Aperture Series: Upper Reaches of Lundy Beaver Pond, early November
This scene is extraordinarily challenging for any lens, with extremely fine detail across the frame. Weaknesses of any kind are readily revealed by such a scene: sharpness and micro contrast, field curvature, color aberrations. It is also an excellent scene for verifying lens symmetry as well as showing that sharpness at the same distance can vary widely.
Due to ultra-fine detail, this series is difficult to appreciate on a conventional display. Evaluation and viewing on an iMac 5K or similar ultra high-res display is strongly recommended.

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.
