I would post more but, I'm running low on space in my photobucket and I'm not so sure how much I can put into my flickr before it wants me to upgrade too.
Thought about that, price is stellar, but optics is always one of those "you get what you pay for" things in my mind. Good find though, and I will be reading more reviews on the Sigma.
I still have my 55-250 for longer shots but used the new one today in rocky mountain national park a lil, crappy weather so only got about a dozen shots but so far its seems to have a really nice range.
