With an ultra-wide focal length of 16mm, the new lens is ideal for various different types of photography, including selfie shots of multiple subjects and photos in confined indoor areas. In addition, with a minimum focusing distance of 0.13 m maximum magnification ratio1 of 0.26, subjects appear large while background are emphasizes, providing an enjoyable means of expressing perspective.

Taking advantage of the characteristics of the RF mount, a large internal mount diameter and a short back focus2, enables placement of an optical configuration comprising 9 lens elements in 7 groups close to the imaging plane on the camera side, making possible high image quality in a compact and lightweight design. What’s more, it features a fast f/2.8 aperture that supports indoor and nighttime shooting, as well as a fast shutter speed that helps capture moving subjects. The lens design is compact and lightweight, measuring approximately 69.2 mm long and 40.2 mm wide and weighing approximately 165 g, making it easy to carry.

1 Magnification refers to the ratio between the size of the subject and its size when reproduced on a camera’s image sensor. A magnification ratio of 1.0x (1:1) means that a subject can be reproduced at its actual size on the camera’s image sensor
2 A short distance between the optical axis from the vertex of the rear lens element to the imaging plane when focused to infinity.
