next PZ Lens Test Report - Canon EF 100-400mm f/4.5-5.6 USM L IS
#10
Thanks Marcus. I guess I fail to realize how thin the dof really is (even at small aperture for long lenses). I mean I think about dof when composing an image but having grown use to short lenses intuitively I don't sense just how thin it is @ 200mm or even 400mm.

Very nice image Wim; esp the one of the juvenile songthrush; the lighting really helps with emphasizing the details.

They do, but not because the lens is soft, it's just the very limited DOF at work here.



That's one of the lessons to learn with a long lens: there's hardly any subject flat enough to fit the DOF of a long lens, even if it's stopped down. This can be a real challenge in the field for both the photographer and the camera's AF.
