Hello everyone.
If possible, i could use a bit of your knowledge if anyone has any info on this. What i would like to know is whether IS will shorten the lifespan of a lens? The reason why i am asking is, here at my department we are looking on our options regarding lenses for some C100's we are buying for our students. So this lenses will be used only for video and after a few quick tests we did here in the office we noticed that the moment the camera is powered, if the IS is enabled on the lens it gets activated immediately and not just when you record. I repeat, this are for students so we are taking any precautions necessary to expand the lifespan of our equipment as they do usually get abused (in the wrong way). So, we do expect that students will enable IS on the lenses and then not switch them off EVER when shooting which means the system will be working overtime. So, coming back to my question, we are looking to see if the lenses with IS will actually be able to take any sort of abuse for the long run ! Trying to find any info around the net has been fruitless so far !
Many many thanks in advance fellow Canonians !!!

That is what we are also thinking here at the office, thought we are,as you say, trying to figure out how this will actually be relevant to real life use !? We are considering our options before the purchase and also thinking if there would be a way of delaying the unavoidable if that is the case. Thus, if we there was the possibility of the IS limiting the lifespan of the lens drastically maybe we should start looking into what we could do further to avoid that (eg. provide more training to the students maybe). But, that will only follow once all the information regarding this matter has been gathered.
