Examples: Lundy Canyon Portraits
These examples shot in Lundy Canyon in December 2018. They are all personal images of my daughter and/or my daughter and/or myself. I present them as highly relevant to anyone looking for one of the best lenses for people photography that I’ve ever had the pleasure of using.
There were challenges shooting the Sigma 40mm f/1.4 DG HSM Art on the D850: (1) frequent autofocus errors (frontfocus) along with (2) the focus shift of the Sigma 40mm f/1.4 DG HSM Art. Happily, these two factors often cancel each other out if shooting stopped down a little, and the D850 unwittingly cooperates even more with small autofocus errors limitations, e.g., picking out eyebrows instead of the iris of the eye, so that a little focus shift is just right. Accordingly, shooting at f/2.8 through f/8 delivers excellence much all the time.

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.
