Nikon AF-S NIKKOR 50mm F/1.4G

The AF-S NIKKOR 50mm f/1.4G is a standard prime for Nikon F cameras. It covers full frame and was introduced in 2008. Its fixed view suits portraits, street scenes and everyday interiors. Check whether that framing fits your intended subjects, especially where walls or barriers limit movement.

The f/1.4 maximum aperture is the main draw for dim rooms and evening light. The trade-off is the fixed focal length. You change position to adjust framing, so plan around the space available. A different lens may be useful when subjects move beyond the view you need.

The lens weighs 9.9 oz (280 g) and measures 2.89 in (73.5 mm) across and 2.13 in (54 mm) long. Its short body takes little space in a small kit. Screw-in filters attach directly to the 58mm front thread. Allow room for the hood and caps when packing it beside a camera body.

The f/1.4 maximum aperture admits more light than a smaller opening. At a given shutter speed, it can allow a lower ISO indoors or after dark. Available light still determines the exposure settings needed. Stop down when more depth of field is required, then check the resulting shutter speed.

At close portrait distances, depth of field can be shallow with the aperture wide open. Place focus carefully on the important eye. A subject can stand out against a soft background when there is enough separation behind them. The amount of blur also depends on distance.

On full frame, 50mm gives a standard view for people and everyday scenes. How much fits depends on where you stand. Moving closer makes the subject larger and changes perspective, with near features becoming larger relative to the background. Check the borders for distractions after changing position.

Closest focus is 1.5 ft (45 cm), measured from the sensor, with 0.15x maximum magnification. This range can help with meals, flowers and objects on a table. The minimum distance is not the clearance ahead of the glass. Leave room for light and check that the camera does not shade the subject.

There is no image stabilisation in the lens. Choose a shutter speed that suits both camera shake and subject movement. Firm support is useful for long exposures of still scenes, but a person can continue to move. Inspect a test frame when working in dim light.

Keep the lens sheltered from rain, dust and sea spray. Protect the open mount during lens changes. Remove loose particles before wiping the front glass, and keep both ends capped during transport. Dry the exterior before storage after a damp session.

The optical design uses eight elements in seven groups. The focus ring allows manual adjustment when needed. Check the important detail before a sequence, particularly at close range with a wide aperture. A small change in subject or camera position can require a fresh focus adjustment.
