Canon EF 70-200/4,0 L IS USM vs 70-200/4,0 "none IS" Just for fun I'm looking at telezoom lenses online. Now I just came across the Canon 70-200 and noticed that there is one with IS and one without. Is that the only difference between them? I noticed comparing the price it's almost as twice as expensive with the IS one. If the IS is the only difference between them, is it really worth almost twice amount of money for the IS version?
