Just thought I'd let you guys know I'm taking the E-520 and 70-300mm out to shoot a national mountain bike race at the Deer Valley ski resort, today. I'll actually be shooting up there all weekend. And I'm gonna give the E-520 a full sports workout. I'll add some photos to this thread later. I'm looking forward to using the 70-300mm for a mountain bike race. I think it's gonna be sweet!
