The 70-200mm f/2.8 G SSM II Lens from Sony. The standard telephoto zoom for professionals, this full-frame A-mount lens delivers exceptional quality and offers a fast and constant f/2.8 aperture for consistent exposures throughout the range. Further enhancing overall quality is the use of four extra-low dispersion elements to combat aberrations along with a Nano AR coating for limiting flare and increasing the contrast. This version II lens has been improved over its predecessor with enhanced reproduction of fine details across the frame and faster, more responsive focusing. A constant f/2.8 maximum aperture offers consistent performance throughout the zoom range and also lends greater control over focus position for shallow depth of field techniques. A Nano AR Coating has been applied to reduce surface reflections, flare, and ghosting for increased contrast and color rendering in strong lighting conditions. The lens is equipped with a removable and rotating tripod collar for added stability and reducing strain on the camera’s lens mount.
