I'm considering bailing on my 80-200 AF-D to pick one of these up or just setting aside a few bucks to pick one up. For the price, we should all have one of these! Great pics!
I had two of them. I liked them, especially at F4 where they are sharper than F2.8. The built in shade is handy but I bought a longer screw in 72mm shade which was nice and more effective.
