Sigma announced 18-35mm F1.8 DC HSM Art Lens

April 18, 2013

Sigma has announced the 18-35mm F1.8 DC HSM Art lens. This is the World’s first constant F1.8 zoom lens that was designed for APS-C DSLR cameras.  On a 1.5x crop sensor this lens is equivalent to 27-52.5mm. This lens joins the other five ‘Art’ lenses, among those are the 35mm F1.4 DG HSM, 30mm F1.4 DC HSM and three DN Lenses for mirrorless Interchangeable lens cameras.

The Sigma 18-35mm f/1.8 DC HSM Art lens utilizes 5 SLD glass (Special Low Dispersion) elements and four GLASSMOLD Aspherical lenses. Sigma work hard to finalize this lens to meet the highest standards, reducing optical aberrations and designing this lens to meet the demands of enthusiasts and professional photographers. As for the time of writing this article Sigma hasn’t said for which camrea mounts this lens would be available, but according to their product page where they mentioned the 46-megapixel Foveon direct image sensor, I assume that it will be available Sigma SA mount among the others and will be compatible with Sigma’s Foven-based DSLR cameras, the SD1, SD15 and older models.

So who will benefit of such lens? – Wedding photographers,  Indoor events, landscapes, portraits, still-life, close-up and even great for videos as well. The thing is that most professional photographers don’t use a crop sensor DSLR, at least not as their main camera. Some professional cameras do have a crop mode where they can use such a lens with smaller projected image circle, but this will result in an image will a lower resolution. I’m pretty sure that this lens will find itself in the bag of many enthusiast photographers who just dreamed of such a lens. It’s only 2x zoom, but for some people it might replace two or more prime lenses, and can save quite a lot of money for some.

The Sigma 18-35 mm F/1.8 DC HSM Art lens utilizes Super Multi-Layer Coating to reduce flar and ghosting and help result in higher contrast and sharp images. The lens comes with a lens hood (LH780-06) that also helps minimize flare and ghosting.  The lens doesn’t come with internal lens-shift image stabilization, but for that relatively wide angle and this fast aperture is not necessary — your stabilizer is your aperture, more light means that you can shoot at faster shutter speeds.

This lens accepts filter such as Circular Polariser due to a non-rotating front part. It utilizes Hyper Sonic Motor for fast and silent autofocusing and has a manual smooth focusing ring that allows you to further adjust your focus if you need to.

The 18-35mm F1.9 DC HSM Art lens also support the “USB DOCK” which allows you to attach the lens to it and update the lens firmware using the “Sigma Optimization Pro” software.

All in all, I have high expectations from this lens. Price and mount availability were yet to be announced.
