Verdict
Pick Model A if you need a longer reach at a budget-friendly price and can tolerate a slightly dimmer aperture. Model B stays the better choice if you prioritize a constant f/2.8 aperture for low-light performance and sharper results at the wide-to-mid zoom range, despite its higher cost and shorter telephoto end.
