Sigma 40mm f/1.4 DG HSM Art Lens for Canon EF
Key Features
  • EF-Mount Lens/Full-Frame Format
  • Aperture Range: f/1.4 to f/16
  • Three FLD Elements, Three SLD Elements
  • One Aspherical Element
Designed within the rigorous tolerances of a cine lens, the Canon EF-mount Sigma 40mm f/1.4 DG HSM Art Lens is a wide normal-length lens characterized by a bright design and sophisticated optical layout. The fast f/1.4 maximum aperture helps to achieve shallow depth of field and selective focus effects, and also suits working in difficult lighting conditions. The optical design incorporates a series of low dispersion and aspherical elements, which help to improve sharpness and clarity by controlling both spherical and chromatic aberrations. A Super Multi-Layer Coating is also featured, and helps to minimize flare and ghosting for greater contrast and color accuracy when working in strong lighting conditions.

Sigma 40mm f/1.4 DG HSM Art Overview

Designed within the rigorous tolerances of a cine lens, the Canon EF-mount Sigma 40mm f/1.4 DG HSM Art Lens is a wide normal-length lens characterized by a bright design and sophisticated optical layout. The fast f/1.4 maximum aperture helps to achieve shallow depth of field and selective focus effects, and also suits working in difficult lighting conditions. The optical design incorporates a series of low dispersion and aspherical elements, which help to improve sharpness and clarity by controlling both spherical and chromatic aberrations. A Super Multi-Layer Coating is also featured, and helps to minimize flare and ghosting for greater contrast and color accuracy when working in strong lighting conditions.

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. The physical design features a brass bayonet mount, which offers rigidity and mounting precision along with a seal to guard against dust and moisture. Additionally, a rounded nine-blade diaphragm contributes to a pleasing bokeh quality.

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.
Short-normal prime is designed for full-frame Canon EF-mount cameras, however is also suitable for APS-C models where it provides a 64mm equivalent focal length.
Impressively bright f/1.4 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.
Three F Low Dispersion (FLD) and three 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.
One aspherical element is used to help limit distortion and spherical aberrations and also contributes 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.
Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, 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.
Specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates.
The bayonet mount is constructed from brass for ensured accuracy and durability. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.
Protective coating has been applied to the front element and is both water and oil-repellent to aid in cleaning.
This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.

Big and heavy but with great sharpness and a truly evocative, artistic look. Shots with this lens look magical.

I adapted this lens for use on a Fujifilm GFX100S and besides some occasional black corners that vary between soft and hard vignetting the sharpness of this lens is just astounding even at 100 megapixel! Even wide open at F1.4 the resolution is no less than native Fujinon lenses, IMO! The out-of-focus area is beautiful! On the larger GFX sensor it acts like a 32mm F1.1 full-frame equivalent lens. Chromatic aberrations and distortion is also completely absent. Considering pushing this lens way beyond it is indented to this is quite remarkable!

Great lens

This was purchased to replace a Canon 50mm f/1.4. First thing to notice is a big step up in sharpness, as well as bulk and weight. Auto-focus is adequate for cat portraits as long as they are sitting still. There is a chance that auto-focus is not dead-on at first try, repeatedly half pressing shutter button appeared to zero-in on the focus point. When using 5D4 in-camera HDR mode, during the second of the three consecutive exposures, I received an error code stating camera failed to communicate with the lens. I have to dismount the lens to clear the error. This phenomenon is repeatable using this lens. However, my 14-24 f2.8 works fine in HDR mode. As a third party lens, this Sigma has the optical feature I want at a very reasonable price and limitations that I can live with. Good job Sigma !

Hands down, the best lens in my case!!!

I have a $5,000 Canon lens that is not as sharp as this Sigma lens. This is easily the best lens for the money on B&H. Paired with my Canon C300 Mark IV, this Sigma lens makes documentary-style interviews look amazing. Thanks to Sigma for the glass and B&H for the deal! Cheers! W. Oliver

Highly recommended

If you're reading this, you have probably already read all the technical reviews of this fabulous lens. I bought an EF mount version to use on a Canon R5. Basically, that combination makes "soft" focus shots a thing of the past; it takes the whole notion of "missed" shots out of the equation. Yes, it is huge, and heavy. It's not a "travel" lens, or "walk-around" lens. I use it exclusively in the studio, with strobes, for portraiture; but that said, I could definitely see it being used by landscape photographers. I got it because I was interested in taking my photography as far as I could, technically. I think it achieves that purpose. The longer I do this, the more I am able to see, in my own photos. The Sigma Art lenses have their own "look" I think, having to do with the extreme sharpness, but also with the color and contrast (in comparison to Canon glass). One more thing I will add, that I think is important.....when you are using most lenses, even great ones, wide open or at very wide apertures, a common thing to see is axial chromatic aberration, which tends to destroy contrast. You won't see that when using this lens....which is why it seems so sharp, even wide-open. A bit of a chore to use due to the size/weight, but....very highly recommended.

Very good, indeed

If Sigma would also make 400mm f/5.6 lens of the same quality, everyone would praise Sigma. But Sigma does not see the value of the 300mm f4.0 lens, 400mm f/4.0, or f/4.5 or even f5.6 lens. Instead, Sigma is getting addicted to 10mm-1000mm no value zoom lens...

Autofocus using the Viewfinder is ACCURATE & CONSISTENT? Because many Sigma Art lenses are not good in this situation, even after tweaking with USB-Dock... Canon lenses are almost perfect and always reliable in terms of AF, but my experience with Sigma gave only about 50% real in-focus pictures WHEN USING the VIEWFINDER (on many cameras, no microadjustment related issue).

If you calibrate the lens with Sigma Dock and the focus is still off then you should use micro AF adjustment in camera

What is the focus throw (degree of rotation) from minimal to infinity of this lens? When doing manual focus, is the focusing speed linear? Thanks.
Asked by: Anonymous
It has roughly a 120 degree focus throw from minimum to infinity. Keep in mind that the lens itself has no hard stop and the focus ring can spin infinitely. Its focus speed is linear throughout its range.
