IS Lenses Topher
Hey all,

Long-time lurker, first time poster...

I have a quick question about the Canon IS lens series... I just got the Canon EF-S 18-55mm f/3.5-5.6 IS, and I saw that it has a switch where you can turn off the IS functionality.

My question is this: For what reason would someone want to turn off the IS function?

"When you are shooting with a tripod and remote release (landscapes for example), you should turn off the lens VR and IS settings to acheive sharper images. Otherwise, when your camera goes looking for a vibration and doesn't find one, it will continue to look for one, which can cause a slighly shaky result."

1. If you haven't noticed, IS causes a very slight delay.

2. If it's not needed: on a tripod, or if you're shooting at 1/500th of a second, etc. It's best to turn it off.

3. It uses battery power.
