content: I had the 70-200 L F/4 usm without the IS, I returned that lens. Without IS it was not worth keeping for me, to many blurry pictures(must be on a tripod) So I exchanged it for this 70-300 IS USM about the same price too. Love it!! Made it all worth while. It's pretty good at up close, not a macro lens. Great with 300mm, Clear and sharp at all ranges. nice walk around lens for me. Very Happy with this purchase.
