Pick Model A if you need a fast f/2.8 aperture for low-light shooting or shallow depth-of-field at wide angles (17-35mm). Choose Model B if budget and extreme telephoto reach (up to 300mm) are priorities, despite its slower aperture and heavier weight. Model A stays the better choice for wide-angle versatility and optical speed, while Model B suits casual shooters needing a single, budget-friendly all-in-one zoom.
