Just curious what lens did you use?
Wonderful and sharp photo BTW
Thanks rmalak, I was set up for birding, the lens was 200 - 400 1.4x f/4 @ 560mm. 1/160 @ f/5.6 ISO 1600. The light was starting to fade at about 18:30. Mounted on a sort of gimbal arm bolted to the seat, like a game fishing rig, but for cameras.
