Alright so i need your guys help, basically i am looking at getting a new lens for my camera, most likely the canon 70-200 i havent decided on whether f2.8 or f4....but thats for later, basically for you guys that have used IS (Image stabalization) and VR ( vibration reduction) lens, is it really that amazing...ive heard on the web that some guys only buy IS/VR lens, but ive met a couple people that have the non-IS version and the shots are simple amazing....so is IS/VR a scam or what up......any help will be K++++
