Pick Model A if you need a fast, ultra-wide prime for low-light or environmental shots and want to save over 400 EUR. Choose Model B if your priority is a long telephoto reach with a bright f/2.8 aperture for distant subjects, regardless of weight or cost. Neither replaces the other; the decision hinges solely on focal-length needs.
