Viltrox AF 50mm F1.4 Pro

The Viltrox AF 50mm F1.4 Pro is a standard prime for full-frame cameras, with Sony E and Nikon Z versions. Choose the mount made for your camera. Its fixed view suits portraits, street scenes and everyday photographs. Check whether that framing fits the spaces where you usually work.

Viltrox introduced the Sony E version in 2025. The main trade-off is the fixed focal length: you change position to adjust framing. Walls, tables and barriers can limit that movement. There is also no stabilisation inside the lens, so consider the camera body and support you will use.

The Sony E version weighs 1 lb 12.2 oz (800 g) and measures 3.33 in (84.5 mm) across and 4.37 in (111 mm) long. The Nikon Z version is heavier and longer. Allow room for the hood and caps when packing. A tripod can take the weight during a fixed portrait or product session.

The front takes screw-in filters, which must match the 77mm thread. A neutral-density filter lets you keep the wide aperture in bright light.

On full frame, 50mm gives a standard view of people and their surroundings. 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.

The f/1.4 maximum aperture admits more light than a smaller opening. At a given shutter speed, it can allow a lower ISO in dim interiors or evening streets. A close subject can have a soft background when there is enough space behind it. Focus carefully on the detail that matters.

Closest focus is 1.5 ft (45 cm), measured from the sensor. This range can help with flowers, meals and tabletop objects. Leave room ahead of the glass for lighting and avoid shading the subject. Stop down when more depth is needed, then check the resulting shutter speed.

There is no image stabilisation in the lens. A camera with body stabilisation can help with shake. Firm support helps during long exposures of still subjects, but moving people still need a suitable shutter speed.

The body is designed to resist dust and moisture. Use cover in persistent rain and protect the open mount during lens changes. Dry the exterior before storage after a damp session.

A water-resistant coating on the front glass helps with cleaning. Remove loose grit before wiping the surface, and check for fingerprints when photographing towards a bright lamp.

The optical path holds 15 elements in 11 groups. One aspherical element helps correct distortion and spherical aberration, faults that can bend straight lines or soften a wide-open image. Three low-dispersion elements help reduce chromatic aberration, the colored fringes that can appear along high-contrast edges in backlit portraits.

Internal focusing keeps the barrel length unchanged, so the lens stays the same size throughout the focus range.
