Nikon Nikkor 24mm f/2.8 Ai - Nikon F Mount

The Nikkor 24mm f/2.8 Ai is a classic wide-angle manual focus lens, notable for being the first Nikon lens to incorporate Close Range Correction (CRC). This system ensures high optical performance even at its minimum focusing distance of 0.3m. It offers a versatile 84-degree field of view on full-frame bodies, suitable for landscape, interior, and documentary photography. The lens construction is robust, featuring an all-metal barrel typical of the Ai era. Prospective buyers should ensure the CRC system is functioning correctly by checking for consistent sharpness across the focus range. We examine the aperture ring for distinct, tactile clicks and check for any signs of oil leakage onto the iris blades. We also inspect the front filter ring for dents, as this model is often used without a hood. SDS ensures the glass is clear of fungus and haze.
