The tests of my new lens continue at the zoo. So far I'm very impressed with the sharpness or it. Most of these were taken at 250mm and above and some even maxed at 300mm. If I had to do it over again I would still buy this lens. I had problems before with the auto focus but my camera settings were causing that. Today it worked perfectly for the most part and I don't even notice the VR at all. I would reccomend a shoulder harness rather than the normal camera strap because it gets heavy lugging it around the zoo for a few hours. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.
