Nikon 70-300mm f/4.5-5.6G ED-IF AF-S VR Zoom

FOCUSING/LENS ATTRIBUTES:

Focusing can be quite fast... at times. You'll find, at the Max 300mm focal range, that the lens has a pretty hard time auto-focusing in on a subject. At times it would focus pretty quick, at the 300mm range, while at others it cannot focus at all. You can get around this quirk by bringing the subject into near focus (manually) then letting the auto-focus take over; it works every time. I find this focus problem disappointing especially given the price of this lens.

The quality of the Bokeh (Out of focus areas of the photograph) is very nice and pleasing. The images are sharp, vignetting (dark areas in the corner of your photos) is hard to find and lens flare rarely a problem.

VIBRATION STABILIZATION:

All I can say is that it works... it can come in handy. It's not going to stop the image guaranteed for you; it's only meant to slow down the rate at which the camera moves (vibration from holding). You can notice the difference; with it off you'll see that the image (at say 300mm) really bouncing around; then you flick on VR. It takes a sec or two but then the image smooths out, it still wobbles around, but much more slowly.

With VR enabled, you can usually go 2-3 (sometimes 4) stops down, then what you'd normally be able to do when hand holding.
