  I've not used the A710, so my comments may not be applicable to that camera. However, if the IS in it is similar to the Canon S3IS which I have used before, it should be quite effective.
  
  Basically, IS in the S3IS would be able to gain you a two stop advantage in shutter speeds. This means that if your best handholding technique occurs at 1/30s shutter speed, with no handshake noticeable at a fixed focal length (or in layman's terms "your zoom level"), IS will be able to take you one stop lower to 1/15s, and another stop to 1/8s. So your handholding technique "improves" with the help of IS.

  The effectiveness of IS is measured by the number of stops it can help you, and if I'm right, IS in the A710 should give you a two stop advantage. In DSLRs, IS may even grant you three to four stops. The Nikon term for IS is VR, Sony/Minolta's AS, Panasonic's OIS etc.

  Hi.... i know S3 IS is good..... one of the first IS enable Camera of my choices. But it does not come with underwater casing.... Canon doesn't make them. A 3rd party casing cost around 1K....... a normal make for Canon casing cost $369 but could be found for about $280.
  
  So, pricing is also very important...... but thxs for the info.
