The Fujinon HF25XA-1F 5MP lens is an 25 mm 2/3" lens with a M25.5 x 0.8 filter size, and -0.07% distortion. All Fujinon HF-XA-1F series lenses features high performance "4DHR" that minimizes degradation of resolution. The lens maintains image sharpness from the center to the edges of the image and produces consistent, high-resolution images while mitigating degradation of resolution caused by changes in the shooting distance or aperture.

HF-XA-1F lenses are built with Fujinon's Anti-Shock and Vibration technology and a rugged mechanical design with no moving parts inside the lens. Anti-Vibration performance has passed vibration tests conforming to IEC60068-2-6. These features enable optical stability and durability even in harsh environments.

Three interchangeable Iris plates are included with the lens: F open, F4, and F8. Users can customize the iris by replacing the iris plate. The plates are screw-locked to ensure they can withstand heavy shocks and vibrations.
