ive got a stealth cam with a flash, when i first set it up i had it take 3 pictures at a time, all the pictures i had where the deer running away with flags up by the third frame. After about 2 months that all changed they got used to camera and knew it wasnt going to hurt them. Now i get great pics and it doesnt seem to bother them at all. If you have a good place for your camera i would suggest to leave it in the same spot for a period of time and let them get used to it, maybe even put out a salt block (if you are in an area where baiting is illegal get the salt block out of there 10 days prior to hunting season) with thatbeing said the camera you have will work fine there is no need to go spend a bunch of money on a new cam. in fact if your going to spend over $300 on a camera you can buy 6 stealth cams for that. you have to go check them more often to reload the film but thats just an excuse to go to the woods.
hope you get some great pics
