the soundguy,and wipping out my cam( zi8) in full view wouldnt be smart.Hes a bit of a dick tbh,and didnt want to let him see.I think there were also band people ( promoter etc ) hanging around and really didnt feel comftable at times.Anyway i got it done and im sure for a stealth job,i think it may have come out pretty good.I also recorded seperate audio,so maybe a half decent dvd can be created.Not sure im going to make a habit of stealth filming,but when im feeling brave enough,who knows.
