Sigma has announced two new lenses, the all-new 28-105mm F2.8 DG DN available for L-mount and Sony E-mount, and the 10-18mm F2.8 DC DN for Canon‘s RF mount. 

We’ve already reviewed the latter 10-18mm in Sony’s E-mount – it’s a stunner designed for APS-C mirrorless cameras such as the Sony A6700, with a 15-27mm equivalent focal length ideal for photo and video. And it’s an excellent addition to the otherwise sparse range of lenses for Canon’s best (crop-sensor) cameras like the EOS R7 and EOS R10

However, it’s the 28-105mm lens that’ll grab the attention of professional photographers, many of whom rely on a fast aperture standard zoom lens for a lot of their work, and for whom Sigma’s latest creation appears to offer added versatility.

Sales start date of both lenses is September 26,  with the Sigma 28-105mm F2.8 DG DN’s list price being $1,499 / £1,399, while the Sigma 10-18mm F2.8 DC DN costs $599 / £649 (bear with us while we get Australia pricing).

The new professional zoom lens on the block

Like many pros that shoot a mixture of portrait, weddings, sports and events, I heavily rely on my 24-70mm f/2.8 professional-quality lens. It boasts excellent sharpness from centre to edges, a moderately fast aperture that’s great in low light and for shallow depth of field and consistent across the zoom range , while the 24-70mm range is highly versatile. 

Sigma’s new lens is a slightly different prospect, favoring those that typically like to zoom a little closer. You lose the wide 24mm end – 28mm doesn’t fit nearly as much in your frame and is less versatile for run-and-gun video work for which the wider perspective can often be super helpful. 

However, you get a whole load extra reach as the telephoto end: 105mm to the traditional standard zoom’s 70mm. It’s kind of a nice middle ground between 24-70mm and 70-200mm f/2.8 lenses, and for many users I can see it doing the job of both.

All the while. you still get that f/2.8 aperture across the entire zoom range, unlike other popular standard zoom lenses like the 24-105mm f/4’s that sacrifice the wider aperture in favor of zoom versatility and compact form factor.

Sigma doesn’t skimp on quality with its lenses: the 28-105mm is dust and splash resistant, plus it’s packed extrnal controls such as a clicked / de-clicked aperture ring. 

And although we haven’t tested the lens, its construction of 18 elements in 13 groups and 12 aperture blades bode well for sharp detail and attractive bokeh, as does its High-repsonse Linear Actuator (HLA) inner focus system for fast and reliable autofocus.

It’s a cool news lens that I see being extremely popular, especially with Sigma’s typically competitive pricing versus proprietary lenses. There’s no word yet if the 28-105mm will be made in Nikon Z or Canon RF mounts.
