Does battery consumption depend on your lens?

Question: Does battery consumption depend on your lens!?

Hi Friends, I recently purchased a Canon 70-200 f/2!.8 IS lens ( http://www!.adorama!.com/CA70200ISU!.html )!. Before this, I had a smaller sigma 18-200 lens f/3!.5-6!.3 OS ( http://www!.sigmaphoto!.com/lenses/lenses_!.!.!. ) !. My question is, will my battery drain out much faster now, because the lens is almost 2!.5 times larger in size!. Thanks in advance!.Www@QuestionHome@Com

No, not in the way you mean!. If you set any lens to continuous drive AF, it will have a greater drain on batteries than single servo!. also, IS (VR, or OS) puts a drain on power as well, but both lenses you've listed have those features!. The drain will likely be the same!. Size is irrelevant!.Www@QuestionHome@Com

The only thing that matters on your lens is the "IS!." This drains battery power!. I see you said that the Sigma is an "OS" model, so I'd guess that it's not going to be much different!.Www@QuestionHome@Com

Yes, the IS sure does drain the battery

You should get a battery grip for your camera--it will last twice as long!.

Note: Never mount or dismount the lens with the shutter release button pressed!Www@QuestionHome@Com
