Distinguished by a uniquely fast and versatile design, the Canon EF-mount Sigma 18-35mm f/1.8 DC HSM Art Lens Canon EFis an Art-series zoom, covering wide-angle to normal focal lengths. Separating itself from the pack, this zoom features an exceedingly bright f/1.8 constant maximum aperture, which suits its use in difficult lighting conditions and offers impressive depth of field control throughout the zoom range. The optical design incorporates a series of SLD and aspherical elements, which help to achieve high clarity and sharpness by suppressing various aberrations, color fringing, and distortion. A Super Multi-Layer Coating has also been applied, too, which controls lens flare and ghosting for improved contrast and color accuracy. Balancing the optical merits, this 18-35mm also sports an advanced Hyper Sonic Motor, along with an internal focusing design, to promote fast, quiet, and precise autofocus performance.

As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.

Wide-to-normal zoom is designed for APS-C-format Canon EF-mount cameras and provides a 28.8-56mm equivalent focal length range.

Impressively bright constant f/1.8 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques.

Five Special Low Dispersion (SLD) elements are featured in the optical design and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy.

Four aspherical elements are used to help limit distortion and spherical aberrations and also contribute to greater overall sharpness and accurate rendering.

A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.

Integrated HSM (Hyper Sonic Motor), along with an internal focusing system, realizes quick and quiet autofocus, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time.

Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.

Constructed using a Thermally Stable Composite (TSC) material for greater precision and use in wide temperature variations. Additionally, a brass bayonet affords improved mounting accuracy and rigidity.

This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.

Related Questions and Answers

Q: 1. What if you don't want shallow depth of field but rather increased long depth of field as in a landscape?

A: use a higher f-stop number

Q: 2. Is this lens compatible with the Nikon D500 body? I'm confused by the F or G mount.

A: G is not a mount name. All Nikons have the same mount to a Nikon camera. Look for Nikon F... G is just a lens model type.

Q: 3. Will this work with Nikon D7000?

A: Yes, this lens is fully compatible with the Nikon D7000 camera.

Q: 4. will this lens work with a canon 50d?

A: It worked perfectly on my 70D which has a very nice AF system. Not sure how fast the AF will be on a 50D but should work fine.

Q: 5. Does this lens have vingetting if you use it on a gh5 with a metabones speedbooster ultra? It says the lens is designed for cameras with a 1.5x crop but the speedbooster ultra allows the gh5 to have a 1.42x crop. I am worried that the lens would not cover the entire sensor

A: It works great! Gh5 will ask you to set the focal length for the lense attached when you turn it on. Or you can hold down the button on the speedbooster while turning on the gh5 to bring up the settings. Multiple .71 by the max focal length (35 on the sigma art) to get the right focal length setting. No vingetting!!

Q: 6. Will this work on a Canon 70D ?

A: Yes, this lens is fully compatible with the Canon EOS 70D.

Q: 7. How weatherproof is the lens?

A: The only Sigma lenses that are weather sealed are their Sport lenses. If you plan on shooting in adverse conditions with the Sigma 18-35mm f/1.8, using protective gear such as a rain cover would be prudent.

Q: 8. Do you ship to Guam?
