Macro lens for smartphone Ulanzi CL-003 — 10x magnification, 5 elements/5 groups, aluminium, Ø 46 mm, length 31 mm

The Ulanzi CL-003 macro lens for smartphone delivers up to 10x magnification in a compact aluminium body. Designed for close-up mobile photography, the lens assembly uses 5 elements in 5 groups to reproduce fine detail and textures when shooting small objects, surfaces and insects. With a diameter of 46 mm and a length of 31 mm, the lens is lightweight and easy to mount on compatible phone clip systems or threaded smartphone cases that accept 17 mm fittings.

Advantages

The optical design of 5 elements in 5 groups provides controlled image rendition for high-magnification close-ups while helping to minimise aberrations. The aluminium housing combines durability with low weight, making the lens convenient to carry and handle during handheld shooting. The CL-003’s short closest focusing distance (approx. 0.045 m) enables extreme close focusing for capturing minute subjects and surface detail. Constructed to work with standard 17 mm clip or threaded mounts, it integrates with common smartphone mounting accessories.

How to use

Attach the macro lens to your smartphone using a compatible 17 mm clip or a threaded phone case that accepts 17 mm lenses. Position the phone so the lens is aligned with your camera module, then move the phone closer or farther from the subject to achieve focus; the closest recommended focusing distance is approximately 0.045 m. Use steady support or a tripod/phone clamp where possible to reduce camera shake at high magnification. Adjust exposure and focus using your phone’s camera app or a manual camera app to fine-tune image sharpness and brightness.

Usage recommendations

For best results, illuminate the subject evenly with a diffuse light source to avoid harsh shadows and highlights. At high magnifications, even small movements affect focus and framing, so stabilise the phone and consider using touch-to-focus or manual focus controls. The CL-003 is intended for close-range detail work rather than general wide-angle shots; pair it with a stable clip or threaded case and check compatibility with your smartphone camera position before extended use.
