The Sigma 45mm f/2.8 DG DN Contemporary is one of the first Sigma lenses to be created specifically for full-frame mirrorless cameras. Lightweight and portable but without compromising on image resolution, the lens has a manual aperture control ring and a build quality, intended to stand up to the rigours of daily use.

45mm Prime Lens for Full Frame Mirrorless

Although 45mm is a standard focal length, the lens from sigma is anything but, with excellent image quality and a super compact form factor that all but guarantees it a spot in your camera bag. The lens is optimised for full-frame mirrorless cameras, especially those with ultra-high-resolution sensors, and can produce razor sharp results.

Bright f/2.8 Aperture

With a bright f/2.8 aperture, the lens can capture more light, especially useful when it’s a little bit darker. When opened up to create a stunningly shallow depth of field, the 7 aperture blades inside the lend form a rounded diaphragm that produce a classical subdued and swirly bokeh giving your images a 3-dimensional look.

High-Resolution Optics

At the other end of the spectrum, when stopped down the lens is incredibly sharp, making it a perfect match for high-resolution images sensors. The impressive resolution uses 8 glass elements, arranged in 7 groups to deliver sharp results and controls spherical aberrations. The optical design also minimises flare and ghosting to capture images with excellent detail and contrast.

Improved Manual Handling

Boasting a classic manual aperture control ring with a satisfying click the lens barrel has an all-metal construction, as does the lens hood. Not only does this add to the ruggedness and robust design of the lens but also highlights the style and class of this excellent lens.

24cm Minimum Focus Distance

The 45mm lens is a great walk-around lens, perfect for street shooters and portraiture. It has an excellent close focusing ability of only 24cm so you can fill the frame with your subject, without worrying about blurry shots.

High-Speed Autofocus Performance

With a high-speed stepping motor, the Sigma 45mm f/2.8 is compatible with cameras with Eye-AF and delivers excellent autofocus performance when shooting video. The snappy autofocus adds to the versatility of the lens, improving your chances of getting sharp in focus shots.

Super Compact Dust a Splash Proof Design

The Sigma 45mm Contemporary f/2.8 DG DN for Mirrorless cameras is an elegant fusion of portability, style and performance. It weighs only 215g, in spite of its rugged metal construction and has a brass mount for improved durability.
