Pick Model A if you need a versatile telephoto zoom with a fast f/2.8 aperture for low-light or shallow depth-of-field work. Choose Model B if your priority is ultra-wide fisheye coverage for creative distortion or tight spaces, and you can accept the slower f/4 aperture. Model A stays the better choice if reach and speed outweigh the novelty of fisheye effects, while Model B is the only option if you specifically require 8–15mm focal lengths.
