During shooting, a high-speed Movie & Stills Compatible (MSC) autofocus system allows you to silently and quickly achieve focus. This focusing system also lets the 25mm lens focus as close as 9.4" for getting tightly framed shots. Additionally, it features a seven-blade circular diaphragm for smooth out-of-focus areas as well as a front filter thread of 46mm.
Included with the lens are the front and rear lens caps, the LH-49B lens hood, and the DR-49 decoration ring. Optional accessories such as a macro conversion lens and case are available.
