A constant f/2.8 aperture across the 16-55mm zoom range pairs with four aspherical and three ED elements for sharp, high-contrast images on APS-C bodies. Its 494g weather-sealed build and fast XD Linear Motor autofocus make it a portable, durable workhorse that handles quickly in changing conditions. This lens is best for travel and landscape photographers who need a single, bright zoom covering 24-82.5mm equivalent without the bulk of full-frame glass.
