Canon 16-35mm f/4L IS

Distortion at 16mm

The distortion is a standout behavior that won’t go unnoticed: it makes the 16mm setting unusable for architecture or even landscape photography incorporating a level horizon—at least without distortion correction. Nikon’s 16-35mm behaves similarly.

Zooms in general tend to have barrel distortion at the wide end and pincushion at the long end. Ultra wide angle zooms generally have strong distortion at the wide end, though Nikon’s 14-14mm f/2.8G is a standout for relatively low distortion.

Correcting distortion in Adobe Camera Raw

At the time this was written, Adobe Camera Raw did not yet offer a lens correction profile for the 16-35mm f/4L IS, but applying the 16-35mm f/2.8L II profile does an imperfect but reasonably good job.

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.
