Good morning again, Jay;
Another 200mm lens to consider is the 3.5/200 AF Vivitar Series 1 200mm 1:3.5 VMC AUTO FOCUS TELEPHOTO lens. These do come up occasionally, and the built-in-the-lens Auto Focusing feature of this Vivitar lens can come in handy in quickly changing situations where you are trying to follow the movements of a bird. In my experience with mine, it is not really any slower than my own movements with manually focusing a lens, when the subject has reasonable contrast and illumination. So far I have been happy with the results on the negatives from my samples. No, it is not quite the equal of the Minolta 2.8/200, but the Vivitar can be found more frequently, it is much cheaper, it is lighter, you are giving up only one-half f-stop at f/3.5, and it really does convert one of my Minolta X-700 bodies set in "P" mode into a true "Point and Shoot" camera.
Enjoy; Ralph, Latte Land, Washington
