Sigma 35mm F1.2 DG II Art

The Sigma 35mm F1.2 DG II Art is a fast prime for full-frame cameras. Sigma released it in 2025, and it is still in production. It comes in Sony E and Leica L versions, so pick the one that matches your system.

The 35mm focal length suits reportage, weddings and environmental portraits, where context around the subject matters. The main trade-off is bulk. An F1.2 aperture requires large glass, so this lens is heavy and carries no stabilisation. If you shoot in dim venues and value shallow focus over portability, that trade may suit you.

The lens weighs 1 lb 10.6 oz (755 g), which is noticeable during long hand-held sessions at a wedding. The body is 3.19 in (81 mm) wide and 4.39 in (111.4 mm) long. A screw-in filter attaches directly to the 72mm thread, so any filters you buy must match that size.

On a full-frame camera, 35mm frames a person together with some of their surroundings. That makes it useful for candid event coverage and street work, where stepping back would lose the context. Indoors, the view keeps working in rooms where longer lenses would push you against a wall. You also stay close enough to talk with your subject while you shoot.

The F1.2 aperture is the defining feature. It admits much more light than a smaller opening would, so shutter speeds stay usable in dim reception halls without pushing ISO high. Open at F1.2, depth of field is very shallow, so a face stands apart from a busy background. Stopping down a little restores enough depth to keep both eyes sharp.

Eleven aperture blades keep the opening close to round when you stop down. Out-of-focus lights in a night scene then render as smooth circular shapes rather than obvious polygons. The lens also focuses as close as 0.9 ft (28 cm), near enough for a tight face or a small still-life subject.

Maximum magnification is 0.19x. The optics specification score is 91 out of 100.

Weather sealing is fitted. It helps keep dust and moisture away from the internals during long outdoor shoots, which suits wedding and travel work in changeable weather.

There is no built-in stabilisation, so you will rely on a steady hold or a faster shutter speed in dim light. A monopod or tripod steadies the camera for static scenes such as interiors or posed portraits. The features specification score is 32 out of 100.

The glass also lacks a fluorine coating, so cleaning follows ordinary care. A blower and a soft cloth deal with dust and fingerprints.

Four of the elements have aspherical surfaces, and their shapes help reduce distortion and spherical aberration. Those faults can curve straight edges and soften detail, which matters most when the frame includes buildings, common in street and travel work.

Focusing is internal, so the movement happens inside the barrel as you focus closer.
