Pick Model A if you need a single, all-in-one travel lens that covers wide-angle to super-telephoto (18–250 mm) and don’t mind the smaller maximum aperture at the long end. Choose Model B if you prioritize ultra-wide (10–24 mm) perspectives for landscapes or architecture and prefer a slightly faster aperture at the tele end for the same 95 EUR.
