Is image stabilization really important? I'm trying to find a cheapish Canon 75-300mm lens or 55-250mm lens and I can get some good cheap ones but they don't have image stabilization. I can find a select few but they are $100+ more. Is it not that important a feature which is why they are hard to find or is it a needed feature? Taking my pictures now I don't seem to shake but I'm sure it does more than that. I have a Canon SL1 if that matters. I mostly take landscape, wildlife (nothing to exotic) and everyday objects. I also have a tripod when needed.
