Classic Focal Length

The 90mm focal length is a flattering choice for portraits, offering a natural sense of compression that isolates subjects without distortion. With an angle of view of 27°, it works equally well for headshots, upper-body framing, and artistic detail shots, while its modest f2.8 aperture supports shallow depth of field without increasing the overall size or weight of the lens.

Refined Optical Performance

A carefully arranged formula of 11 elements in 10 groups includes five SLD elements and one aspherical element, improving sharpness and reducing aberrations across the frame. The Super Multi-Layer Coating helps preserve contrast and colour accuracy by minimising flare and reflections, particularly in backlit conditions.

Premium I Series Build

As part of Sigma’s I Series, the lens uses an all-metal barrel with precision-cut aluminium parts and finely knurled controls. The aperture ring includes an auto ‘A’ setting for seamless switching between manual and camera-controlled exposure. The included magnetic metal lens cap adds modern convenience, with compatibility for the optional CH-11 cap holder.

Ready for Travel and Everyday Shooting

Measuring just 64 x 59.7mm and weighing only 295g, the lens is designed for photographers who need sharpness and quality without the bulk. The internal AF system with a stepping motor supports stills and video work, while its weather-resistant structure adds confidence when shooting outdoors or on the move.

FAQs

Is the Sigma 90mm f2.8 DG Contemporary Lens suitable for video?

Yes, the internal focusing system uses a stepping motor that delivers smooth and quiet autofocus, which is especially useful for video. Its compact design also makes it a good fit for handheld or gimbal setups, and the minimal focus breathing helps maintain framing during focus pulls.

How does the build quality compare to other Sigma lenses?

As part of the I Series, the Sigma 90mm f2.8 DG Contemporary features a premium all-metal build inspired by Sigma’s Cine lens range. The knurled rings, magnetic lens cap, and high-quality finishes offer both durability and a professional tactile experience uncommon in compact lenses.

Can I use this lens for macro-style close-ups?

While not a true macro lens, the Sigma 90mm f2.8 offers a respectable 0.2x maximum magnification and a minimum focusing distance of 50cm. This makes it well-suited for tight portrait framing, detail shots, and selective compositions that benefit from its compressed field of view.

What kind of weather resistance does this lens have?

The lens includes a dust- and splash-resistant construction, which adds protection when shooting outdoors or in unpredictable environments. While not fully waterproof, it offers peace of mind for general travel, street, and landscape use in light rain or dusty conditions.

Is the magnetic lens cap reliable for field use?

Yes, the included magnetic metal cap provides a snug and secure fit, making it fast to attach and remove. For users concerned about losing the cap, Sigma offers the optional CH-11 Magnetic Cap Holder, which attaches to your bag or strap for convenient storage.
