The Sigma 18-35mm f/1.8 DC HSM lens is the first lens for APS-C cameras to deliver a constant f/1.8 across the zoom range. Here are some sample images and hands-on previews of this awesome lens.

Most people changing formats from APS-C to full-frame are likely to find themselves buying 24- or 28-70mm F2.8 zooms, as such a lens makes it easy to access the larger format’s low-light and shallow depth-of-field capabilities. The key to understanding the Sigma 18-35mm F1.8 is to realize that it gives the same control over depth-of-field as a 28-50mm F2.8 would on a full-frame camera – it also allows you to shoot at wider apertures in any given situation, effectively cancelling out the greater low-light ability that a larger sensor would otherwise give. And, especially if you own a high-end APS-C camera, that can help to reduce some of the motivation for moving to full-frame.
Overall the Sigma seems extremely promising and I’ve been pretty pleased with the results[…] Its range means it’s unlikely to be the ‘one lens to rule them all’ for many people, but if I were an owner of an APS-C DSLR that I liked, this might help dispel the idea that APS-C is somehow just a stepping-stone to the quasi-mythically ‘optimal’ full-frame format (an idea Nikon and Canon have no incentive to challenge). The fact remains that APS-C is by far the most widely-used format in the DSLR era, and this lens could help strengthen the cost/size/flexibility proposition that it offers.
The Sigma 18-35mm ƒ/1.8 DC HSM “A” lens packs a big punch in features and image quality without a big punch to the wallet. Shockingly sharp images at all apertures, even at ƒ/1.8, with excellent flatness of field and good control over chromatic aberration, distortion and vignetting make this lens a no-brainer for users of APS-C cameras looking to upgrade from their kit lens. Furthermore, the lens has excellent built quality with smooth zoom and focus actuation and a nice, hefty heft to it that brings to mind the feel of high-end professional-level zoom lenses. With a super-fast constant ƒ/1.8 aperture that produces surprisingly great images, packaged with excellent build quality, and at the same time having a price that dramatically undercuts the competition, the new 18-35mm ƒ/1.8 DC HSM “A” is sure to become a top seller for Sigma.

As with any Art Lens from Sigma, the build quality is solid. We’re actually quite surprised at it. Personally, I’ve noticed that many people look down on APS-C lenses because they cannot use them on Full Frame cameras later on. But for what it is worth, the build quality combined with the fast aperture has made Sigma a lens maker that is helping to push the notion that people can be totally okay with just an APS-C camera. Fujifilm and Metabones are similar in this thought process.
