The 70-300IS was introduced a bit less than 7 years ago and was much superior to the 75-300IS it replaced (which might be the 10 year old one referenced here). I had a 70-300IS and eventually replaced it with the 70-300L. While the L is a bit sharper wide open at the long end the non-L was no slouch and surprisingly close in performance throughout the range.
