It won't save poor technique or much beyond still work. I love the ability of it on a tele... like the 70-200 but honestly it is off 95% of the time on mine.
Again... For video IS is a massive +
Remember that the general rule for getting sharp images is focal length/shutter speed = <1
And that for video you are stuck at a shutter sped of 1/50th second if you want natural looking motion at 24/25 frames per second.
For the 135 that means you're very unlikely to get usable hand-held footage (unless you only need a very brief cutaway).
With a 4-stop IS system, you would be able to shoot reasonable hand-held video with a 135mm lens. Consequently for video shooters this would be a killer feature. It has nothing to do with poor technique (unless you count not having every shot locked off on a tripod/dolly/crane as poor technique I guess - but this is hardly feasible for low-budget event/documentary jobs). Much the same can be said about shooting handheld at 70mm - you might get away with it as it's closer to a 1:1 focal length to shutter speed ration - but IS will give you a steadier shot on a more consistent basis.
IS may not be what you look for or need for your own particular usage, however for others (particularly those focussed on video, or who make significant usage of video) IS is a massive advantage in a lens.
Yes, but we are talking about DSLRs where video is a niche. As a commercial/professional photographer I do take video but my bread and butter is from still work. I've always felt that video is a nice addition but not really the main concern for my body selection. I buy a video unit for video and a DSLR for still, so insisting that every lens has IS because it video friendly is like insisting all Ferraris must have a trailer hitch. You know, for that 5% of Italian sports car camping fanatics that travel with a camper.
Canon makes cinema lenses... buy one if that is your interest, leave the cost and weight out of the design of most DSLR lenses.
