This lens has 16 elements in 11 groups with 2 aspherical elements and 3 ED elements, bringing impressive control on chromatic aberration and ensuring the image sharpness is consistent from the center to the edge.

 Laowa 20mm f/4 Zero-D Shift is one of the “Zero-D” members, the distortion is nearly zero meaning any straight lines can be maintained from corner to corner. It is a must-have advantage for architectural, commercial, interior, and landscape photographers because the post-editing time is much shortened for the image to look real.

 The 14-blade aperture creates smooth and circular bokeh, the effect is pleasantly astonishing in architecture photography.

 Apart from far-away architecture, Laowa 20mm f/4 Zero-D Shift also supports capturing very close objects with a 25cm minimum focusing distance. Wide-angle macro images can be created easily without changing lenses.

 The 360° rotatable lens hood shades the front of the lens, keeping the images away from unwanted flares and a washed out. It is extremely convenient to use when there is a strong light source from the side. Photographers can also adjust the angle of the lens hood to avoid blocking the image when extreme shifts.

Laowa 20mm f/4 Zero-D Shift is designed with 82mm filter thread. The screw-in filter can be used which is cheaper, lighter, and more compact compared to obtaining a separate filter holder.

The new lens support is compatible for both 20mm f/4 Zero-D Shift and 15mm f/4.5 Zero-D Shift. The rotatable ring outside is specifically helpful to retain the axis of the image when changing orientations and shifting. It is especially important to achieve perfect stitching for panorama photography, the shift lens support makes it much easier.
