Sigma 105mm f/1.4 DG HSM Art Lens for Canon EF: A Detailed Description
The Sigma 105mm f/1.4 DG HSM Art Lens is a masterpiece designed for discerning photographers who crave exceptional image quality, stunning bokeh, and precise control over their compositions. Here's an in-depth look at this remarkable lens:
Focal Length and Purpose:
- The 105mm focal length places it squarely in the portrait lens category. On a full-frame DSLR, it hits the sweet spot for portraiture, providing a natural perspective and ideal working distance.
- APS-C format users can also benefit from this lens, though they'll need to adjust for the crop factor. Even on APS-C, it's excellent for tightly framed portraits.
Aperture and Bokeh:
- The f/1.4 maximum aperture is where the magic happens. It allows for incredible low-light performance, beautiful background separation, and that coveted creamy bokeh.
- When shooting wide open at f/1.4, the lens renders backgrounds into dreamy, painterly washes of color. It's the "bokeh master" Sigma claims it to be.
Optical Construction:
- The lens comprises 17 optical elements arranged in 12 groups—an unusually large number for a prime lens. This complexity ensures outstanding image quality.
- Special glass elements, including aspherical and low-dispersion glass, minimize aberrations, distortion, and chromatic fringing.
- Sigma's multi-layer coatings reduce flare and ghosting, enhancing contrast and color fidelity.
Build Quality and Features:

- Canon and Sigma versions can be adapted for Sony E-mount using the Sigma Mount Converter MC-11.
