It is also the equivalent of a 35-millimeter wide-angle lens, providing an impressive 83-degree field of view, which means solid low-light performance and a very quiet auto-focus operation. For more experienced photographers, this Sony wide-angle lens also offers manual focus so you can fine-tune the shot to your exact specifications. The lens comes with a specialized circular aperture, which offers a smoother and more natural look.
