Product Information

Full details

The Laowa Aksen 45mm f/2.8 1-5X Ultra Macro APO lens is a precision-engineered tool designed for macro photographers and scientific researchers who require extreme magnification without compromising image quality. By offering a constant 40.35mm working distance across its entire 1x to 5x magnification range, it removes the need for constant lens repositioning, though its manual-focus-only nature requires a steady hand and practice for optimal results.

FAQs

Does this lens support autofocus?

No, the Laowa Aksen 45mm is a manual focus lens only.

Can I use this for portrait photography?

While it is technically possible, this lens is optimized specifically for extreme macro work and lacks the focal length and aperture characteristics ideal for standard portraits.

Is the working distance truly constant?

Yes, the lens provides a consistent 40.35mm working distance from the front element to the subject across the entire magnification range.

Do I need a flash for macro photography with this lens?

At 5x magnification, the light loss is significant, so using a specialized macro flash or high-intensity constant light is highly recommended.

What is the weight of the lens?

The lens weighs approximately 599g, making it suitable for both handheld and rig-based shooting.

Troubleshooting

Camera does not fire the shutter

Enable the 'Release shutter without lens' setting in your Canon RF camera menu.

Image appears blurry at 5x magnification

Use a sturdy tripod and a shutter release cable to eliminate vibration, as high magnification amplifies even minor movements.

Difficulty finding focus in dim light

Use a dedicated macro LED ring light or a high-intensity focus light to brighten the subject.

Pros and Cons

Pros

  • Constant working distance simplifies subject lighting
  • Excellent control over color fringing via APO optics
  • Highly versatile magnification range
  • Lightweight and portable for field photography
  • Parfocal performance aids in focus stability

Cons

  • Manual focus only, requiring skill for moving subjects
  • No image stabilization
  • Requires significant light due to macro aperture constraints

Setup, Compatibility & Care

This lens is specifically designed for the Canon RF mount. To achieve the best results, use the lens in Manual Mode (M) or Aperture Priority (Av) on your camera. Because the lens lacks electronic contacts for autofocus, you must ensure your camera is set to 'Release shutter without lens' in the custom menu settings. When handling, avoid touching the front element to prevent residue buildup, and store the lens in a humidity-controlled environment to prevent fungus on the specialized APO glass elements.
