FAQs

What is the primary benefit of a fisheye lens?

The primary benefit is its extremely wide field of view, allowing you to capture a much larger scene than a standard lens.

How do I clean the lens?

Use a soft, lint-free microfiber cloth to gently wipe the lens surface. For tougher smudges, a lens cleaning solution specifically designed for optics can be used sparingly on the cloth.

Is this lens suitable for professional, distortion-free video?

No, fisheye lenses are characterized by significant barrel distortion. They are best used when this distortion is desired for creative effect or when the wide field of view outweighs the need for rectilinear images.

What does 'M12 mount' mean?

M12 mount refers to a standard threaded lens mount size commonly used on smaller security and machine vision cameras. It indicates the physical interface between the lens and the camera body.

Can I use this lens on a camera with a different mount type?

No, this lens is specifically designed for Marshall cameras with an M12 mount and will not physically fit or function correctly with other mount types like C-mount or CS-mount.

How does the f/2.2 aperture affect image quality?

The f/2.2 aperture is relatively wide, meaning it allows more light to enter the lens. This is beneficial in low-light conditions and can also produce a shallower depth of field, though the extreme wide-angle nature of the lens often results in a large depth of field overall.

Troubleshooting

Lens won't focus properly

Ensure the lens is securely screwed into the M12 mount. Adjust focus by carefully rotating the lens or camera settings if available. Fisheye lenses have a very large depth of field, so focus issues are rare unless the lens is loose.

Image appears blurry or hazy

Clean the lens element with a microfiber cloth. Check for any protective film that may still be on the lens.

No image displayed on the monitor

Verify that the camera is powered on and correctly connected to the display. Ensure the lens is properly seated on the camera mount.

Pros and Cons

  • Adds a unique, distorted perspective for creative applications.

Cons

  • Produces significant barrel distortion, which may be undesirable for some applications.
  • Image quality can degrade towards the edges of the frame.
  • Not suitable for applications requiring a sharp, rectilinear (straight-line) perspective.
  • Requires careful subject placement to manage distortion.

Setup, Compatibility & Care

Setup:

  1. Ensure your Marshall camera features an M12 lens mount.
  2. Carefully unscrew the existing lens, if any, from the camera body.
  3. Gently screw the Marshall Fisheye Lens onto the M12 mount until snug. Do not overtighten.
  4. Connect the camera to its power source and the appropriate display.
  5. Adjust focus and framing as needed, considering the wide field of view.

Compatibility:

  • This lens is designed for Marshall cameras with an M12 lens mount.

Care:

  • Clean the lens surface regularly with a soft, lint-free microfiber cloth.
  • Avoid touching the lens with bare fingers to prevent smudges.
  • Store the lens in a clean, dry environment when not in use.
  • Use a lens cap (if provided) to protect the front element.
