(worked in jessops for 6 months)
stick to sony and canon, i've seen a few samsungs go wrong.
sony have a really good lense on them but have rip off things sometimes but canon are generally a good company.
check both there websites usually giving a free batery and bag away if you buy from Jessops (you have to claim it later on, you wont recieve it then and there tho) lol
