Sigma’s Art lens lineup continues to impress with the introduction of the 24-35mm f/2; the world’s fastest constant aperture full frame zoom lens.
The focal length struck some people as odd, others were disappointed it wasn’t the rumored 24-70mm f/2 lens, but if this lens is as good as Sigma says it is it could easily replace 24mm, 28mm and 35mm prime lenses for those who do not need the f/1.4 aperture.
The company calls this lens “another notch on Sigma’s belt for pure photographic innovation”, and I couldn’t agree more.
In order to build the should-be fantastic lens, Sigma included premium FLD (“F” Low Dispersion) glass, which is said to be equal in performance to fluorite, and seven SLD (Special Low Dispersion) glass elements.
A large diameter aspherical lens is also incorporated for extra brightness and an improved AF algorithm, together with the Hyper Sonic Motor (HSM) should enable the focusing to be as good as the optics.
The lens is built of 18 elements in 13 groups, 9 rounded diaphragm blades and has a minimum aperture of f/16.
Minimum focusing distance for the new zoom is 28cm (11”) with a maximum magnification of 1:4.4 and a filter size of 82mm.
As you’d expect of an Art lens, this one is also built to last and the 940g (33.2oz) weight means it will feel solid as well.
The lens will be available in Sigma, Nikon and Canon mounts, but there’s still no word on pricing or availability.
