With its 94.5º angle of view and shallow

depth of field enabled by the maximum

aperture of F1.8, this ultra-wide-angle lens

offers vast creative possibilities. The large

aperture of F1.8 aids hand-held shooting

in available light, making it ideal for indoor

use as well as architectural and landscape

photography. For close-up photography, the

minimum focusing distance is 20 cm with

a lens-to-subject working distance of 6.5 cm.

Aspherical lens elements effectively correct

aberration and minimize vignetting, providing

superior peripheral illumination. The rear

focus system eliminates front lens rotation,

making the lens particularly suitable for

attaching the supplied petal-type lens hood.
