Venus Optics Laowa 25mm f/2.8 2.5-5x Ultra-Macro Lens for Nikon F with LED Ring Light

Ultra-macro magnification range

The Laowa 25mm f/2.8 delivers 2.5x to 5x life-size magnification for Nikon F cameras, targeting photographers who need extreme close-up detail beyond standard macro lenses. An included LED ring light mounts to the front of the lens to provide direct subject illumination at these high magnifications. The optical design uses eight elements in six groups with an extra-low dispersion element for corner-to-corner sharpness. This combination suits scientific, nature and product photography where resolving microscopic textures is the priority.

Mount and working distance check

Verify that your camera uses the Nikon F mount before ordering, as this lens is built exclusively for that system. At 2.5x magnification the working distance measures 45mm, while at 5x it reduces to 40mm; ensure these distances suit your subject and lighting setup. The minimum focusing distance ranges from 23.4cm at 2.5x to 17.3cm at 5x, so confirm you can position the camera accordingly. Manual focus operation is required, so consider whether your workflow accommodates precise manual focusing at high magnification.

Thermal noise and power profile

The lens is a passive optical device with no internal electronics, so it generates no heat and produces no audible noise during use. The supplied LED ring light draws power from an external source such as a USB power bank or adapter, keeping the lens barrel itself cool during extended sessions. Because there are no motors or stabilisation units, battery drain on the camera body is unaffected by the lens. The only thermal consideration is ambient temperature affecting the LED output, not the lens performance.
