I wouldn't be happy with most of the shots I see on the 150-600 threads but I realize there are a lot of variables at work.
For the most part, I wasn't impressed with the sample photo images out of Sigma 150-600 prior to my decision to purchase it, but when I saw some really good ones, I basically knew that the bad sample photos were due primarily to user inexperience or errors. Of all the sample photos I've seen, the lens that seems to yield the best and consistent results is when it's paired with full frame camera bodies, most noteworthy being Canon 5D IV followed by 5D III. The ones with cropped bodies seem to vary more. It'd be very interesting what the results are going to be like when it's paired with 7D III when and if it ever comes out.
It's also how and when the lens is being employed that could easily cause variances in results. I noticed that I get a lot more keepers when I employ my monopod as opposed to hand-held. There are, of course, factors involving the camera settings, too, i.e., SS, AF, Focus, etc.
I heard great things about 100-400 II, and that's why I inquired to the OP whether it's the original or the II edition... I can see the trading from 150-600 to 100-400 II, but not to the original 100-400.
