Canon 100mm f/2.8L Macro IS

Canon 100mm f/2.8L: Main Page

The Canon 100mm f/2.8L Macro IS is new offering in 2009 from Canon, presumably Canon’s answer to Nikon’s 105mm f/2.8 VR.

The unusually high number of elements for a “prime” lens (15 elements in 10 groups), the 100/2.8L is probably well corrected in a variety of ways, the main question being whether it can hold its performance from the 1:1 range out to infinity; some macro lenses perform not so well at infinity.

Lens overview

Overall image quality

Because the sample I began testing was badly blurred on one side, and the second sample also had an issue, it’s difficult to make an absolute conclusion about the 100/2.8L, but I think I have a good read on the lens, see the conclusions.

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.
