Nikon AF-S DX NIKKOR 18-140mm F/3.5-5.6G ED VR

The AF-S DX NIKKOR 18-140mm F/3.5-5.6G ED VR is an all-in-one zoom for Nikon F mount cameras with the APS-C sensor. Its 18–140mm span runs from wide views to a long telephoto reach in a single barrel.

That range suits travel, family days out and walkabout photography, where one lens must handle landscapes, portraits and distant detail alike. The main trade-off is aperture. The maximum opening drops from f/3.5 at 18mm to f/5.6 at 140mm, so the long end needs more light.

Nikon introduced this lens in 2013, and it remains in production. It stays a straightforward choice for DX body owners who want one lens for varied everyday subjects.

At 1 lb 1.3 oz (490 g), the lens stays manageable for a day of walking and shooting. The body measures 3.07 in (78 mm) across and 3.82 in (97 mm) long.

A screw-in filter must match the 67mm thread on the front. That is a common size, so filters are easy to find.

The 18mm wide end suits interiors, group portraits and streets where you cannot step back. At 140mm, distant subjects fill the frame, which helps at sports grounds, wildlife parks and candid portraits from a distance. Because this is an APS-C lens, the telephoto end frames subjects more tightly than it would on a full-frame body.

The maximum aperture changes with zoom position. At 18mm you get f/3.5, which helps in dim rooms and evening streets. Zoom in to 140mm and the widest opening becomes f/5.6. Indoors at the long end, you will lean on higher ISO settings or the stabilisation. Outdoors in daylight, the smaller opening matters much less.

Focus reaches as close as 1.5 ft (45 cm). That lets you fill the frame with flowers, food or market details without changing lenses. The maximum magnification reaches 0.23x, enough for record shots of objects and textures on your travels.

Aperture choice also shapes backgrounds. Wide open at f/3.5, close subjects separate more softly from their surroundings; stopped down, scenes render crisply front to back.

The VR system steadies the image and allows slower shutter speeds when you shoot handheld. This helps most at the 140mm telephoto end, where small hand movements show up clearly, and in dim interiors at 18mm. It counters your own camera shake, so it suits static subjects rather than fast motion. Many travel scenes, from dim cathedrals to evening markets, fall into that category.

There is no zoom lock, so gravity can pull the barrel down when the lens hangs from a strap. Weather sealing is absent as well, so keep the camera sheltered in rain, spray or dust.

The design includes aspherical elements and low-dispersion glass. Aspherical surfaces help correct distortion, which can bend straight edges in wide shots such as building interiors at 18mm. The low-dispersion glass helps reduce chromatic aberration, the coloured fringes that can appear along high-contrast edges such as branches against a bright sky.
