So I was almost sure of buying the nikon d3000, since it's cheap and while it's not the best DSLR out there, it's still a DSLR which is what I'm looking for. But I've been told that it has some issues with the ISO and the shutter closing before than expected or so. I've made some research, and googled for some time now, but can't find anything. I do believe my friend, there's no reason why he'd lie to me, but there's nothing to prove it. Or at least I can't find it. Do you know about this? Is it true?
