Nice picture.

It may be that you could get a crisper image by stopping down to f/7.1. At the long end, this lens goes a bit soft when wide open. I have done some tests that show it improves at f/6.7 and is best at f/7.1. f/8 is good also but not an improvement so I think f/7.1 is best to use.

Good info Tony.  I did some testing of my own comparing it against a few lenses and whilst I only tested it at 1 stop intervals, i found that wide open it aint the best at 300mm.  I am thinking that the Oly 75-300mm (at least the original version) may be a tad better but that is just based on one link (that i have lost of course lol) wher a guy compared them both and the Oly wide open at 300 certainly had better contrast and appearance of detail.
