This series is a visualization tool for bokeh and sharpness of the Canon EF 85mm f/1.2L II across its aperture range, particularly for sharpness in combination with bokeh.

Shot with the 22-megapixel Canon 5D Mark III at ISO 200. The Canon 5D Mark III has a fairly noisy sensor and this is evident at ISO 200, even though a 0.2 stop pull was done here. Regrettably, the noise diminishes the beauty of the background blur smoothness.
Take time to observe the interplay of sharpness versus blur; to my eye using f/2 - f/4 delivers an exceptionally pleasing effect with razor sharp subject and nicely blurred background in which color bokeh (secondary longitudinal chromatic abberation) is minimized, especially by f/2.8 - f/4.

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.
