I just recieved this new lens and finally we had a sunny day. This lens requires a good deal of light to work well, but I knew this already before purchasing it. So far the VR has worked really well. I've taken a few at 1/15 shutter speed with no blur. They VR kinda hums a bit and it takes some getting used to; this is my first VR so that may be the problem. The zoom isn't as powerful as I thought it would be which is a bummer. I might try some extension tubes for extra reach. I use it on a D80 so with the crop factor it's comparable to a 450mm. Luckily the 10.2 mps on the D80 allows for some cropping because most bird pics need a good bit to really see detail. All in all I think it's worth the $570 or so that I paid for it, if only for the VR. Just don't expect to use it indoors without a flash. These were all taken handheld. 1. 2. 3. 4. 5. 6.
