Its internal zoom mechanism, a first for a 24-70mm f/2.8 lens, provides a robust and balanced build that is also 16% lighter than its predecessor. The constant f/2.8 aperture and upgraded weather-sealing make it a highly reliable and versatile standard zoom for demanding conditions. This lens is best for professional photographers and videographers who require a durable, high-performance workhorse lens for events, portraits, and commercial work.
