Just the 100-400. I own the Kenko 1.4x DGX Pro, however it doesn’t work all that well, even in good light. The image quality with the Kenko added is bad enough that it isn’t worth the effort, either.
All my shots for 2013 are just with the 100-400 plain. I’ve just honed my skill in using camo, creeping up, and waiting for the birds to come to me. Most of these shots are within a few feet of the MFD, usually from a very low perspective.
Very nice. Were these taken with your 100-400 alone or with a 1.4x TC added?
