Product Information

Full details

The Laowa Aksen 17.5mm f1.7 5-10X Ultra Macro APO lens is designed for macro photographers and scientific researchers who require extreme magnification without sacrificing image quality. Its standout benefit is the parfocal internal zoom mechanism, which allows for magnification changes between 5x and 10x while keeping the subject in focus at a consistent 22.5mm working distance. While this lens offers exceptional precision, it is a specialized tool that requires a steady hand or a macro rail system due to the extreme sensitivity of such high magnification levels.

FAQs

Does this lens have autofocus?

No, this lens is strictly manual focus, which is standard for ultra-macro photography at these magnification levels.

Can I use this for portrait photography?

No, the lens is designed exclusively for extreme macro work with a fixed working distance and cannot focus on subjects at normal distances.

Does the magnification change impact exposure?

Yes, as with all macro lenses, moving toward higher magnification may require adjusting your lighting or exposure settings to compensate for light fall-off.

What is the benefit of the APO design?

APO (Apochromatic) correction minimizes color fringing, ensuring that high-contrast edges in your macro images remain sharp and color-accurate.

Is it compatible with non-L-mount cameras?

This specific variant is designed for L-mount systems; using it on other systems would require a specialized adapter, which may limit functionality.

Troubleshooting

Image appears blurry at high magnification

Ensure you are using a sturdy tripod and a focus rail; at 10x, even the smallest vibration or mirror slap can cause motion blur.

Subject is too dark

The extreme magnification and long bellows extension require significant light; use an external macro flash or specialized LED ring light.

Difficulty finding focus

Set your magnification to 5x first to locate the subject, focus, and then zoom into 10x to refine the details.

Pros and Cons

Pros

  • Maintains focus while adjusting magnification
  • Excellent chromatic aberration control via APO elements
  • Lightweight and portable for an ultra-macro lens
  • Consistent working distance simplifies lighting setups

Cons

  • Very shallow depth of field at high magnification
  • Requires high-precision focus rails for best results
  • Limited to extreme close-up photography only

Setup, Compatibility & Care

This lens is specifically designed for the L-Mount system. To set up, attach the lens to your L-Mount camera body and ensure your camera is set to Manual Focus mode, as autofocus is not supported due to the nature of extreme macro photography. When shooting, use a tripod or a dedicated focus rail system to stabilize your camera. Keep the front element clean using a lens blower and high-quality microfiber cloth, as dust on the front element becomes highly visible at 10x magnification. Always store the lens in a humidity-controlled environment to prevent fungus growth, which is a common risk with specialized glass optics.
