The Sigma 50/1.4 EX DG offers a very nice combination of bokeh, sharpness and clean imaging across the frame. It offers outstanding field illumination, and seems to be optimized for closer range and wider apertures.
At 1/3 the price of the Canon EF 50mm f/1.2L, it offers outstanding value. This lens acquitted itself well enough that I would consider buying one, especially for low-light shooting at f/1.4 - f/2, and I’d advise anyone considering the Canon 50mm f/1.2L to give the Sigma 50/1.4 a close look. For one thing, the Canon offering has such strong focus shift that the Sigma is likely to produce sharper results in the f/2 - f/4 range for that reason alone. For another, the illumination at f/1.4 is highly competitive with the Canon 50/1.2L stopped down to f/1.4.

Diglloyd DAP is DSLR-oriented, but also contains workflow and other topics. Much of the focus is on Canon and Nikon but also Pentax and Pentax medium format.
Special emphasis is placed on lens evaluation, focusing on Canon and Nikon and Sigma lenses, but with a few others like Rokinon/Samyang.
- Make better images by learning how to get the best results right away.
- Save money by choosing the right lens for your needs the first time, particularly some of the new Sigma Art lenses vs Nikon and Canon.
- Workflow discusses image organization, raw conversion and post processing. Many examples show processing parameters for direct insight into how the image was converted.
- Jaw-dropping image quality found nowhere else utilizing Retina-grade images up to full camera resolution, plus large crops [past 2 years or so].
- Real world examples with insights found nowhere else. Make sharper images just by understanding lens behavior you won’t read about elsewhere.
- Aperture series from wide open through stopped down, showing the full range of lens performance and bokeh.
- Optical quality analysis of field curvature, focus shift, sharpness, flare, distortion, and performance in the field.
