I also had the version 1, and was hard-pressed to use it at f2.8 without lots of boost in sharpness/contast for inside sports. The world changed for me last year, when I sold my original when the frenzy was on (for 80.00 more than I paid for it), and picked the new one up as part of the Canon 7D/Lens double rebates going on. You will be satisfied!
