i have a canon 300d, i have a keen interest in running dogs (greyhounds, whippets, lurchers etc ) i can't seem to get on with the standard lens or my 70 - 300 sigma, the shots i take involve fast panning as the dog runs past me at varying distances (auto focus not suitable) or static shots as the dog runs towards me.....i just can't seem to get it right....so.....what would be an affordable non canon lens (can't afford canon prices i'm afraid) for this type of work ?
ps, some of the shots are in rain as well !
advice appreciated
