Nikon's original AF fast fifty — the AF 50mm f/1.4 that launched Nikon's autofocus era.
The Nikon AF Nikkor 50mm f/1.4 was released in 1986 as part of Nikon's original AF lens lineup. It is the autofocus version of Nikon's classic fast fifty, providing f/1.4 speed with the convenience of autofocus. The screw-drive AF design uses the camera body's AF motor. Multiple versions exist with minor updates across the production run.
Optical performance is good with vintage character. Sharpness is soft at f/1.4 with a pleasant glow, improving dramatically by f/2. By f/4, the lens is very sharp across the frame. Bokeh is smooth with seven aperture blades. The wide-open rendering has character that many portrait photographers find appealing. The screw-drive AF is functional but noisy.
Nikon F mount with D-type coupling. Filter thread is 52mm — compact. Weight is approximately 230 grams — very lightweight. Build quality is good with a solid feel. The screw-drive AF requires a body with built-in motor — will not autofocus on D3xxx/D5xxx bodies. The later AF-S 50mm f/1.4G with silent wave motor is the upgrade path.
Common and affordable on the used market. Check AF accuracy and smooth focus ring. The screw-drive limitation restricts body compatibility. An excellent budget fast fifty for Nikon shooters with compatible bodies. The soft f/1.4 rendering has character. The AF-S 50mm f/1.4G is preferred for entry-level body compatibility.
