I own a Canon Digital Rebel EOS; before I ditch it for something else what's a good lens to buy for automotive photography? I own the default 18-55mm Canon lens, and a Tamron AF75-300. I find that I like to take most shots around 40mm to 80mm. My biggest issues with the setup is saturation, noise and sharpness all before post processing. By using the CPL the saturation is almost dead nuts perfect. Seams like a lot of the noise comes from me trying to "sharpen" the photo post processing and I always use a tripod at 100iso on a shoot to have the least noise in the photos as possible. If I fix the sharpness/clarity issue it may fix the noise as well. I believe I'm as precautions as I can be to keep these things from happening so it has to be the lens(s) or camera. Any thoughts or suggestions? If you think its a lens issue what would you suggest within reason?
