Product Information

Full details

The Laowa 4mm f/2.8 Circular Fisheye Lens is an ultra-wide, creative prime lens designed for photographers and videographers using L-mount APS-C cameras. It is an ideal tool for creators who need to capture expansive 360-degree panoramas, immersive VR content, or dramatic, exaggerated perspectives in a highly portable 135g package. However, due to its extreme 210-degree circular field of view, users should be prepared for significant image distortion that requires post-processing software for traditional rectilinear correction.

FAQs

Does this lens provide an autofocus function?

No, the Laowa 4mm f/2.8 is a manual focus lens.

Can I use this on a full-frame camera?

The lens is designed for APS-C sensors. You can mount it on a full-frame L-mount camera, but you will experience significant vignetting and will need to crop the image heavily.

How do I remove the fish-eye distortion?

You can use post-processing software like Adobe Lightroom or dedicated 'de-fishing' plugins to map the circular image to a standard rectilinear projection.

Is this lens weather-sealed?

No, the lens does not feature weather sealing. Avoid exposure to rain, dust, or extreme humidity.

How many shots are needed for a 360-degree panorama?

Due to the 210-degree field of view, you can typically capture a full 360-degree environment in just 2 to 3 shots.

What is the closest I can focus?

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

Troubleshooting

Camera does not detect the lens.

Ensure the lens is securely mounted. You may need to enable 'Shoot without lens' or 'Release shutter without lens' in your camera’s custom function settings.

Images appear blurry.

Since the lens is manual focus, use your camera's Focus Peaking or Magnification assist feature to ensure the subject is sharp before taking the shot.

Image is dark in the viewfinder.

Ensure the aperture ring is set to a wider value (e.g., f/2.8) or adjust your ISO and shutter speed to compensate for low light.

Pros and Cons

  • Excellent for creating 360-degree panoramas with minimal frame counts

  • Not compatible with full-frame sensors without aggressive cropping

Setup, Compatibility & Care

This lens is specifically designed for L-mount mirrorless cameras featuring an APS-C sensor. To set up, simply align the red index mark on the lens mount with the corresponding mark on your camera body and rotate clockwise until it clicks into place. As this is a manual lens, ensure your camera's 'Release without lens' setting is enabled in the menu if the camera fails to trigger the shutter. For care, always use a lens cap when not in use to protect the protruding front element. Use a soft, microfiber cloth to clean the glass and store the lens in a cool, dry place to prevent moisture buildup inside the optical elements.
