This little lady was hopping around on my backyard fence for several minutes with these green berries in her bill. The shot was taken with the 100-400 at 400mm, and a Kenko 1.4x Teleplus Pro 300 TC. The exposure was 1/250 sec at f/5.6.

Nice capture here with great BG and the weatherd fence makes for a nice perch.Nice detail in the bird.

Even if your EXIF data says F5.6 it should be F8 as the 1.4x tc will bump it up 1 f Stop

Good point about the TC and f-stop. There is one stop less light available to make the exposure. The TC does not affect the depth of field in the same way, does it? That is, I don't have the same DOF here as I would with an equivalent lens set to f/8, do I? I have never seen a discussion of TCs that addressed DOF (not that I have really looked).

Thats a good question and I would assume that as the aperture narrows it would provide more DOF regardless. A good question for the Accsesories and gadgets forum.
