The Nikon Action 10x40 are mid-range standard-sized binoculars similar to the Nikon Action 10-22x50 Zoom XL. Lacking the 10-22x magnification of the 10-22x50 Zoom XLs as well as their 50mm lens diameter, the Action 10x40s offer simple 10x magnification and a somewhat dimmer 40mm lens diameter for those not seeking more advanced features. Otherwise, however, the 10x40s feature the same high quality construction as the 10-22x50 Zoom XLs, including: multi-coated eyepiece lenses, BaK-4 prisms and a porro prism system.

The Action 10x40s' multi-coated eyepiece lenses reduce glare while providing higher contrast images and reducing eyestrain. Their BaK-4 glass prisms provide the Action 10x40 with brighter images and greater clarity from edge-to-edge than typical BK-7 prisms. Additionally, the Action 10x40s' porro prism system provides greater depth perception and a greater field-of-view than roof prism system binoculars by way of an offset front lens.
