Below is a quote I have copied from a review of the new 70-200 f/2.8 IS lens from The Photography Website of Edward Agnew. This, IMO, solidifies Arthur Morris's claim. Ray Amos ******************** IS FUNCTION The IS system functions almost identically to what I have become used to with my 300mm F2.8L IS and 600mm F4L IS lens. All three do not cause the image to do anything strange in the viewfinder or create other disturbing actions, which I have heard, but about with Canon's older IS lens. The only way to tell the IS is up, is that about one second after activation, the image just stops moving with body jitter, and in a quite room, you hear the IS running, sounding like a number of ball bearing rolling around in a can. The owner's manual indicates the lens automatically turns off the IS when the lens is mounted on a tripod, however, When I put it on a tripod, it acts much like my IS super telephotos, that is, the IS does work and does reduce movement. Also, the same as the super telephoto, when I put the IS system in to mode II (horz. panning mode), if the lens did not pan for few seconds, the lens returns to IS mode I by itself. Again this is not in the manual, but then again, it was not in the original manuals with the super telephotos ether. Just goes to prove that you can't always believe what you read. -- All outgoing mail is Virus scanned by Norton 2002 Anti Virus * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
