Ok, seeing as how this is a fairly large investment I am putting much thought into my purchase. I have come into decent deals on both the 80-200 AF (push-pull) and the 80-200 AF-D (2-ring). The pusher is selling for $400 and the 2-ring is $700. I work for a newspaper (not sports) and also shoot weddings and portraits, so I don't think the slow focus speed will ever give me issues on the push pull BUT it might and I don't like that. Plus the old pusher doesn't have a tripod collar. However, it is $300 dollars cheaper and in better shape (minus broken aperture lock). Now I'm fairly inventive so I'm sure I could fabricate something that would secure the lens to the tripod without extra strain on the camera mount. I guess the end question is what do you guys think push pull for less or bite the bullet and spend more on the 2-ring.
