I do not have a test bench at home to do tests, and anyway, it is useless since the most reliable and serious ones are already online for a long time. You may also like - Sigma 45mm F/2.8 DG DN Contemporary Lens Review And the Optical Quality? It is rarely a problem at these focal lengths, especially since a huge aperture allows you to gain shutter speed more easily. Sigma also does not offer a stabilization system. What does that mean to you? Well, you will not have a small telephoto lens, which means that you will have to avoid making tight portraits at the risk of distorting the face of your models by getting too close. You will have noticed, while the standard zooms usually propose to go from 17 to 50 or 55 mm, this one stops at 35 mm. You guessed it the optical engineers are not magicians (although here they amaze me!), compromises had to be made to propose this approach.įirst of all, the lens is reserved for APS-C sensor SLRs, which remains the majority of the market. Sigma 18-35 mm f/1.8 Art What Compromises? 😉 By offering us no more or less than a zoom opening at f/1.8: The Sigma 18-35mm f/1.8 DC HSM Art. They have the disadvantage of being less flexible since one cannot quickly adapt to a change by zooming or de-zooming.Īnd here, Sigma throws a rock into the pond (the pad was too small. We often prefer these for the portrait because they allow a much smaller depth of field. However, at f/2.8, we still do not reach what fixed focal lengths can do, which open at f/1.8 or higher. In short, it’s all technically and artistically beneficial. A large maximum aperture allows both to work more simply in low light and more possibilities in terms of depth of field. Usually, large aperture zooms are limited to f/2.8, and honestly, it’s already quite a bit. A Small RevolutionĪnd it’s a small revolution. Indeed, Sigma released in 2013 the first zoom in the world whose maximum aperture is f/1.8 at all focal lengths (which does not mean that you cannot close the diaphragm.
If you know the importance I attach to a large maximum aperture, you may reasonably suspect that I rushed into the opportunity to try the world’s first f/1.8 zoom. It would not be very relevant, in my opinion, to try a lens that does not easily fit into your current photo practice.
For this review, I select the “Sigma 18-35mm f/1.8 Art Lens”. When I do lens tests and reviews, they can often interest me personally for a purchase.
