The newer Canon 300/2.8 400/2.8 500/4 and 600/4 have 4 IS modes. Off, normal, panning, and tripod. The tripod mode is designed to reduce vibrations of a different frequency than handholding. That being said, I have the older technology 300/4 IS and I pretty much keep the IS turned on even on the tripod. Warnings of "damage" or blurry images have proved false and I do see an improvement. The only time it is off is for flight shots. -- Christian http://photography.skofteland.net -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
