<strong>From Arthur Morris


</strong>Arthur has written a great article about getting f/8 autofocus with the new Canon EOS-1D X. A lot of birders used the EF 800 f/5.6L IS with the Canon 1.4x TC & EOS-1D Mark IV for example. The biggest complaint with the EOS-1D X has been the inability to get f/8 autofocus.</p>
<p>However, with the <a href="http://www.bhphotovideo.com/c/product/674565-REG/Kenko_PRO3001_4XDGXC_Teleplus_PRO_300_DG.html/bi/2466/kbid/3296" target="_blank">Kenko Teleplus PRO 300 DGX 1.4</a> teleconverter you can give the EOS-1D X the ability to autofocus at f/8 with the EF 800 f/5.6L IS. Another plus of using the Kenko teleconverter is you’re able to move the AF point at f/8. With the Canon teleconverter on say, the 1D Mark IV, you only had the center AF point active.</p>
<p>Arthur has posted lots of images to show the image quality that is possible with the Kenko 1.4x TC.</p>
<p><strong>From Arthur Morris</strong></p>
<blockquote><p>Once I got down in the mud I discovered that AF with the the Kenko Teleplus PRO 300 DGX 1.4x AF Teleconverter was fast and sure and accurate. I have been out every morning and afternoon since then and have totally fallen in love with the 1DX. That first afternoon I managed to get a huge gob of black, sticky, gooey much all over my brand new camera. It was a proper baptism.</p></blockquote>

<strong>A new 400mm suggested


</strong>There is a suggestion that we will see the announcement of a new EF 400 f/5.6L before Photokina in September. I would imagine such a lens would  include IS, but I guess  a lot of people assumed the same for a new EF 24-70 f/2.8L II.</p>
