Product Information

Full details

The Laowa Aksen 17.5mm f1.7 5-10X Ultra Macro APO lens is a precision-engineered optic designed for scientific, industrial, and creative macro photographers who require extreme magnification capabilities. Its standout feature is the Coaxial Illumination (CI) port, which provides shadow-free lighting for reflective or flat subjects. While it offers unparalleled detail retrieval for Nikon Z systems, the lens is a specialized tool that requires a steep learning curve and steady tripod support due to its high magnification levels.

FAQs

Can I use this lens for handheld photography?

It is not recommended. At 5x to 10x magnification, even microscopic movements cause significant image blur. A sturdy tripod or macro rail is required.

Does this lens provide autofocus?

No, the Laowa Aksen 17.5mm is a manual focus lens designed for high-precision photography.

What is the purpose of the Coaxial Illumination port?

It directs light through the lens itself, allowing you to illuminate subjects from the same angle as the camera sensor, which removes shadows and glare from flat, reflective surfaces.

Is this lens compatible with non-Nikon Z cameras?

This specific model is designed for the Nikon Z mount. Usage on other systems would require a third-party mount adapter, which may affect infinity focus or electronic communication.

Does the working distance change as I zoom from 5x to 10x?

No, the working distance remains fixed at 22.5mm throughout the entire zoom range.

Troubleshooting

Image appears blurry across the entire frame

Ensure your camera is mounted on a stable, vibration-free tripod and double-check that your subject is exactly 22.5mm from the front element.

Uneven lighting when using the CI port

Verify that your fiber optic light source is fully seated in the CI port and that the light is centered within the optical path.

Chromatic aberration visible in high-contrast areas

While the APO design minimizes this, ensure you are stopping down to the optimal aperture for your specific lighting conditions to maintain maximum sharpness.

Pros and Cons

Pros

  • Unrivaled 5x to 10x magnification range
  • Coaxial illumination eliminates difficult reflections
  • Apochromatic design ensures minimal color fringing
  • Parfocal design simplifies magnification adjustments during sessions

Cons

  • High magnification levels make handheld use nearly impossible
  • Specialized tool requiring significant lighting expertise
  • Strict working distance requires precise subject positioning

Setup, Compatibility & Care

To begin using the lens, mount it to your Nikon Z camera body using the standard bayonet connection. Ensure your camera is set to Manual Focus mode, as this is a manual lens. For the Coaxial Illumination feature, attach a compatible fiber optic light source to the CI port on the side of the lens barrel. When handling the lens, avoid touching the exposed front element, as the small working distance makes it susceptible to smudging. Keep the lens in a dust-free environment when not in use, and store it in a padded case to protect the complex internal focusing mechanisms from shock or vibration.
