Pick Model A if you need a brighter f/1.4 aperture for low-light shooting or shallower depth of field at a wider 28mm focal length. Choose Model B if you prefer a more compressed 65mm perspective and lighter weight, accepting the one-stop slower f/2 aperture for the same budget. Model A stays the better choice if versatility in tight spaces or astrophotography is a priority, while Model B remains ideal if portrait or mid-telephoto work suits your needs.
