Sigma 24-35 mm f / 2 DG HSM Art

Sigma announced the new Sigma 24-35 mm lens f/ 2 DG HSM Art, for 24×36 mm format, the first of its kind with brightness and focus range.

The Sigma 24-35 mm f / 2 DG HSM Art is indeed the only angle zoom f/2 lens line that follows an optical schematic of 13 groups from 18 lenses, seven of which are made of SLD optical glass of super-low chromatic dispersion, two of them non-spherical, while a lens uses the famous FLD optical glass invented by Sigma, as its features are equivalent to fluorite glass, but without the drawbacks. As for the non-spherical lenses, some of them are of a particularly large diameter, which required special production techniques.

The idea of Sigma engineers was to create a zoom lens whose optical quality was the same of the best fixed focal lenses, which covers -24 mm, 28 mm and 35 mm, a zoom that contravenes the concept of commitment associated with that type of optical lenses.

Thus, apparently this concept has minimized spherical aberration, axial chromatic aberration and field curvature. According to the designers, they have taken maximum measures from the first steps of the process to prevent flare due to stray light through Multi-coating, combined with the curvature calculation of the lens.

While other angle zoom lenses only open to f /4 or f/3.5, it’s not easy to create selective focus, as opening up to f/2 results in a considerable difference, and so the Sigma 24-35 mm f/2 DG HSM Art incorporates a nine-blade diaphragm, in order to provide a harmonious bokeh from f/2.8. With all the more reason and to maintain diffraction under the greatest control, the diaphragm closes only to f/16.

The barrel is made of composite TSC, which offers similar features to metal (aluminum) in regards to durability and expansion thermal index, with the saddle brass having a surface treatment that makes it more durable and with less friction.

Sigma introduced some silent product improvements. So now the umbrellas have incorporated joints in the lens’ connecting parts, while the AF / MF switches have been redesigned for greater ease of use and even the covers had some minor changes done.

The photographers that buy this optical will know well which the ideal application fields are, but Sigma reminds us that among them there may be portraits of people in their environment, landscapes, architecture, interiors with low lighting, street photography, etc, all without forgetting the most important advantage of a zoom lens: there’s no need to change lenses to change focal, as well as the possible frame micro adjustments between one focal and another.

This lens, calculated to cover three of the most demanded angular focal by professionals and enthusiasts alike: -24 mm, 28 mm and 35 mm, it incorporates a nine blade diaphragm for a harmonious bokeh and its focus is up to 28 cm, with great smoothness, speed wide angles and precision thanks to its Hypersonic focus engine (HSM).

It does work down to a minimum focusing distance of 28 cm, which offers a maximum reproduction ratio of 1: 1.44. The focus is internal, so the lens does not change its physical dimensions, and it doesn’t have to rotate the front lens, which facilitates use with polarizers and video accessories.

The Art line to which the new Sigma 24-35 mm f / 2 DG HSM belongs is one of the highest performance and brightness of the brand, and its lenses can be customized through the Sigma USB Dock, and even if necessary, you can change the mount –in workshop, of course- between Sigma, Canon and Nikon, the mounts for which it is marketed at this time.

The physical parameters are Ø 87.6 mm x 122.7 mm for 940 grams, with filter thread of Ø 82 mm. The price has not been set so far, but we would dare to think that, according to the brand’s history, number of lenses and other aspects, it could be costing around 1,200 €.

At this moment, the Sigma Art line includes models such as:

24×36 mm format (DG)
Sigma 24 mm f/1,4 DG HSM Art
Sigma 35 mm f/1,4 DG HSM Art
Sigma 50 mm f/1,4 DG HSM Art
Sigma 24-35 mm f/2 DG HSM Art
Sigma 24-105 mm f/4 DG OS HSM Art

And the lesser known something:
APS-C (DC) Format

Sigma 30 mm f/1,4 DC HSM Art
Sigma 18-35 mm f/1,8 DC HSM Art
Montura Micro Cuatro Tercios y Sony E/APS-C (DN)
Sigma 19 mm f/2,8 DN Art
Sigma 30 mm f/2,8 DN Art
Sigma 60 mm f/2,8 DN Art

    I have the Sigma 18-300mm using it on the Canon 60d.

    It’s not the best performer but for the price it was Un beatable.

    It performs below average in low light even at f3.5 18 mm and is not very good at night shots either. The focus can be soft at best of times and macro shots are ok.

    If I were to purchase a Sigma product again I would definitely lean towards the art series
