John, The movement required would be the same for say a 500mm lens independent of sensor size - a point in the middle of the sensor would still move the same distance with the same angular displacement of the camera/lens combination.
Still I am impressed with getting a fair proportion of my shots with a 500mm mirror lens sharp at 1/90th hand held without bracing myself. This is on the K10D. The large movement available in the K10D sensor support plate is evidenced by the clearly heard thunk when you tip the camera from side to side (when the camera is off) Rod ___________________________________________________________ -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of John Forbes MJ quotes Canon claiming that in-body SR is no good for long lenses, because it would require the sensor to move by 1/4 of an inch. They are talking of course about full frame 35mm. The required movement would presumably be rather less on an APS-C sensor.
