See life in the widest angles possible thanks to the Fujifilm GF 23mm f/4 R LM WR Super Wide-Angle Lens. This lens is a powerful ultra-wide-angle prime lens with a 35mm format equivalent of 18mm and an amazing 99.9 degree angle of view. Distortion is kept to a minimum despite the super wide-angle view while the bright f/4 maximum aperture gives you sharp and clear images even in low light conditions. Intuitive Design The Fujifilm GF 23mm f/4 lens was built to keep up with the highest performance processor in the world. The optical design features 15 lens elements in 12 groups, including 2 aspherical elements, 3 ED (extra-low dispersion) elements and 1 Super ED element to thoroughly suppress chromatic aberrations. This means your images will achieve high resolution performance from edge-to-edge. Tough and Durable The lens has been sealed in nine areas, allowing you to shoot with confidence and stability, even in dusty environments and in light rain outdoors. Advanced Autofocus Thanks to the inner focusing system being used to lighten the weight of the focus lens, the autofocus is fast, quiet, and accurate. The high speed AF provides a versatile shooting experience. Sharper Images The f/4 maximum aperture produces extremely sharp results. Special Nano GI coating is applied to the lens that effectively eliminated unwanted ghosting or flaring.
