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_all_details.asp?id=3324&navigator=6 ) . 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.
