Canon 100mm f/2.8L: Infrared

For in-depth information on infrared, see the diglloyd Guide to Digital Infrared Photography.

Lens coatings on the EF 100/2.8L IS perform fairly well in infrared. However, in the f/11 -f/16 range (and wider apertures under some conditions), there is a significant hot spot effect which can be troublesome.

For more on hot spots and how to mitigate them, see the Guide.
