The Samyang 24mm f/1.4 ED AS UMC Wide-Angle Lens for Sony Alpha gives you a wide 84deg. view when used with a full-frame 35mm camera, 57.6deg. when used with an APS-C camera or 47.6deg. with Four-Thirds cameras. Four low-dispersion (ED) glass elements and two aspheric elements produce sharply defined images with a minimum of aberrations.
The lens focuses as close as 9.84" from the lens, giving you outstanding wide-angle close-up views. A multi-layered and anti-reflection UMC coating provides superb light transmission and reduced flaring. This lens will operate in Aperture Priority, Shutter Priority, Program and Manual exposure modes. It is a manual focus lens.
