Nikon AF-S NIKKOR 85mm F/1.4G

Nikon aimed this full frame prime at F-mount portrait photographers, and an 85mm focal length is a natural fit for that work. It also suits indoor events and candid street portraits.

The f/1.4 maximum aperture is the main draw. The trade-offs are a fixed focal length and no built-in stabilisation. You choose a position for the composition and provide a steady hold or support. Nikon introduced this lens in 2010 for its F-mount system.

The lens weighs 1 lb 5 oz (595 g) and measures 3.31 in (84 mm) long and 3.41 in (86.5 mm) across. The weight matters when you carry the camera through a long event. A screw-in filter attached directly must match the 77mm front thread, whether it is a polariser, ND or another type.

At 85mm, you can make a person prominent in the frame from farther away than with a shorter lens. Exact framing depends on distance. A position that allows conversation can help during portraits. For stage work or a ceremony, check the composition from the positions available before the event starts.

The f/1.4 maximum aperture gives more room for a faster shutter speed or lower ISO than a smaller opening. That helps in dim reception halls and theatres. Available light and the speed of a moving person still determine whether the chosen shutter speed is enough.

At close portrait distances, f/1.4 can give a thin zone of sharp focus. A background well behind the subject can become soft. Focus on the eye that matters most, then stop down when more of the face or several people must stay sharp. Nine blades shape the opening.

Closest focus is 2.8 ft (85 cm), measured from the sensor. Anything nearer is too close to focus. If you want a tight composition, check both focus and framing before directing the subject. Moving changes perspective as well as the amount of background included.

There is no stabilisation in the lens. For handheld work in dim venues, the wide aperture or a higher ISO can help you retain a faster shutter speed. A monopod or other firm support can reduce camera movement during slower exposures.

Support does not stop a moving person. At an event, watch for moments when a subject pauses, then choose a shutter speed that fits the movement. Flash can provide another light source when the location and subject permit it.

The front glass has no fluorine coating. That does not describe every coating used in the lens. Remove loose grit before wiping marks and cover the glass during transport. This reduces contact with fingers and objects in a crowded bag.

Nikon uses internal focusing, so barrel length stays unchanged while focus moves. The optical formula contains 10 elements in 9 groups. These totals describe the layout without establishing measured image quality. Internal focusing describes the mechanism; it does not by itself establish focusing speed, tracking accuracy or front-element rotation.
