      <description>&lt;P&gt;A lot would depend upon your location, meaning your altitude and flight speed.&amp;nbsp; Night time or day time?&amp;nbsp; I would want to stop down my aperture to f/5.6 to f/8, in order to take depth of field concerns out of the picture.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;A href="http://www.dofmaster.com/doftable.html" target="_blank"&gt;http://www.dofmaster.com/doftable.html&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;EM&gt;&lt;U&gt;I would go with a wide lens over a long lens.&lt;/U&gt;&lt;/EM&gt;&amp;nbsp; With a wide angle, you pre-focus at infinity, and everything would fall into focus beyond a few dozen feet.&amp;nbsp; A full frame camera's wider angle of view&amp;nbsp;would be an advantage over an APS-C camera.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;With long focal lengths, not only does focusing becomes a worry, air speed becomes with longer and longer lenses.&amp;nbsp; At most flight speeds, the ground is racing past you at fairly high speed.&amp;nbsp; Your images could become blurry at telephoto focal lengths.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;U&gt;&lt;EM&gt;Finallly, I would manually select just the center AF point&lt;/EM&gt;&lt;/U&gt;.&amp;nbsp; But, as I previously noted, if you use a wide angle lens focused at infinity, you could turn off AF on your lens and simply shoot away.&amp;nbsp; Besides, the camera may have difficulty focusing because it might hard under the circumstances to aim at one object long enough to lock focus properly.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>
