Sigma 105mm f/1.4 DG HSM Art

Sigma’s reputation for high-quality lenses continues to grow, thanks to the Art series. These photo lenses offer incredible but affordable quality, and lend their optical design to Sigma’s full-frame cinema lenses.

Art is viable for Canon, Sony and Sony mount cameras. This 105mm f/1.4 is the longest in the range and, says Sigma, the master of bokeh and perfect for portraits, as the extra focal length gives a little more compression to bring the background closer. On an APS-C or Super35-size camera it’s roughly equal to a 160mm lens, but with an enviable f/1.4 maximum aperture.

Sigma’s premium lenses often out-perform manufacturers’ own glass and the new 105mm really delivers. Seventeen optical elements in 12 groups is a huge amount for a prime lens. With five special low-dispersion elements and one aspherical lens element, plus a rounded nine-bladed diaphragm for smooth out-of-focus areas,  it’s no lightweight in performance, or in actual weight. Housed in a sturdy metal body (1645g and 131.5mm long) it is heavy and big for a 105mm lens, especially with the detachable mammoth lens hood. The tripod mount is a useful addition.

Images are sharp and detailed, with attractive and smooth out-of-focus areas, aided by the longer focal length. We used a Canon-mount version on a Canon DSLR and on a Sony A7R III with a Metabones adapter. On the Canon the lens worked as well as a native lens with the Dual Pixel AF system. On the Canon and Sony we also used manual focus; perfect every time thanks to focus confirmation.
