Best 50mm lens for your camera: Sigma 50mm f/1.4 EX DG HSM
You can expect f/1.4 lenses to be bigger and heavier than their f/1.8 counterparts, but the Sigma really does go large in its design.
At 505g, it’s about twice the weight of some f/1.4 lenses on test, and up to four times the weight of the f/1.8 lenses.
Meanwhile, its extra girth is reflected in its oversized 77mm filter thread, where most other 50mm f/1.4 lenses have a 58mm thread (55mm for the Sony).
Extra weight isn’t necessarily bad news, however: the Sigma feels well balanced when shooting on big, full-frame cameras.
As with the Nikon lenses here, autofocus is courtesy of a fast and whisper-quiet ultrasonic ring-type system. It’s accurate, and full-time manual override is silky smooth, with a well-positioned and high-precision focus ring.
Build quality feels tough and dependable, although there are no weather seals fitted to the lens. In common with only the Nikon 50mm f/1.4 lens group, the Sigma features nine diaphragm blades, where most others have only seven.
This helps to maintain a well-rounded aperture, from wide to medium settings. A petal-shaped lens hood and carrying pouch are supplied with the lens, both of which are of good quality.
A bonus of the Sigma’s large front element is that vignetting is fairly minimal, even when shooting at f/1.4 on a full-frame body. Bokeh is smooth and pleasant, but the lens is a bit of an under-achiever when it comes to image sharpness at wide apertures.
