![]() ![]() The lens comes in Canon, Nikon, Pentax, Sigma and Sony versions our review sample was in the Canon EF mount. It's still pretty quiet, but if you refocus during movie recording, the clicking of the AF motor as it fine-tunes focus might be audible on your soundtrack in quieter conditions. Focusing slows down considerably, although the exact speed will be highly dependent on the camera used. Switch from the optical viewfinder to live view, though, and the storyĬhanges. As always, though, it must be noted that focus speed and accuracy is dependent upon a number of variables, including the camera body used, subject contrast, and light levels. We've seen no evidence for systematic focus errors on test bodies ranging form the entry-level EOS 650D to the top-of-the-line EOS-1Ds Mark III, either. For normal eye-level shooting we've found our Canon-mount copy to perform very well, offering fast, silent and positive focusing. The 35mm uses Sigma's Hypersonic Motor for autofocus. But with a normal grip supporting the lens with your left hand, this really isn't a problem. SLRs like the Canon EOS 650D shown right, the overall balance shifts much more towards the lens itself. Despite this it balances well on larger SLRs, and is perhaps most at home on mid-size full frame bodies such as the Canon EOS 5D Mark III, Nikon D800 or Sony SLT-A99. The Sigma is a fairly chunky optic, indeed it's the heaviest and physically longest of all autofocus 35mm F1.4s. All offer minimum apertures of F16 or F22, and minimum focus distances of about 0.3m.Ĭlick here for a more-detailed specification comparison between these lenses On the camera The table below compares the Sigma's key specifications to its main competitors. Key specifications compared to other 35mm F1.4 SLR lenses One possible concern, depending on your needs, is that the lens isn't weathersealed (unlike its Nikon counterpart). The lens looks attractive too, which is utterly non-essential but still always a bonus. There's really nothing to complain about here in terms of fit and finish either, which feels superb. These thoughtful little touches help make the lens a pleasure to use. The auto/manual focus mode switch on the side of the barrel is unusually generously-sized, and a large area of the barrel's underside is ridged to provide a positive grip when changing lenses. The broad manual focus ring occupies the front of the barrel, and turns smoothly - it doesn't rotate during autofocus, which is always welcome. A small inlaid silver plaque with the letter 'A' denotes that it's part of Sigma's new 'Art' line. ![]() Cosmetically it's unlike any of the company's previous optics, with an all-metal barrel that uses mainly a matte finish, but with a more-glossy section next to the mount. The 35mm F1.4 DG HSM marks a new direction for Sigma in terms of design and build quality. ![]()
