![]() There's a big manual focus ring with a ridged, rubberized grip, and a toggle switch to change between autofocus and manual focus operation. ![]() There's no optical stabilization-that's not something you often see outside of zoom lenses and telephoto primes-but Sony shooters can benefit from the in-camera stabilization that Alpha SLRs provide. It's eligible for the company's mount conversion service, and its autofocus performance can be tweaked using an optional USB Dock ($42.00 at Amazon). The lens is available for Canon EF, Nikon F, Leica/Panasonic/Sigma L, Sigma SA, Sony A, and Sony E cameras. Utilizing the included petal-style reversible lens extends the height of the lens to about 6.0 inches. It measures 3.9 by 3.4 inches (HD), weighs 1.9 pounds, and uses big 77mm front filters. Make no mistake, the 50mm F1.4 ($699.95 at Amazon) is on the large side for a standard-angle prime lens. Like its wider sibling, the Sigma 35mm F1.4 DG HSM Art ($642.78 at Amazon), it earns high marks and our Editors' Choice award. It outperforms the Nikkor 50mm f/1.4G at wider apertures, and while it's not an example of pure optical perfection like the Zeiss Otus, it's not that far off and it's a quarter of the price. Now that we've gotten our hands on a production sample and put it through its paces, it's clear that the new lens is a huge step forward from the older Sigma optic. Sigma's older 50mm F1.4 EX DC HSM was a good lens, but it lagged behind the Nikon AF-S Nikkor 50mm f/1.4G ($406.95 at Amazon) in sharpness, especially at the edges of the frame. ![]() ![]() Sigma turned more than a few heads when it hinted its 50mm F1.4 DG HSM Art ($949) lens was poised to perform in the same league as the Zeiss Otus 55/1,4.
