1DX Mark II 1200mm Advantage...

[Arthur Morris]

Short-billed Dowitcher–fresh juvenile, feeding.

This image was created on my mega-JBWR morning, Wednesday August 17, 2016 with the the Induro GIT 304L/Mongoose M3.6-mounted Canon EF 600mm f/4L IS II USM lens, the Canon Extender EF 2X III,and the fast, rugged Canon EOS-1D X Mark II with 64GB Card and Reader. ISO 500. Evaluative metering at zero: 1/640 sec. at f/10 in Manual mode. Daylight WB.

One AF point up and three to the right of the center AF point/AI Servo Expand/Shutter Button AF as framed was active at the moment of exposure. The selected AF point fell on the bird’s face just below and to the right of the eye. LensAlign/FocusTune micro-adjustment = +5.

Advantage #1: Only with the 1D X are you able to utilize all 65 AF points (as well as all AF Area Selection Modes). With all other Canon bodies you are limited at f/8 to only the center AF point plus four assist points (in Expand). This 1DX II advantage allowed me to create a new and different image design at 1200mm with this image by placing the bird in the upper right part of the frame (with the reflections included below).

As for the image, please don't be shy; I'd love to know what you think about it.
