Portrait of the Canon 100mm f2.8L hybrid IS as a two-sided lens
Critically-acclaimed lens-review site PhotoZone.de has posted a two-sided review of the Canon 100mm f2.8L hybrid IS lens. Just like the old 45mm singles, side A reviews the lens as a (35mm) full-frame lens, and side B reviews the lens as an APS-C lens. The "carriers" of this test were the Canon 5D Mark II and Canon 50D.
As usual, we won't reveal their conclusions here, but if you are pressed for time, jump to page #3 of the full-frame review to see the conclusions along with the full-size review images.
