Pick Model A if you need a versatile, lightweight zoom for everyday shooting and portraits at a budget-friendly price. Choose Model B if your priority is extreme telephoto reach for wildlife or sports, and you can accept the slower aperture and higher cost. Model A stays the better choice if low-light performance or compact size matters more than long-range magnification.
