A versatile zoom for everyday shooting, the Canon EF-mount Sigma 24-70mm f/2.8 DG OS HSM Art Lens Canon EFfrom Sigma 24-70mm f/2.8 DG OS HSM Art Lens Canon EFcovers a useful wide-angle to portrait-length range of focal lengths to suit shooting in a variety of environments. As part of the esteemed Art series of lenses, a sophisticated optical design is used that incorporates three SLD elements and four aspherical elements to reduce chromatic and spherical aberrations, as well as color fringing, distortions, and other anomalies for greater clarity and sharpness. A Super Multi-Layer Coating has also been applied to suppress lens flare and ghosting for accurate color fidelity and high contrast, and a protective coating has been applied to the front element, too, to benefit working in harsh climates. Additionally, extending its versatility, a constant f/2.8 maximum aperture affords consistent performance throughout the zoom range as well as greater control over depth of field.

Complementing the imaging capabilities, the lens sports a Hyper Sonic Motor to produce quick, smooth, and quiet autofocus performance with full-time manual focus override. An Optical Stabilizer also benefits handheld shooting by minimizing the appearance of camera shake for sharper imagery. The physical design utilizes Thermally Stable Composite material for durability in a wide range of environments, and a brass bayonet mount also offers rigidity and mounting precision.

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.

Standard zoom lens is designed for full-frame Canon EF-mount cameras, however it can also be used with APS-C models where it will provide a 38.4-112mm equivalent focal length range.

Constant f/2.8 maximum aperture is well-suited for working in available light conditions and also provides greater control over depth of field when using shallow depth of field techniques.

Three Special Low Dispersion (SLD) elements markedly reduce chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy.

Four aspherical elements control spherical aberrations and distortion for increased 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) 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.

Optical Stabilizer system minimizes the appearance of camera shake by up to four stops to benefit making sharper imagery when shooting handheld.

Rounded nine-blade diaphragm is constructed from durable, fluorine-coated polycarbonate and also features a carbon feather film for smooth performance when working with fast continuous shooting rates.

Front lens element has been treated with a water- and oil-repellent coating to benefit working in harsh environmental conditions.

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. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.

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. Will this be released in the Sony EF mount in the future?

A: Lol.

Q: 2. Does its aperture change when zooming ?

A: Just to be more clear. A lens which says: 2.8 or 4. keeps the same aperture all the way from wide to tele. A lens that say: 3.5-5.6 with be 3.5 at wide and 5.6 at tele. To find exactly where, test by shooting 5-6 shots at different points on the zoom and look at the properties of the JPEG or where ever it will say the zoom and aperture.

Q: 3. What is its weight?

A: Always read the specs on the B&H site where the lens is sold... It is all there. Save your time asking others who might be wrong.And, go to the company site and see for yourself.

Q: 4. You say it's coming out in June but it's Aug. What's the hold up ?

A: I'm wondering the same thing. I ordered it immediately when the preorder email was sent out over a month ago. Seems like some people got the canon version and wrote reviews. Did you get any of the Nikon version in stock to send out? There are no customer reviews for the Nikon version so I assume not? When do you expect some to be sent out? I know it's first come/served but it would still be nice to have an idea.

Q: 5. Is this full frame ?

A: Yes, the Sigma 24-70mm f/2.8 DG OS HSM is full-frame compatible.

Q: 6. Is their any locking mechanism for the zoom? If not, is the zoom mechanism firm enough to not slip when carrying the camera on a sling ?

A: No locking mechanism I could find.It's firm enough to keep it in the zoom distance you set. That said, with the lens bouncing on a sling something else on your body might make it spin and change the desired zoom level. It's smooth transitioning which makes it not bump safe from my experience.

Q: 7. How will this lens work with a crop sensor Nikon D7200?

A: Any Nikon F mount lens on a D7200 crops 1.5 times. So, a 24-70 lens like the Sigma 24-70mm f/2.8 DG OS HSM Art Lens for Nikon F on a D7200 is like a 36-105mm lens.

Q: 8. How does this compare to the Canon 24-70 2.8 II?

A: I've owned this lens for 2 months. Its amazing. Built like tank, and operates with buttery smooth precision. Weather and dust resistant too. I borrowed a canon 24-70 II for a shoot before purchase. Also a great lens, .5 lbs lighter, but no IS. I haven't noticed a difference IQ wise. The background blur is beautiful. Focus is fast and extremely quiet. I chose this lens because it has IS and I wanted to have the flexibility to take off tripod video of moving objects. It has not disappointed me, and was $500 less than the Canon equivalent. I picked up a refurbished 85 prime, extra battery and SD card with the money I saved. I have no regret purchasing this lens. Its a spectacular performer.

Q: 9. this lens has any type of tripod mount? i plan to use it on a monopod for video shooting on a sony body via de mc11 adapter. Do you guys think the lens mount on the camera will suffer the heavy weight of this lens?

A: No mount on the lens it's self for a tripod. Maybe a third party lens collar might be a solution.

Q: 10. Is this Sigma 24-70 f2.8 lens compatible with the Canon C100ii body? How is the image stabilization feature? Works well?

A: The Sigma 24-70mm f/2.8 DG OS HSM Art Lens for Canon EF is compatible with the Canon EOS C100 Mark II Cinema EOS Camera. The Image Stabilization on this lens is very good.
