Aperture Series: Map of the World (Pentax K-1 SuperRes + StdRes)
A macro lens should perform at very high level in macro range, along with a flat field (strictly controlled field curvature). This finely detailed map was shot at a reproduction ratio of 1:10.2 to test just such a case.
SuperRes pixel shift mode of the Pentax K1 was used, for maximum image quality.
Focusing: relying on autofocus is a recipe for disaster on the K1, as was immediately proven by initiating AF, then zooming in, to see an obviously blurred image. Manual focus was used instead, and the scene was shot twice to verify peak lens performance.
Image sizes up to 28 megapixels along with large crops provide a detailed look at the “whole package” (lens and camera).

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.
