Canon 200mm f/2L IS

Aperture Series and Bokeh at f/2, 4, 8 (Flowers)

This pages shows the same image taken at f/2, f/4, f/8; three frames, with each frame doubling the depth of field of previous frame.

This demonstrates the effects achievable at each aperture, and shows why shooting at f/2, might be your best choice with some subjects, in order to isolate the subject. It also shows how pleasing the 200/2L IS remains when stopped down.

Aperture series

Already at f/4, the subject competes with a distracting background. The added depth of field of f/4 or f/8 does nothing for the image except to make it visually distracting. An f/2.8 lens would strike a middle ground, but would not afford the same possibilities.

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.
