Pairing a versatile range of wide-angle focal lengths with an impressively bright design, the Sigma SA-mount Sigma 14-24mm f/2.8 DG HSM is an Art-series zoom, distinguished by its fast f/2.8 constant maximum aperture to suit working in available lighting conditions. Featuring a sophisticated optical design, this lens utilizes a series of low dispersion and aspherical elements to minimize both chromatic and spherical aberrations throughout the zoom range in order to achieve high sharpness, clarity, and color accuracy. A Super Multi-Layer Coating also helps to suppress lens flare and ghosting for color-accurate, contrast-rich imagery in a variety of lighting conditions.

Benefitting handling, this 14-24mm is equipped with a Hyper Sonic AF motor with an optimized algorithm for speed and accuracy. The lens also offers a large focusing ring with full-time manual override settings for quickly making adjustments. A rounded 9-blade diaphragm improves image quality by helping create smooth bokeh, and the lens is constructed from a lightweight and durable thermally-stable composite. Additionally, a built-in lens hood helps to protect the front element as well as prevent stray light from causing flare.

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-angle zoom is designed for Sigma SA-mount cameras, and when used with an APS-C model, it provides a 21-36mm 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.

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

Three 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.

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

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.

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 lens fit onto a Canon EOS 70D Camera? If I need a a lens adapter how can I find the appropriate mount?

A: Yes, its fully compatible with the 70D. Even though it is a full frame lens, it will work well on the 70D.

Q: 2. Is this a parfocal lens? Also, does the lens breathe or expand/contract when zooming?

A: It is not parfocal. There are reports of minor focus breathing at 14mm and 24mm.

Q: 3. what are the options for using a filter if there are no filter threads?

A: Or you can use a traditional matte box to hold filters and shade the lens.

Q: 4. Will this cap fit the Sigma 15-30mm 1:3.5 - 4.5?

A: Since your lens is no longer made, I see why you are considering this cap since we do not have a replacement cap and I think unlikely that Sigma does as well. So some fudging is in order. The Sigma Lens Cap for 14-24mm f/2.8 DG HSM Art Lens B&H # SILC96401 is meant to fit on the Sigma 14-24mm f/2.8 DG HSM Art Lens. This lens has a 3.8 diameter. The no-longer-available Sigma Zoom Super Wide Angle 15-30mm f/3.5-4.5 EX Aspherical DG DF Autofocus Lens for Pentax AF B&H # SI153035PAF has a maximum diameter of 3.4 . I would order the cap and some Velcro. Apply the soft side of the Velcro to the inside of the cap to make up for the size difference. You may have to also apply it to the diameter of the lens. Velcro VEL-90209 Set of 4 Touch-fastener Strips (Black) B&H # VEVEL90209. Good luck.

Q: 5. Is this Lens weather sealed?

A: Yes, this lens is weather sealed.

Q: 6. Will this lens work with a Canon R6 with the adapter?

A: Yes this lens is compatible with the Canon EOS R6 when using one of the Canon EF-R Lens Adapters.

Q: 7. How does this lens handle distortion? I like to go close to the talent with the Ursa Mini Pro?

A: This is a high quality lens that should show little distortion. However when getting close ups you may want to be set at 16mm or 18mm to avoid it warping too much on their faces.

Q: 8. Can you attach circular ND filter?

A: This lens does not have front filter threads. You can attach a large filter holder like this one to the front BH #FOWP186CORSM and on the filter holder you can use a round 186mm filter like this one: B&H # FOWNDP186ND8

Q: 9. The stated angle of view is 114.2° to 84.1° . Is that horizontal or diagonal angle of view?

A: Diagonal.

Q: 10. How well does this lens perform during astrophotography?

A: I have found this to be a fantastic lens for astrophotography. I used it to photograph the Milky Way and Perseid meteor shower with great results.
