So i had the 70-200 F4L non-IS when i picked up the 70-300 IS USM for a good price. After doing some quick comparision, i decided that the 70-300 is sufficient for me and sold the 70-200 to fund some other L lenses. Now i have been getting interested in the 70-200 F4L "IS". Found a good deal on a six month old mint lens for 800. Just wondering if it makes sense to own it alongwith the 70-300 IS (non-L) ... Any thoughts?
