Sigma 50mm F1.4 DG HSM review

The Sigma 50mm F1.4 DG HSM | Art is a fast ‘normal’ lens designed for full frame SLRs, and one of the about hotly-anticipated lenses of 2014. Sigma shook upward the moribund ‘fast l’ sector dorsum in March 2008 when it announced the 50mm F1.four EX DG HSM, which we considered to exist ‘Highly Recommended’ for its impressive optics, especially at larger apertures. This marked the start of string of excellent fast primes from the Japanese lens maker, including last yr’s stellar 35mm F1.4 DG HSM | Art (another winner of our peak laurels).

The latest 50mm is unusually large and expensive for its type; indeed its $950 / £850 / €1000 price tag suggests Sigma is aiming at users who might otherwise choose the Nikon AF-S Nikkor 58mm F1.4G, Canon EF 50mm F1.2L USM, or Sony Carl Zeiss Planar T* 50mm F1.four ZA SSM. It bears a distinct family unit resemblance to the company’s 35mm F1.4, but if anything is slightly larger, with a 100mm / 4″ long butt and 77mm filter thread. Its complex optical formula of 13 elements in 8 groups isn’t based on a conventional double-Gauss blueprint, like near 50mm primes are, but instead is of the retrofocal type.

This ready of characteristics, along with Sigma’due south recent track record of making impressive optics, means that the 50mm F1.4 Art has inevitably invited comparing to the astounding Zeiss Otus one.4/55 – quite possibly the sharpest lens nosotros’ve still seen. Even so, given that lens’due south $4000 price tag, information technology seems a little optimistic to look quite the same qualities. But the Sigma offers autofocus
via
a ring-type ultrasonic motor (with full-time manual override), which ways information technology wins out on practicality. The new lens’s premium price point likewise ways that it doesn’t directly supercede the older model, which we understand will continue to be sold for some time notwithstanding.

Headline features

  • 50mm focal length
  • Fast F1.4 maximum aperture
  • Ring-type ultrasonic autofocus motor with full-time manual override
  • Internal focus design
  • Will be available in Catechism EF, Nikon F, Sony Alpha, and Sigma SA mounts

Angle of view

The pictures below illustrate the 50mm F1.four Art’s angle of view on full frame and APS-C, taken from our standard position. As is Sigma’s mode, the lens is simply slightly ‘wide’ for a 50mm prime (its measured focal length is 48mm), bringing information technology closer to a classic ‘normal’ view on full frame. On APS-C cameras information technology behaves like a brusque telephoto lens.

Total frame 1.6x APS-C
(~80mm equivalent)
