The Sony E-mount TTArtisan AF 75mm f/2 Lens is a fast, portable, and autofocus-enabled prime lens ideal for portraiture. Lightweight at 12 oz, the lens's bright f/2 aperture is effective at separating subjects from the background with a pleasing bokeh. The lens can focus on subjects as close as 2.5', while its optical design features an extra-low dispersion element and four high-index elements to increase sharpness and reduce chromatic aberrations. A stepper motor drives the lens's autofocus, resulting in quick, quiet, and accurate focusing that's further bolstered by support for eye, animal, and vehicle detection algorithms. The all-metal lens body features a clickable aperture ring for on-lens adjustment with haptic feedback during use. The lens comes with a lens hood, a front lens cap, and a rear lens cap with a USB-C port for firmware upgrades.
