Our take on the Sigma 45mm f/2.8 DG DN Contemporary Lens for Sony E

The Sigma 45mm f/2.8 DG DN Contemporary is a compact full-frame prime for Sony E-mount cameras. It is built around smooth, rounded bokeh and a short 9.5-inch minimum focus distance rather than a fast aperture. It suits street, travel and everyday shooters who want a small lens with character. Against f/1.8 and f/1.4 50mm rivals it gives up light gathering and background blur, but it is smaller and lighter and focuses closer.

About the Sigma 45mm f/2.8 DG DN Contemporary Lens for Sony E

The Sigma 45mm f/2.8 DG DN Contemporary is a normal-length prime lens for full-frame Sony E-mount mirrorless cameras. It is part of Sigma's Contemporary line, which balances a compact, lightweight build with optical performance. It can also be used on APS-C models, where it gives a 68mm equivalent focal length.

The lens has a constant f/2.8 maximum aperture and a rounded seven-blade diaphragm. The optical design controls spherical aberrations to produce large, soft, rounded bokeh and a three-dimensional look to the subject. The minimum focusing distance is 9.5 inches, which suits snapshots and tabletop photos.

A stepping motor drives fast, precise, near-silent autofocus, including with Face/Eye Detection AF and during video. Full-time manual focus is also available. The brass bayonet mount has rubber sealing that makes it dust- and splash-resistant. A lens hood is included to protect the front element and reduce flare.

Questions and answers

Is the f/2.8 aperture a problem?
It limits low-light shooting and background blur compared with f/1.8 or f/1.4 primes. In return the lens is smaller and lighter, and it focuses closer than most rivals.
How close can it focus?
The minimum focus distance is 9.5 inches, which is close enough for tabletop and detail shots. That is closer than most 50mm primes.
Does it work on APS-C Sony cameras?
Yes, it mounts on Sony E-mount APS-C bodies, where it behaves like a roughly 67mm lens. It is designed for full-frame sensors.
Is it weather-sealed?
Yes, the barrel has a weather-sealed construction. It is not waterproof, so heavy rain still needs care.
What is in the box?
The lens, the LH577-01 hood, front and rear caps and a limited one-year warranty.
How does it compare with the Sigma 45mm f/2.8 on other mounts?
The optical design is the same; this version is built for Sony E-mount bodies. Autofocus behavior depends on the camera body.
Where is the Sigma 45mm f/2.8 DG DN Contemporary Lens for Sony E cheapest?
At Walmart, for $399.95, 35% under what the other stores charge, as of our latest check.
Where can I buy the Sigma 45mm f/2.8 DG DN Contemporary Lens for Sony E?
16 stores we checked sell it, including Walmart, K&M Camera, Amazon, eBay, Precision Camera and Video.
