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.

Stunningly well-corrected, this optic will help you produce beautiful images. I compared it to a Voigtlander 40 pancake lens, and while the smaller lens excels in portability, the larger Sigma yields sharper, contrasty pixels, corner to corner, & smooth bokeh, regardless of aperture: Much better. This is not your father's or grandfather's standard lens, and I like the color production, too.

Looks great . . not as quick as Sony lens with eye tracking AF.

After years of using a number of 28mm to 35mm lenses that cost much more, the Sigma 40mm f/1.4 Art is now my favorite. This lens produces edge to edge, sharper images with great contrast and practically no distortion.

It Ruins My Other Lenses

I cannot say enough good about this lens... it makes me wish my other lenses were as nice. It is razor sharp and has very nice contrast. The bokeh is very smooth and pleasing. I am happy to carry it around... LOL... that is how nice it is.

This lens epitomizes what one would consider an artists lens that defies the normal technical parameters you would normally use to explain its attributes. In this case I will specify the camera ( Lumix S1r ) and the subject ( multiple selections of colorful and challenging flowers, translucent whites to rich saturated blooms all mixed ). I will not include an image because the reproduction would never do it justice here however, the following is how I perceive this lenses magic in transforming imagery. This lens is like a Parisian enchantment vs a German romance of technology. Translucency is beautifully detailed velvet with transitions of color and contrast elegantly rich yet smooth. The lens shot under morning light with proper subject with transfigure your imagination into an honest magical reality. This review may be panned by many for its seeming frivolity, yet it is the best I have to offer explaining the consistent results I have attained. A real artists lens in the right hands, most powerfully used wide open. Just my thoughts.....( note I own 17 different lenses designed for the L system ) P.S. technical features are excellent including AF.
