Laowa 4mm f2.8 Circular Fisheye Lens - Fujifilm X

The Laowa 4mm f2.8 Fisheye Lens features manual focus only. There is no autofocus.

Yes, its wide 210° angle of view and f2.8 aperture make it well-suited for capturing the night sky. Images can be corrected in post-processing.

You can achieve a 360° panorama by taking just 2-3 overlapping shots and stitching them together using panorama software.

The closest focusing distance is 0.08 meters (8 cm).

'De-fish' refers to the process of correcting the strong distortion inherent in fisheye lenses using software, transforming the circular or ultra-wide image into a more rectilinear (straight-edged) view.

While versatile for creative shots, its extreme fisheye distortion means it's best used for specific applications like ultra-wide landscapes, architectural interiors, or artistic effects rather than everyday general use.

The lens weighs approximately 135 grams (4.8 oz).

Ensure you are using manual focus and have set the focus ring correctly. For distant subjects, set focus to infinity. For close-ups, use the 0.08m minimum focusing distance and adjust carefully.

Avoid shooting directly into very bright light sources. Consider using a compatible lens hood or manually shading the lens with your hand or a card during shooting.

Double-check that the lens is correctly and securely mounted on the Fujifilm X-mount. Ensure your camera firmware is up to date.

This is expected behavior on sensors that don't fully cover the image circle projected by the lens. The resulting image will be circular within the frame. For a full-frame view, de-fishing is required.
