100-400 IS L series lens in Canon EOS Mount Posted May 29, 1999 I have been using a 300mm L IS for about a year now on and off the tripod. Regarding the IS function on the tripod if you look carefully you will see the image frame "wander" when IS it tries to compensate for non existant movement. Without having got a sensible answer from Canon in Norway I deduce from this that when you go slower than 1/15th this is going to cause problems. I haven4t done any tests though and only use IS on the tripod if I am working fast hands on camera or if thereis a lot of wind. Otherwise I stick to "conventional" methods......Mirror lock with the2 sec timer is my favorite.
