Uniquely fast and versatile, the FE 50-150mm f/2 GM, from Sony, is a normal- to short-telephoto zoom distinguished by its impressively bright f/2 constant maximum aperture. Ideal for portraiture, weddings, events, and indoor and close-range sports, this lens is also a good choice for photographers and videographers looking to replace a handful of primes with a single fast zoom without sacrificing on speed.
