Here are a couple of shots of the Reddish Egret that walked by me as described in my last post. It pays to take shorebird photos from the prone position. Only minor cropping required.
Taken with Canon 1DX with Canon 500mm F4 IS II and 1.4X III teleconverter mounted on Skimmer ground pod with Wimberley II gimbal head
1/400 sec @ F11, ISO 1600, evaluative metering, +1 exposure compensation, 700mm
1/1000 sec @ F11, ISO 1600, evaluative metering, +1 exposure compensation, 700mm
