Announced today, the 18-50mm F2.8 DC DN Contemporary is Sigma’s first APS-C format zoom lens exclusively for mirrorless cameras. Available in Sony E-mount and L-mount, we recently had the opportunity to try out the lens before its release. Pairing it with the new Sony ZV-E10 camera, we took it for a spin in Prospect Park. Watch the review above or read on below to learn how the lens performed in the field.

Before we get into how the lens performed, let’s discuss the build.  The Sigma 18-50mm F2.8 DC DN measures 2.6 x 2.9 inches (65.4 x 74.5mm) and weighs 10.2 oz (290g). This makes it the smallest and lightest F2.8 zoom lens for mirrorless, APS-C format cameras currently available. It felt like it, too. The lens paired excellently with the similarly compact ZV-E10, and we had no trouble carrying it around all day. Click here to read about five other lenses that work well with this camera. 

Optically, the lens uses 13 elements in 10 groups, with one SLD and 3 aspherical elements. The lens’ diaphragm has 7 rounded blades and an aperture range from F2.8 to F22, while a stepping motor powers its autofocus capabilities. The lens uses 55mm filters, the same as the Sigma 56mm F1.4 DC DN Contemporary.  

While the lens doesn’t have any buttons on switches on its side, it does still look and feel like a premium lens. The barrel construction uses a durable, thermally stable composite that feels like aluminum, while the brass bayonet mount has a dust and splash-resistant structure. Given its affordable $549 price tag, the build of the lens alone promises great value. 


Shooting in Prospect Park with the ZV-E10 and a Zhiyun Crane-2 gimbal, we were able to capture some incredible imagery using the Sigma 18-50mm F2.8.  While we primarily shot at its widest focal length, 18mm, the lens consistently delivered high quality imagery throughout its focal range.  

Shooting in the shade and the early evening, the F2.8 aperture helped the lens deliver optimal results in low light. Additionally, the lens generated smooth, pleasing bokeh at this aperture; a visual quality that added depth and prestige to our photos. 

The lens is also remarkably adept at handling close-up and macro style photography. The lens has a minimum focusing distance of 4.76 inches, maximum magnification ratio of 1:2:8, and working distance of just 1.1 inches. This means you can get very close to your subjects while keeping them extremely sharp, allowing you to capture some breathtaking visuals.  

Sigma lenses generally do a great job of keeping up with the renowned autofocus capabilities of Sony’s mirrorless cameras, and the 18-50mm F2.8 is no exception. The lens had no trouble delivering the extremely fast autofocus promised by the ZV-E10.  

Should I Buy the Sigma 18-50mm F2.8 DC DN Contemporary Lens?  

The Sigma 18-50mm F2.8 is a fantastic lens. Given its versatility, impressive close-up capabilities, wide maximum aperture and ultra-compact build, $549 is a fantastic price. Available in Sony E-mount and L-mount, this lens should be strongly considered by anyone with a mirrorless, crop-sensor camera.
