Verdict
Pick Model A if you prioritize a lower cost and don’t need the extra 4 mm at the wide end. Model B stays the better choice if the wider 24 mm focal length is essential for your shooting style and you’re willing to pay the higher price. Both deliver the same constant f/2.8 aperture and zoom range from 70 mm.
