Aperture Series f/1.4...f/11 — Silver Canyon Pine
Even at distance, the artistic versatility of an f/1.4 lens is worthwhile. My preference in this series is for the f/2 or perhaps the f/2.8 result, in terms of which frame has the best visual impact; a blend of sharpness coupled with some vignetting and still-good separation of foreground from background.
This series should be helpful in understanding the vignetting and subject separation from background possibilities, as well as sharpness off-center even at this significant distance of perhaps sixty feet (19m).
The camera was tilted up slightly, so that we cannot expect the zone of sharpness to cut through the tree evenly. Tgether with possible mild field curvature at this distance means that sharpness of various areas should be understood in context of the overall framing.

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.
