Pick Model A if you need a longer telephoto reach for subjects like sports or wildlife and can work with its f/2.8 aperture. Choose Model B if a bright f/1.4 ultra-wide angle for low-light or creative depth-of-field is more critical to your work, despite the higher price. Neither lens replaces the other’s focal length, so the decision hinges solely on your framing needs.
