I need a superzoom with a reach of at least 400mm , for shooting motorbikes on circuit.
I've seen some pretty decent pictures taken with the Sigma 150-500mm at 500mm but i'm wondering if a Sigma 100-300mm f/4 with a TC wouldn't give me a better result ?
Look at these
when i see that, i'm trying to tell myself that this is just what i need for exactly the same kind of pictures
