LAOWA 20mm f4 Zero-D Shift Pentax K

LAOWA 20mm f4 Zero-D Shift Pentax K

It offers outstanding optical properties and technical features. The angle of view is an enormous 94.4 degrees, 117 degrees for a complete shift panorama shot. This corresponds to a focal length of approx. 13mm. Thanks to a maximum shift of up to +/- 11mm with full format, this lens is perfect for architectural photography. In medium format, the shift on the X-axis is also up to +/- 11mm and on the Y-axis up to +/- 8mm. Even very tall buildings can be photographed with this lens without any falling lines. Shifting would also be possible today using image processing, but this would crop the image and thus reduce the advantage of the large image angle. It also saves work and preserves the quality of the original. The 20mm f/4 Zero-D Shift is another lens in the successful LAOWA Zero-D series, with which photographers obtain image results with straight lines without distortion. This top optical performance and great sharpness is achieved thanks to 16 elements in 11 groups with 2 spherical and 3 ED elements.

The close focusing distance of just 25 cm allows impressive close-ups, while the focal length of 20mm ensures a very natural perspective in the wide-angle range. The high-quality lens coating has also been improved once again to further minimize flares and ghosting in addition to the already significant reduction in chromatic aberration. Thanks to the 14 aperture blades, a very beautiful 14-ray sun star is created when shooting against the sun or a point light source. The built-in rotation function allows photographers to change the shift direction to portrait format in no time at all. The mechanism is available for a full 360 degrees, with the lens locking into place every 15 degrees.

Another highlight is the rotating lens hood, which can be turned specifically in the direction of the incoming light to avoid unwanted reflections. As the front does not have a dome-shaped glass element, screw-in filters with a diameter of 82 mm can be used.
