This test is of a landscape scenario at mid-range focus. The mid-day lighting was a good time of day to put aside creative photography and make a comparison under harsh but reasonably consistent lighting.
The scene was chosen to provide a near/far perspective, to show off any field curvature issues. With crappy focusing mechanics as well as aberrations, matching focus perfectly is a difficult task, so a near/far scene helps show off variations.
I shot another scene elsewhere on a different day elsewhere, with similar results.
Focus was just above center near a small white patch of snow.

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.
