Pick Model A if you need the lightest, most budget-friendly tele-zoom and can accept a 75–300 mm range with a slightly brighter f/4 maximum aperture at the wide end. Model B stays the better choice if you require the extra reach to 400 mm and are willing to pay the higher price and carry the additional weight.
