I'm pretty sure many questions have been asked before about this lens but anyway here goes.
I've been using the 70-300 Nikon lens on my D5000 for about a year and really want to move up to something longer, within my budget.
What I would like to know is how would this lens compare to the speed of focusing of the 70-300, is it soft at 500mm and how does it cope on overcast days. Especially fast moving motorsport.
I do a lot of motorsport photography and love panning usually between 200-300mm.
So in summery having been very pleased with my 70-300mm lens will I be disappointed with the Sigma.
Thanks
Del
