Image stabilisation

Now the next test - showing how the image stabilisation works. Both the shots below were taken with the Canon 70-200mm L IS USM - at 200mm and 1/30 sec. Ordinarily you'd need a shutter speed of at least 1/250 sec for this length. The un-IS image shows the sort of camera shake one might expect at 1/30 sec, the IS image is also at 1/30 sec but is roughly equivalent to a "normal" shot at 1/250 sec. That's 3 stops.
