Pick Model A if you need the extra reach to 200 mm and can accept the slightly heavier weight and dimmer aperture at the long end. Model B stays the better choice if you prioritize a constant f/2.8 aperture across the entire zoom range and prefer a lighter lens for everyday shooting between 28 and 75 mm.
