This image of a captured and posed chameleon was created on my recent Tanzania Photo-Safari at Ngorongoro Crater with the tripod-mounted Canon 200-400mm f/4L IS lens with Internal 1.4X TC, an external 1.4X III TC, (with the internal TC in place at 784mm) and the EOS-1D X.
ISO 1600. Evaluative metering +2/3 stop: 1/160 sec. at f/14. On-camera "fill flash" at +1 2/3 stops.
Can anyone explain why this is fill flash rather than flash as main light and in the same vein, explain why so much plus compensation was needed?
As for the image, don't be shy; all comments welcome.
As for the subject, it was of course returned to its natural environment after a short photo session.
As for the lens, it is amazingly versatile. With it's .15X magnification (.21X with the TC in place) and its 2 meter (6.6 feet) close focus it can serve as a quasi-macro lens with medium and large sized subjects.
You can see all Canon telephoto lens specs here (http://www.birdsasart-blog.com/2012/04/24/canon-telephoto-lens-specifications-info-and-links-bookmark-this-page/). For this image I added the external TC as there were several photographers jockeying for position. Fortunately many of them were kneeling so by adding the TC I was able to shoot over them. You can see some wide Serengeti plains images made with the 2-4 and learn of my harrowing trip home here (http://www.birdsasart-blog.com/2013/08/20/43-hours-door-to-door-with-a-bad-head-cold-you-gotta-love-it-2/).
I have been and will be posting dozens of Galapagos images made with the 2-4 and have begun posting images from the Africa trip made with it. The 2-4 is the only big lens I am taking on my upcoming Bear Boat and Dahlia IPTs. You can visit the blog here (http://www.birdsasart-blog.com/) and scroll down or hit Postlist/2013 to find a ton of 200-400 images. Or follow the link to the Bulletin Archives. Only Bulletins 445 & 446 contain 200-400 images. I will be doing a blog post on which big lens (or lenses) to bring on a given trip for the Canon Digital Learning Center Blog here (http://learn.usa.canon.com/dlc/blogs/blogentries.spr) soon. And that will be followed up with a Focus On feature for the DLC website (http://learn.usa.canon.com/home/home.shtml).
