Aksen series (1–5x and 5–10x) redefines high-magnification macro shooting by eliminating the hassles of traditional lenses. Its groundbreaking parfocal zoom and internal zoom mechanism, the Aksen series has a fixed working distance, meaning you can fluidl


This fixed working distance means you can keep the same lighting setup, framing and composition, making shooting ultra macro easier than ever.
1-5X Magnification range with 40.35mm working distance; 5-10X Magnification range with 22.48mm working distance.

The Aksen's focus remains locked on the subject whether you zoom in or out. Zoom freely from 1X to 5X or 5X to 10X without moving your camera or subject — your entire setup stays perfectly in position.


The Aksen series uses a sophisticated APO design to eliminate Chromatic aberration, provide ultra sharp image with clinical precision and zero wavelength divergence.

The coaxial lighting option opens a new window into creativity.

Reveal the full spectrum of microscopic details invisible to the naked eye — perfectly suited for wildlife photography, product macro imaging, scientific documentation, and creative cinematic close-up cinematography.

With the 1–5X macro lens, the numerical aperture (NA) varies depending on the magnification level in use.

The optional lens collar allows users to mount len directly to tripod instead of camera, providing a vastly superior weight distribution and balance.

Weighing approximately 586g (1–5X) and 569g (5–10X) , these lenses achieve a fine balance between high-magnification stability and everyday portability — allowing creators to shoot freely in the field without being weighed down.
