Pick Model A if you need a versatile everyday zoom that covers wide to short-telephoto ranges and can handle low light slightly better at the wide end. Choose Model B if your priority is ultra-wide-angle framing, portability, or shooting in tight spaces, as its 10–18 mm range and lighter weight suit those needs at the same price. Model A stays the better choice if you require reach beyond 18 mm or prefer a brighter maximum aperture at the wide setting.
