Verdict
Pick Model A if you need a wider 20 mm start and a lower price, or if you shoot mostly in bright light and won’t miss the extra reach. Model B stays the better choice if you want the 135 mm telephoto end, built-in stabilization, and don’t mind the higher cost and slightly dimmer maximum aperture at the long end.
