Of course, sigma is bound to the same laws of physics as everybody else, and creating. The lens is far lighter and smaller than most lenses with a constant f/2.8 aperture. A wide angle lens is one with a focal length of less than 35mm but more than 16mm.
The Lens Is Far Lighter And Smaller Than Most Lenses With A Constant F/2.8 Aperture.
