Sigma’s 17-40mm f/1.8 Lens Could Expand the Zoom Range for Your APS-C Cameras

There is big news in the APS-C mirrorless camera world today as Sigma has just announced the successor to one of the company’s most popular zoom lenses of all time. The Sigma 18-35mm f/1.8 DC HSM Art lens for APS-C SLRs is nearly 10 years old at this point, and it’s finally getting a follow-up.The new Sigma 17-40mm f/1.8 DC Art lens is set to expand the zoom range while still offering many of the same optical design principles that you might find in Sigma’s other new full-frame 28-45mm f/1.8 DG DN Art lens.Let’s look at this Sigma 17-40mm f/1.8 DC Art lens and explore what it could offer for your APS-C mirrorless cameras as a go-to lens option for all types of productions and projects.The Sigma 17-40mm f/1.8 DC Art LensDesigned to feature prime-like optical performance and video-friendly functionality, this new zoom from Sigma features a wide-to-normal range, allowing for a lighter kit bag, thereby compromising on image quality. The Sigma 17-40mm f/1.8 DC Art lens is also set to feature a total of 17 elements in 11 groups, with four aspherical and four Special Low Dispersion elements to minimize flare and ghosting and suppress various aberrations. Overall, this should result in an optical performance that meets or exceeds that of other Sigma Art lenses, including the 18-35mm f/1.8 DC HSM Art lens. Along with its 11-blade, rounded diaphragm, the design promotes sharpness and a large, smooth bokeh when used wide open. In addition to the f/1.8 maximum aperture, the lens also maintains an 11" minimum focusing distance across the entire zoom range. It achieves a maximum magnification ratio of 1:4.8 at its longest focal length, increasing depth of field and versatility in tight spaces.Video-Friendly FunctionalityWhat’s cool about this new Sigma 17-40mm f/1.8 DC Art lens is that it’s certainly been designed with video production in mind, as the lens' bright f/1.8 aperture and wide-to-normal zoom range make it a versatile tool ideal for single-shooter, run-and-gun setups.An internal zoom design maintains the overall length during use, making it easy to balance on gimbals.
