Canon EF 16-35mm f/2.8L III USM

MTF for Canon 16-35mm f/2.8L III

Canon’s MTF charts are computed, not measured, and thus represent a best-case (real lenses have to be manufactured and always there are deviations of many kinds). Moreover, Canon’s MTF charts do not take into account diffraction—fantasy MTF. Still, the general behavior can be garnered from the shape and height of the curve.

See Reading and understanding lens MTF charts on Canon’s web site to understand Canon’s charts in particular.

The small size and crude resolution of the MTF charts provided by Canon makes it somewhat difficult to distinguish what is what. Apertures f/2.8 and f/8 are included, each with 10 line pairs/mm (thick lines) and 30 line pairs/mm (thin lines) and each with sagittal (solid) and tangential/meridional (dashed) lines—eight lines in total.

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.
