Yesterday my lens when crazy, would nt work on my rebel, was vibrating, getting error 99 and error 1 messages every shot (all of a sudden) turns out just was just the battery, tho the battery was reading half full still. Just curious if anyone else had this experience?

When my battery gets low and I'm using the IS mine has a tendency to have a mind of it's own too!

I don't get errors, but it has a real hard time focusing, won̢۪t take pictures, etc...

I have not had these problems yet, even with a low battery (knock wood). Then again, I have a different camera. Not sure if that makes a difference or not in this case...

i have heard that IS sucks more energy than a non-IS lens

I was told that IS is a real battery drainer but as far as I can see it only comes on after the shutter has been depressed half way. If I get an error on the 75-300 I'll make sure to turn off IS as a first possible cure (my first 'extra' purchase with the 300d was a spare battery).

doh! edited as I don't know the length of the lens

I have had this happen in low light where the AF was having a difficult time. I would get the err 1 message and have to slighty detach the lense to reset. After that and in good light I had no other problem with the IS, and using the same battery.
