>>2890563It's impossible to tell all the problems a lens might have without it being in your hand. Pictures are not good enough. The only reason we buy used over the internet with pictures alone is because we can trust a dealer who has a lot at stake, like a good reputation. Even then, we have great return policies like at Ebay. You can't trust a no name from a barely used service like Amazon's user sales. They could omit anything, or they could be incompetent and not even know. The motor could fuck off within a week, or a bit of fungus was growing in a place that couldn't be seen until it grew too much. Or the lens is all scratched to hell, worth nothing, and the seller just got a free 400 eurobuckaroos.
