The Nikon AF Nikkor 50mm 1:1.8D (also known as the Nikon AF Nikkor 50mm f/1.8D) is a versatile, compact, and lightweight prime lens for Nikon F-mount DSLR cameras. It is known for its high image quality and affordability, making it a popular choice for general photography, travel, and portraiture. Key Features and Specifications Focal Length: 50mm (considered a "normal" lens on full-frame (FX) cameras, providing a natural perspective). On a Nikon DX-format (APS-C) camera, it provides an angle of view equivalent to a 75mm lens. Maximum Aperture: f/1.8, which allows for shooting in low light conditions and creating a pleasing, natural background blur (bokeh). Minimum Aperture: f/22. Lens Construction: 6 elements in 5 groups. Diaphragm Blades: 7, contributing to smooth out-of-focus areas. Minimum Focus Distance: 0.45 meters (1.5 ft.). Autofocus: Features a screw-drive autofocus mechanism, meaning autofocus will work on Nikon camera bodies that have a built-in focus motor. On motorless bodies (like entry-level DX cameras), the lens can only be used with manual focus. Filter Size: 52mm. Dimensions (Approx.): 63.5 mm (diameter) x 39 mm (length). Weight (Approx.): 155 grams (5.5 oz), making it very portable. Compatibility: Fully compatible with Nikon FX (full-frame) and DX (APS-C) format cameras, as well as 35mm film cameras. Usage and Performance The AF Nikkor 50mm f/1.8D is widely regarded as a sharp lens that delivers excellent image rendering for its price point. Its bright f/1.8 maximum aperture is a major asset for creative control over depth of field and effective low-light performance. Availability Must have in 2026. Enjoy with Nikon Nikkor
