A bright prime with a versatile focal length, the 27mm f/2.8 AF Lens from 7artisans Photoelectric sports a lightweight metal build and is designed for Sony E-mount camera systems. Providing a 40.5mm full frame equivalency and a 1' minimum focusing distance, users can capture detailed close-ups and flattering portraits which include much of the subject's background. The lens's STM stepping AF motor and eye recognition focusing support helps ensure image sharpness for both stills and video.
