Product Information

Full details

The Laowa Aksen 17.5mm f/1.7 5-10X Ultra Macro APO lens is a precision-engineered tool designed for scientific researchers, industrial inspectors, and macro photographers who require extreme magnification between 5x and 10x. By utilizing built-in coaxial illumination, this lens excels at capturing fine details on flat and reflective surfaces without the distraction of angled glare or shadows. While it offers unparalleled optical clarity through its apochromatic design, users should note that its specialized nature and fixed working distance make it less versatile for general-purpose photography and best suited for controlled studio or lab environments.

Extended Product Information

FAQs

Can I use this lens for landscape photography?

No, this lens is strictly designed for extreme macro photography between 5x and 10x magnification and will not focus at infinity.

Does the coaxial illumination come with a power supply?

The coaxial illumination system is designed to integrate with the lens structure; please refer to the specific power requirements listed in your product manual for the light source interface.

Do I need an adapter for my Canon RF camera?

No, this lens features a native Canon RF mount for seamless integration.

What is the benefit of the APO design?

The APO (Apochromatic) design uses special glass elements to bring three wavelengths of light into focus on the same plane, virtually eliminating color fringing.

Is the working distance the same at 5x and 10x?

Yes, the lens maintains a consistent 22.5mm working distance throughout the magnification range.

Troubleshooting

Image appears blurry or soft at high magnification.

Verify that your subject is perfectly flat and within the 22.5mm working distance; use a high-quality tripod to eliminate all vibrations.

Uneven lighting or shadows present.

Check the alignment of the coaxial light source to ensure it is centered correctly along the optical axis.

Camera does not detect the lens.

Ensure the lens is fully locked into the Canon RF mount and wipe the camera-to-lens contacts with a clean, dry microfiber cloth.

Pros and Cons

Pros

  • Superior illumination control through integrated coaxial lighting
  • High-resolution imaging with reduced chromatic aberrations thanks to APO optics
  • Consistent working distance simplifies complex macro photography workflows
  • Solid mechanical build suitable for industrial and laboratory settings

Cons

  • Specialized design limits the lens to high-magnification macro work only
  • Requires specific lighting conditions to maximize coaxial illumination benefits
  • Fixed, short working distance requires precise subject placement

Setup, Compatibility & Care

To begin, attach the Laowa Aksen 17.5mm lens directly to your Canon RF mount mirrorless camera. Ensure the electronic pins are clean to allow for proper communication. Since this is a manual focus lens, utilize your camera's 'Focus Peaking' or 'Magnified View' features to confirm sharpness before capturing your subject. Regarding care, always keep the front element clean as the extreme magnification makes even tiny dust particles visible. Store the lens in a humidity-controlled environment, and ensure the coaxial light source is disconnected when not in use to prolong the lifespan of the illumination system.
