I need a better long lens than the 55-250 and I'd really love the new Tamron 150-600 but thats not going to happen for a few reasons mostly budget and the way I would have to make my purchase. I can make it happen in about a year but I really don't want to have to wait that long. So I have decided to go for either the Sigma 200-500 or the Tamron 200-500. I have seen some great photos from both. I have studied both of these lenses and just plain can't make up my mind. If you were going to purchase one or the other, or already have, which would it be, or why did you choose one over the other.
