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.

I have the Sigma 18-300mm using it on the Canon 60d. It's not the best performer…

Sigma goes out on a limb, considering the development of a Foveon full-frame sensor

The folks at Imaging Resource have interviewed Kazuto Yamaki, executive president of Sigma. And the truth is that he’s dropped a few interesting pearls that let us intuit where the company–one of the main manufacturers of multiplatform lenses on the market–is going.

Though Yamaki affirms that he can’t foresee information about the products Sigma will launch in the future, he acknowledges that many users have asked him to work on a camera similar to its de Quattro but equipped with a Foveon full-frame sensor. And, in the face of all this demand, he’s said that Sigma’s seriously considering this idea.

According to Yamaki, applying the architecture of the Foveon sensors that, as you all know, lack the Bayer color matrix used by conventional sensors, to a 35-mm sensor poses big challenges. Without a doubt, this is very good news, above all after finding out how good the 4th-generation Foveon sensor in a dp1 Quattro looks on paper.

Is Sigma planning to launch lenses for Fujifilm’s X Series?

Even though the quality of Fujinon’s lenses is superb, many of us would like to see other companies seriously consider the X Series a system to work on and make more affordable lenses available. Though we’ve already seen interesting manual lenses from other companies like Samyang, the best news would be to see the two main "third parties" for reflex cameras, Tamron and Sigma, stepping into the Fujifilm universe.


We learned through Fujirumors of a video interview of Kazuto Yamaki, CEO of Sigma, conducted by the Italian website fotografia.it. In the fifty-minute long interview, Yamaki discussed his production philosophy, technological advances in optical manufacturing, and future product launches of lenses. On this last point he let slip that, despite centering his production line on objectives for reflex cameras, he has a great interest in mirrorless cameras, even though the development of new lenses would require lots of time and despite the limited resources his company has available. For that reason he’s expressed the importance of demarcating his target audience: the amateur photograph with experience who needs a mid-range product. With all surety, Fujifilm’s X Series could fit very nicely in the Japanese company’s expansion plans, now that the horde of Fujifilm photographers is much more visible.

Sigma warns that some of their lenses might cause conflict with the Nikon Df

A few days ago, Sigma announced that some of their lenses may be incompatible with the Nikon D5300, and now they’ve said the same about the Df. The Japanese company announced that their lenses may experience incompatibility issues with the new Nikon Df as well.


Both lenses with internal focus engine and those without it are affected by this. Just how it happened with the D5300, you can fix this by getting the most recent firmware update.

Also, the lenses that already come with this issue solved by default will by identified by stickers that indicate the compatibility with the Nikon D5300, the Df or both.

Sigma warns about the compatibility issues of some of their lenses with the Nikon D5300

The company today launched a firmware update to fix this problem.

Neither the contrast-based focus system nor the Live View mode or optical stabilizer of Sigma’s lenses work correctly when used with the Nikon D5300. The Japanese company has not specified if this is a widespread problem or if it only affects certain lenses.

In any case, Sigma has already promised a firmware update that will be available today and promises to correct these errors. For discontinued lenses, the users will have to contact the company, although they have warned that in some cases they won’t be able to fix this problem.
