So I have an Olympus E-410 and a 70-300 mm f/5.6 lens. I love shooting sports and really want to get into it more. I can get descent results with what I have now but I want to take the next step up. So my question is, should i stick with Olympus and buy a nicer lens now then upgrade my body later, or switch over to nikon and canon? I know I can get better results right now if I just buy a new lens and keep my body. But I am thinking more long run. I might seriously get into shooting sports, I am trying to get some small jobs for the school news paper and such. So what do you guys think. Also what would be better for shooting sports, Nikon or Canon? Thanks for the help guys.
