<p><strong>*UPDATE 2*
</strong>Another suggestion from a man who <a href="http://www.lensrentals.com" target="_blank">knows everything about lenses</a>. He thinks it’s a “28-300 with filter barrel removed”.</p>
<p><strong>*UPDATE*
</strong>It seems most people think it’s the Sony 70-200, though the body does look like a Canon.</p>
<p><strong>I’m not sure
</strong>Below is an image posted on the Google Plus account of Peter Norvig. In the low resolution image, a lens that I don’t recognize is being used. I have compared it to the 28-300L, 100-400L and 70-200L and it doesn’t match up with any of them.</p>
<p><strong>Says Peter
</strong><em>“For Canon fans, you might find this exciting. A photographer was using this lens. I assert that the black stripes of the focus and zoom rings are the wrong width and placement to be either the 70-200 or the 100-400; therefore I speculate this is a prototype of the long-rumored 100-400 II.”</em><strong>

<p>What do you guys and gals think?</p>
