Looks like it is doing a good job.

Due to some personal issues and the weather I was unable to get my new lens out in the field yesterday. May not be able to for a couple of days. So, decided to pay at my bird feeders.
So far I have noticed that this lens seams to focus fast. I am very pleased with that! Also, it is not as heavy as I expected. It weighs 4.3 pounds. That is 3.7 pounds lighter than my Sigma 500mm and .9 pounds heavier than my Canon 100-400mm lenses. Not bad at all! Another thing I like is the front optic lens does not rotate. That is a big advantage to anyone that uses filters.
Also, I can focus on a BIF, at say 200 to 300mm, and grab the front of the lens by the hood and it will slide right out to 600mm very easily. That is nice, something I have always liked on my 100-400mm lens. One big difference though, you do need to turn the ring to back off from 600mm, it doesn't slide very easily in that direction.
Here are a couple of quick shots taken this morning. Taken using my 7D, first at 1/500, second at 1/800, both at f9.0
