Aperture Series @ 24mm: Lloyd on Bleached Aspen Log
This series at 24mm confirms and extends the results seen at 22/23/24mm.
I took this series to see how well the Sigma 14-24mm f/2.8 DG HSM Art performed in terms of subject separation, in a vein similar to what I had done for the Zeiss Loxia 24mm f/2.4 in Zion Kolob Canyons.
I had not intended to publish this series, but it is a striking demonstration that to the extent the Sigma 14-24mm f/2.8 DG HSM Art is outstanding at 14mm, it falls to pieces at 24mm, so much so that it is the best demonstration of all the series in the 22-24mm range at showing the weakness of the lens at 24mm.

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.
