It's just a brand to differentiate their lenses. Think Chevy, Buick, Cadillac.
From what I understand, the Art lenses are focused more on fast speeds, image quality, etc. Contemporary are their middle of the road. Sport are focused on weather sealing and rugged construction. Oversimplified, but that's the just of it.
Thank you!!! That explains a lot. I appreciate your time.
