Aperture Series: Mt Conness Green Meadow, Dusk
This in-depth analysis evaluates far-field lens performance from f/1.4 through f/9 in mountain shade (dusk). Best possible wide-open performance is shown unequivocally since peak focus can be viewed where it cuts through the grass, thus also allowing an evaluation of field curvature.
Stopped-down performance from f/2 through f/9 provides insight into the peak resolving power capabilities of the Sigma 105mm f/1.4 DG HSM Art as well as how much real depth of field gains with stopping down. It also speaks to focus shift.
Images at sizes up to full camera resolution.

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.
