There's a rule of thumb that says at focal length x mm, the slowest shutter speed you can use is 1/x seconds before the image starts to blur. Yet this image looks ok. I think at low shutter speeds, the camera makes use of its high speed by taking several pictures and combining them, instead of one long exposure. I think this was taken in Premium Auto mode.
One of the features of the ZR200 is Multi Frame SR Zoom, which is like an advanced digital zoom. There's a difference between digital zoom on camera and on computer - on camera, the interpolation can be done before the image is compressed, so the image is potentially better. If you don't take pictures at full resolution, you can use digital zoom without losing quality. The camera increases the limits of SR zoom at lower resolutions.
24 mm focal length
Updated 8 July 2012Ok! I finally got around to taking some pictures to test the zoom.
Still figuring out how to test the stabilisation effect of combining pictures.
