As some of you know I recently had an opportunity but opted out of buying the Canon 500L. None the less, I would still like a little more range than my 100-400L offers. After some research, I ran across the Sigma 150-500 f 5-6.3 and it seems like a a good option if the 500L is out of your price range. Based on the FM reviews and the pics on Pixel Peeper, this lens looks like it might be worth the investment, but before dropping that kind of money, I was curious if any of you had experience with this lens---Your thouths are appreciated.
