I did not let that request keep me from making a few of my beloved head portraits.    <\/p>\n<p>With the set-up above I was working at approximately 29X maginfication.   Even when handholding I felt confident that I could make at least a few sharp images at 1\/1000 sec.  It is only possible to hold the lens up for 10-20 seconds at a time so I rested it on a deck chair until Jiim had the boat in perfect position.<\/p>\n<p>Many folks do not understand that with the 800 being an f\/5.6 lens that once I add the 1.4X TC the central AF sensor is the only one available (and that only with a pro body&#8230;.)  With the wind up a bit the boat was rocking; I knew that keeping the sensor on the bird&#8217;s head would be a challenge so I quickly set CFn III-5 ( Lens drive when AF impossible) to &#8220;1: Focus search off.&#8221;  This prevents the system from searching for the background when the sensor momentarily falls off the subject.  In addition, I was hoping to make an image that featured the baby bird&#8217;s head in the lower right corner of the frame.   The last thing that I wanted was to have the AF system search for the distant trees.  So setting CFn III-5 to 1 had two probable benefits; my plan worked to perfection and I was able to capture the image that I had visualized \ud83d\ude42<\/p>\n<p>Both the Mark IV and the 7D Guides are chock full of such tips, tips that will help you to create better images on a consistent basis.
