Venus Optics Laowa 15mm f/4.5R Zero-D Shift Overview

Pairing an exceptionally wide field of view with the ability to correct for perspective distortion, the Pentax K-mount Laowa 15mm f/4.5R Zero-D Shift from Venus Optics is an ideal lens for architecture and interior applications. The broad 110 angle of view is complemented by an impressive +/- 11mm shift range to compensate for unwanted converging lines and keystone distortion. This shift control is further complemented by a 360 rotation mechanism applying the movements in various directions to suit both horizontal and vertical orientation shooting. Additionally, as part of the Zero-D lens series, this 15mm f/4.5 also renders scenes with a high degree of accuracy and very low distortion.

In terms of optics, two aspherical elements and three extra-low dispersion elements are featured, which reduce both spherical and chromatic aberrations for high sharpness and clarity. An anti-reflective coating also helps to control flare and ghosting for heightened contrast and color rendering. The lens uses a manual focus design for working with subjects as close a 7.9″ away and has a fourteen-blade diaphragm for producing subtle 14-point sun stars.

Ultra-wide lens is designed for Pentax K-mount mirrorless cameras. As part of the Zero-D series, this lens has a rectilinear design that renders subjects with minimal distortion in order to suit architectural, interior, and landscape applications. Integrated +/- 11mm of shift adjustment helps to correct perspective distortion and eliminate keystone distortion. Large 65mm-diameter image circle easily covers full-frame sensors without any vignetting. The shift control works in conjunction with 360 of rotation for applying the shift in various directions, benefitting switching between vertical and horizontal shooting orientations, and the rotation mechanism has click stops at 15 increments for intuitive handling. Two aspherical elements limit spherical aberrations and distortion for improved sharpness and accurate rendering. Three extra-low dispersion elements reduce chromatic aberrations and color fringing for increased clarity and color neutrality. Updated anti-reflective coating suppresses flare and ghosting for improved contrast and color accuracy when working in strong lighting conditions. Manual focusing design and a minimum focusing distance of 7.9″ suits working with close-up subjects. Fourteen-blade diaphragm produces subtle 14-point sun stars and specular highlights when stopped-down and photographing point light sources. Compatible with optional Shift Lens Support for more balanced mounting and to better enable using the lens for shift-type stitched panorama shooting without parallax error.
