My understanding is that the IS works in two directions at 90 degrees . . . usually perpendicular and parallel to the horizon. In normal "landscape mode" panning, mode 2 would be engaged. The lens would stabilize in the direction perpendicular to the direction of panning with no effect in the other direction. It seems obvious that IS can not possibly be effective in the direction of panning. Trouble is, in my application, I am always panning at an oblique angle. I don't see how IS can be of help here. And my personal experience has borne this out. Perhaps a simple panning operation, with a well behaved object, like a sports car, mode 2 might be effective. I have not had such cooperative subjects
> From: Gerry Morgan <[EMAIL PROTECTED]> ============================== It seems I may have stirred up a bee's nest here !!! I think we need to understand that "IS" is NOT the do-all and end-all invention for photographers, Yes it can work very well (I personally leave IS switched on 100 percent of the time on my 28-135mm (Except when the camera is tripod mounted and MLU is in use !) And about 85 percent of the time on my 100-400mm lens (Mainly mode 1, But will now try leaving it on mode 2 and see what the result are), And then again on some shots it doesn't work very well, I think if it worked 100 percent of the time then nikon, minolta, and pentax users would be very thin on the ground :-) !!! * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
