This is a lens that has taken operability and performance to the next level in response to strong demands from users, such as a mechanism for locking the position of the mount tightening ring, a mechanism for locking the EE mark position of the diaphragm ring, reduced weight, black processing of the front ring, and expanded range and active adoption of multilayer coating.

Despite an ultra-wide angle of 20mm, this lens is the brightest in the world at f/2.8, and is a retrofocus type that offers sharp image from short to long distances through the use of a floating mechanism.
