Laowa AF 10mm f/2.8 Zero-D FF

The Laowa AF 10mm f/2.8 Zero-D FF is an ultra-wide prime for full-frame mirrorless cameras. Laowa offers it in Sony E and Nikon Z mounts, so pick the version made for your system. It arrived in 2024.

At 10mm it suits architecture, interiors and any space where you cannot step back. Wide landscapes and night scenes also fit its sweeping view. The Zero-D name points to a design aim of low distortion, useful when walls and horizons fill the frame.

The fixed 10mm view means changing position to adjust framing. That also changes perspective, so check the view when walls or barriers restrict movement.

The Sony E version weighs 14.8 oz (420 g) and measures 2.79 in (70.8 mm) long and 3.23 in (82 mm) across. Allow space for the wide body when packing a bag. The front takes 77mm screw-in filters, useful for neutral-density filters during daylight long exposures. Check that a chosen filter does not enter the picture.

A 10mm view on full frame is useful for interiors, architecture and cramped spaces. How much fits depends on position and the scene. Nearby objects can look large against a distant background. Keep people away from the extreme borders when edge stretching would distract from the composition.

The lens opens to f/2.8, its widest setting. That helps in dim interiors, dark corridors and at dusk, when you want to keep the ISO low. The wide framing and bright opening also pair well for night-sky scenes.

A wide view does not ensure that foreground and background are both sharp. Depth of field depends on aperture and focus distance. A close subject can have a soft background at f/2.8. Stop down when more depth is needed, and inspect details at different distances.

Closest focus is 0.4 ft (12 cm), so you can work very near a foreground detail. A rock, a doorway edge or a floor pattern can then anchor the frame while the wide view keeps the room behind it. Perspective from that distance is strong, so check the frame edges before shooting.

Use cover in persistent rain or sea spray. Change lenses in a sheltered place and keep the mount clean. Remove loose grit from the exterior before packing.

There is no image stabilisation in the lens. A camera with body stabilisation can help with shake. Firm support is useful for long interior or night exposures. Moving people can still blur on a tripod, so choose a shutter speed that suits their movement.

Remove loose particles before wiping the front glass. Check for marks when photographing towards bright windows. Keep both ends capped during transport, and dry the exterior before storage.

The optical build uses 15 elements in 9 groups. Two aspherical elements help correct distortion, the fault that bends straight walls into curves. Three low-dispersion elements help reduce colour fringing along high-contrast edges such as a roofline against bright sky.

The autofocus versions have a five-blade aperture. Aperture choice controls both the light admitted and depth of field. Choose the opening for the scene, then check whether the resulting shutter speed needs a tripod or other firm support.
