The Sigma 18-35mm f/1.8 DC HCM is a technological marvel, because it is the first zoom lens in history with such a wide / fast aperture. Is it still worth buying in 2022Subscribe to Join the Journey. Sigma 18-35mm F1.8 Art DC HSM Lens for Pentax (Renewed) 649. A Review of the Sigma 18-35mm f1.8 ART Lens. Lens Description: The Sigma 18-35mm f/1.8 DC HSM is the first zoom lens ever to achieve a maximum aperture of f/1.8 throughout the zoom range. For 35mm shooting, the company's full-frame 35mm 1.4 DG HSM lens is a little sharper, but if you need the flexibility of a zoom it's worth the convenience trade-off. The Sigma 18-35mm f/1.8 is the world’s first constant aperture f/1.8 zoom lens. To solve this decades-long dilemma, SIGMA proudly introduces the 18-35mm F1. The 18-35mm is ideal for landscapes, portraits, still life, snap shots, casual, and close-ups Buy this product as Renewed and save 100.00 off the current New price. Its nine-bladed aperture renders beautiful out-of-focus areas, and I didn't see any vignetting.
The edge-to-edge sharpness at both ends looks good, too. There's some aberration (fringing) on both sides at 18mm and in the center at 35mm f1.8, but at 18mm it's quite sharp in the center from wide open to f11, and as expected gets a little soft at f16 at 35mm it's sharp from f2.0 to just under f16 as well. Its image quality is generally excellent.

The manual-focus ring has a nice feel for gradual focus, however. In this light, the Sigma 18-35 f/1.8 makes a whole lot of sense. This isn't a noisy lens for video autofocus, but it is a slightly slow mover in conjunction with continuous AF. My coarse metric for performance when shooting stills is the profanity factor, as in how often I find myself epitheting "Why are you so slow?" I don't remember cursing the lens out at all it kept up with my primary test camera, the 7D, pretty well. It's also supported by Sigma's optional USB dock, which allows you to manage and configure lenses and firmware updates. Of course, this isn't an issue for Sony bodies that use sensor-shift stabilization. If you shoot video without a rig, it's essential. I know it's rare to have optical image stabilization in wide-angle lenses (and many manufacturers will tell you it's unnecessary), but I really would like it.

It's not a particularly feature-rich lens - aside from the manual/auto focus switch there's a distance readout window for the manual focus and focal-length indicators for the zoom ring, but that's about it.
