Impressive lens and impressive images as are the ones posted with your 300 f/2.8. I use the older 300 f2.8 IF and am anxious to use it "more" regularly with the AF-S Teleconverter TC-20E II which is fully compatible with this older 300. I've done a few test shots but don't get to take full time possession until 25 Dec! Nice shooting and more for the future.
