A unique tool designed to reveal the beautiful details hidden in tight spaces, the Nikon F-mount 28mm f/13 Macro Probe Lens from AstrHori features a 2:1 magnification ratio and a 13.1" waterproof probe extension with front-end illumination to bring the unseen world to light. The 2x magnification capability enables detailed close-ups, while the extension's slender, 0.9" diameter makes it ideal for fitting through slim openings and into small spaces. The optical design consists of 21 elements in 16 groups and features an aperture range of f/13 to f/40. Taken all together, the wide-angle macro provides a broad depth of field that brings both the subject and its surroundings into focus for environmentally rich imagery.

The lens's durable and protective front element is crafted from sapphire glass, a material known for its hardness and resistance to wear and scratches. The front-end fill light is powered through a USB-C interface and comes with a charging cable.
