Pick Model A if you need a fast f/1.4 aperture for low-light performance or shallow depth of field, or if the 24mm focal length better suits your shooting style. Choose Model B if you prioritize an ultra-wide 15mm perspective and can work with the slower f/4.5 aperture, or if size and weight are critical factors.
