<p><strong>When are they coming?

</strong>I have confirmed that the new EF 200-400 f/4L IS 1.4x will indeed hit some retailers before the end of May, and for the others the first week of June. Canon Canada expects and is telling retailers that they will have limited stock on May 27, 2013 in their warehouse. Retailers will have theirs a few days later.</p>
<p>There will not be a lot of lenses available on the initial run, most reps are saying only “preordered” quantities will be available until at least the middle of July.</p>
<p>If you have your preorder in, it looks like you should expect your new lens quite soon.</p>

<p><strong>Canon still working on Foveon Technology

</strong>Canon has been working on 3 layer Foveon sensor technology for a while now, it still hasn’t appeared in a camera and we haven’t heard anything to say it will. However, the fact they continue to spend resources on it, tells us there is definitely a good application for the technology.</p>
