Viltrox AF 27mm f/1.2 Pro

The Viltrox AF 27mm f/1.2 Pro is a bright prime for APS-C mirrorless cameras, introduced in 2023. Viltrox makes it in Fujifilm X, Nikon Z and Sony E mounts, so choose the version that matches your camera.

The 27mm focal length suits walk-around photography and everyday scenes. The f/1.2 aperture gathers light for that work indoors and after dark. Restaurant tables, night markets and candlelit receptions all sit within its reach.

That brightness costs size, and the lens carries no stabilization. It suits photographers who want a fast everyday prime and can carry the extra bulk.

The Fujifilm X version weighs 1 lb 3.8 oz (560 g) and runs 3.62 in (92 mm) long; other mounts differ. Every version measures 3.23 in (82 mm) wide, a chunky presence on a compact APS-C body. A screw-in filter must match the 67mm front thread.

On an APS-C sensor, 27mm frames scenes at a moderate, everyday angle. That makes it a natural choice for street photography, travel, interiors and environmental portraits, where you want context around the subject. Step closer to tighten a composition, or back away to include more of the setting.

The f/1.2 maximum aperture is the key optical specification. It gives more room for a faster shutter speed or lower ISO than a smaller opening. A nearby subject can have a soft background when there is space behind it. Stop down when detail at several distances must stay sharp, and check focus carefully on the main subject.

Closest focus is 0.9 ft (28 cm), measured from the sensor. This allows nearby details such as food or tabletop objects with some surroundings included. Leave room ahead of the front glass and avoid shading a small subject as you move close.

The Optics specification scores 91/100. As a prime, it offers one focal length, so you frame by moving yourself rather than turning a zoom ring.

The lens is sealed against dust and moisture. That suits changeable outdoor conditions, from a dusty street market to damp air near the coast.

The fluorine coating helps water and oily marks wipe away from the front glass. Remove loose grit before wiping, especially after working in a dusty place. Keep the front covered during transport.

There is no stabilisation in the lens. A camera with body stabilisation can help reduce shake for still scenes. Firm support offers another option for longer exposures. For moving people, retain enough shutter speed for their movement too.

The design includes aspherical and low-dispersion glass. Aspherical surfaces help correct distortion, which can bend straight edges, and spherical aberration, which can soften detail. Low-dispersion glass helps reduce chromatic aberration, the coloured fringes that can appear along high-contrast edges such as a backlit face against bright sky.

Focusing is internal, so the barrel length stays constant as focus changes, even at the 0.9 ft (28 cm) minimum.
