It’s been a while since Sigma last released an f/1.8 zoom lens. The Sigma 18-35mm f/1.8 (buy here) was released back in 2012 and the Sigma 50-100mm f/1.8 (buy here) in 2016. Now, we have a new one. The Sigma 28-45mm f/1.8 DG DN Art (buy here).
Unlike the two previous lenses, which were designed for APS-C DSLRs, this one is for full-frame mirrorless cameras. As one might expect, though, it has a fairly short focal length range, and it’s available for Sony E and Leica L mounts.
Sigma 28-45mm f/1.8 DG DN Art – A full-frame 18-35mm
The Sigma 28-45mm f/1.8 DG DN Art has a fairly limited focal length range. This is the compromise that needs to be made with such a wide aperture. The longer the focal length range at such wide apertures, the larger the lens needs to be. And they can get ridiculously big very quickly. This is why the Sigma 24-70mm f/2.8 DG DN II Art lens (buy here) is f/2.8 and not f/1.8.
The new lens actually provides slightly less range than the Sigma 18-35mm f/1.8, which, if it were a full-frame lens, would offer the equivalent field of view to 27-52.5mm. It’s pretty close-ish, kinda, though, so I think we can expect a very similar look on full-frame bodies to that which we’ve seen with the 18-35mm f/1.8 on APS-C DSLRs – but with a shallower depth of field and not quite as long a reach.
It’s essentially the full-frame mirrorless replacement for the old 18-35mm f/1.8. I suspect this means we won’t ever see an APS-C mirrorless 18-35mm f/1.8, but Sigma may surprise us one day.
At the 45mm end, it offers a maximum magnification ratio of 1:4, thanks to its 11.9″ minimum focus distance. It has an aperture ring with clicks and lock switches and an 11-blade diaphragm. Nano Porous and Super Multilayer Coatings help to eliminate ghosting, flare and aberration.
It features a High-Response Linear Actuator (HLA) motor. Sigma says this offers fast, quiet, and smooth focusing performance. For the Sigma fp and fp L (buy here) shooters, Sigma says the manual focus ring of the L mount version can be set to the linear focus mode for those shooting video.
