i dun think its seal, but it will be new definitely...
what u get inside, a camera body with cap, kits lens, instruction manual, strap, CD i think can't remember since i dun use it, dunno got cables or not can since i dun use it as well... there will be no battery or charger since this takes AA and its not included....
ask the shop can test or not, ask for batt to test, check the lcd display, go through some of the menus, but dun set the time or anything... mount the lens, check the focusing, focus near, focus far, ask if can take 1 shot, if cannot then say i sure buy 1, of course u better be a serious buyer... take 1 shot see happy or not... check if any physical defects on the cam body... if u are the super kiasu, bring a laptop and load the image to check... but i think this is more for checking lens...
hey can you share alittle bit on the bringing latop and checking lens? what about it?
