I kinda like my dump truck. It's rugged and useful and gets the job done

But Daniel is right about the comparison. I actually sold the 70-200 L f/4 IS to get the 70-300. The only reason was to gain 100mm. That particular 70-200 is an incredible lens, especially considering the size, weight and cost.
