More fool me! I decided to leave the 70-300mm SSM behind and take this on a trip to a wildlife park some 80 miles away (Kirkcudbright, Galloway). The park is not worth the journey, though it is well kept and will one day justify a visit, there's just not enough there and the caging prevents most photography. We were the only people there apart from one other couple, on a Saturday of a bank holiday weekend, in the afternoon - don't know how it survives.
But the lens proved to be staggeringly good. My cheque goes off to keep this sample. At full aperture it beats the 70-300mm full frame near equivalent Tamron, across the range. I would rate it as one of the best tele zooms I have ever used, and its close up performance as unexpectedly clean.

Quite a severe crop from the original, you can have a closer look at http://www.pbase.com/davidkilpatrick/image/102191096
I will put a review of this lens up soon, I now need to take more shots - I have a few good ones from the wildlife park, including near-macro stuff of fungi, but I liked this one because of the very cute miniature the chick makes of the adult.
