I didn't say they gave it a spectacular review, just that they reviewed it, and also that I always read the gear reviews there because they are honest and tell you whats good, as well as whats not so good. Hence their review sentence "I would say most of the time, autofocus is fairly good for tracking birds in flight." Pretty straight forward I would say, not sugar coating it at all and telling you whats not so good. Its up to the reader then to make a determination after that. After reading reviews from Pros, it is always a good idea to get feedback from actual owners of a piece of equipment, thats for sure. Your initial response to the OP on this lens was what was posted on DPReview. I gave a website that reviewed the lens, and pointed out things not so good, which is what someone purchasing gear would want to know.
