Optical Quality

The Nikon 50mm f/1.4 AI-S has a fast maximum aperture of f/1.4, which makes it excellent for low-light photography and shallow depth-of-field portraits. The lens has seven elements in six groups and uses Nikon’s Super Integrated Coating to reduce flare and ghosting. It produces sharp images with excellent contrast and colors. Bokeh is also pleasing and smooth, thanks to the nine-bladed aperture diaphragm.


The lens performs well in a variety of shooting situations. It is excellent for portraits, street photography, and low-light situations. The manual focus requires some practice, but once you get used to it, you can achieve precise focus. The lens does not have image stabilization, so using a tripod in low-light situations is recommended to avoid camera shaking.
