Verdict
Pick Model A if you need the extra 4 mm at the wide end, image stabilization for handheld shooting, or a lighter setup. Choose Model B if a brighter f/2.8 aperture is critical for low-light performance or shallower depth of field, and the 28 mm starting focal length suffices for your needs.
