The new Sigma Art AF 12-24/4.0 DG HSM is a worthy successor to Sigma's AF 12-24mm 4.5-5.6 II DG HSM model from 2011. Optical performance is very good and other aspects of the lens are also improved: The focal ratio is now a constant f4.0, AF is faster, and you get compatibility with Sigma's USB dock to fine tune various characteristics of AF…

The Sigma 85mm f1.5 Art is a short telephoto prime lens designed for full-frame bodies and available in Canon EF, Nikon and Sigma mounts. It's a highly anticipated update to the previous 85mm f1.4 from Sigma and anyone following the Art series won't be disappointed as Thomas declares it the best 85mm f1.4 with autofocus he's tested!

The Sigma 24-35mm f2.0 DG HSM Art is a one-of-a-kind lens: It simply is the largest aperture full-frame zoom lens around and it also delivers very good image quality. As such the new zoom is a very compelling addition to Sigma's catalogue. Add Sigma's build-quality of the "Art" series and the option to swap the lens-mount should you change…

The Sigma 20mm f1.4 DG HSM Art is a one-of-a-kind lens: It simply is the widest full-frame f1.4 lens around and it also delivers very good image quality. As such the new Sigma is a very compelling addition to the catalogue of large aperture wide-angle lenses. Add Sigma's build-quality of the "Art" series and the option to swap the…

The Sigma 24mm f1.4 DG HSM Art is a very compelling addition to large aperture wide-angle lenses: it combines very good performance overall with Sigma's build-quality of the "Art" series.
In optical performance this lens has only two flaws: It has some field curvature and a dip in resolution at the DX-corner but that does not prevent the lens from…

Sigma's 50mm f1.4 ART is a high-end standard lens for Canon, Nikon or Sony mounts. Superb quality makes it the best 50mm with AF I've tested.

The 24-105mm f4 OS is Sigma's second full-frame lens in its Art-series which (quote Sigma) "offers sophisticated optical performance and abundant expressive power to deliver faithfully on your artistic vision". Blimey.
The first full-frame Art lens was the 35mm f1.4 DG HSM which put in some astonishing performance in the corners of the full-frame sensor (see my Sigma 35mm f1.4 review).…

The 35mm f/1.4 DG HSM is Sigma's first large aperture 35mm full-frame lens. It was announced November 2012 and goes head-to-head against the equivalent offerings from Nikon, Canon and Sony.
As Sigma's first lens to define its "Art" product line (the others being "Contemporary" and "Sports") it is expected to "focus on sophisticated optical performance and abundant expressive power". It is…

If you're shopping for a bright aperture telephoto prime lens for a Nikon DSLR, you'll no doubt be weighing up the pros and cons of all three models. But which really is best? Does newer equal…
