Well I only recently acquired my first VR lens, an 18-105mm f4-5.6 DX. I am far from convinced of the magic of VR. I haven't bothered (or had time) to do any tests with it yet, such is my enthusiasm for the feature. I did use it for the Queens Jubilee beacons but I was very disappointed by the result's, the nearest beacon was about 5 miles away but despite holding the camera against a concrete signpost and taking perhaps ten exposures, not one was really sharp. Wen I got home I discovered the VR wasn't turned on... Silly old fool! I will post the results, hopefully this weekend? Can all have a good laugh... I don't find the combination of the D3100 and my 18-105 lens particularly pleasing from a sharpness point of view even in good light. I am tending to use the D3100 with the 18-105 for snapshots in a casual way with little or no thought for technique. I usually use a much higher ISO with the D3100, 400, 800 or even 1600 occasionally, mostly to cope with the slower lens and to be able to keep a reasonable shutter speed. My 'work' camera is a D200 usually with a fast, manual focus, non zoom lens attached. The D200 is usually on a tripod or monopod, with an f 2.8 non zoom stopped to between f4 and f8. I rarely use anything other than ISO 200 with the D200. Sharpness (or lack of it) seems to be less of a problem with this combo, despite the manual focus. I am very surprised at the suggestions that sharp images can regularly result with a 200mm lens hand held at 1/60 Sec, even with VR. 1/500 Sec would be my choice, or a (solid) tripod.
