This California Brown Pelican was photographed on Wednesday morning past in La Jolla, CA with the 70-200 f\/2.8L IS II lens, the 2X II TC, and the EOS-7D hand held at 342mm. (You gotta love the versatility of zoom lenses.) ISO 400. Evaluative metering +1\/3 stop: 1\/2000 sec. at f\/5.6 in Manual mode. Bright sun fill flash at 0. <\/p>\n<\/td>\n<\/tr>\n<\/table>\n

Canon 70-200 with the 2X II TC and the EOS-7D<\/h2>\n

With all the success that I have had with the new 70-200, the 2X, and the Mark IV, folks have been clamoring for info on how the new lens and the 2X II TC would do with the 7D. I used the 7D on Wednesday morning after the sun broke through with the 70-200 f\/2.8 IS L II and the 2X. For images of static subjects the combo performed superbly. I had only a few chances with birds in flight, too few to offer any substantive opinion…. <\/p>\n

Folks need to realize that with the 1.6X multiplier effect of the 7D that it will be more difficult to hold the rig steady than with the Mark IV with its 1.3X multiplier effect: 640 compared to 520. And errors of equipment shake are multiplied by the square of the focal length, not by the focal length alone. This of course goes quadruple for folks who are hand holding. Do not think that you can go out with the new 70-200, the 2X TC, and your 7D and make sharp images in any light without using a tripod. You need to have superb sharpness techniques when hand holding this combo. And lots of shutter speed. And you need to understand how your choice of AF mode (One-Shot or AI Servo) will influence focusing accuracy and therefore image sharpness…. <\/p>\n

The image above, however, shows that the combo can produce superbly sharp images in the right conditions when used by folks who know what they are doing. <\/p>\n

One note about flight photography: in most flight situations, there would be little need to use the 2X II TC with the 70-200 and the 7D. With the 1.6 multiplier effect of the camera all that you will need most of the time for hand held flight photography is the 1.4X teleconverter. And I have no doubt that that combination will acquire focus quickly, track accurately, and produce a high percentage of razor sharp on the eye images….<\/p>\n

You can learn how to better use your 7D by purchasing a copy of our 7D User’s Guide<\/a>. For this image I had set a different focusing sensor for vertical camera orientation. Learn how in the 7D UG. The update will be sent very soon. <\/p>\n

I fly to Albuquerque, NM to pick up Denise Ippolito and Peter Kes. The Bosque IPT begins tomorrow night. If you are in the neighborhood and would like to attend the introductory slide program as my guest, be at K-Bobs at about 6:45 pm. <\/p>\n
