7D replacement will not be called 7D Mark II because it will be APS-H

It will be a 1D Mark V in a 7D size body, hence the change to 1Dx because it is full frame.

A Canon Rumors reader “JerseyShooter” has been working with Sigma to improve the performance with Canon’s APS-H flagship cameras, the EOS-1D Mark III & EOS-1D Mark IV.</p>
<p>Back in October of 2013, JerseyShooter started a blog documenting the issues he was having with the lens on a blog. He worked directly with Sigma and it looks like it has paid off with the firmware that was released yesterday to improve the performance with both of the mentioned cameras.</p>
<p>There have been other issues with the lens that he is documenting on the blog as well.</p>
<p>For the record, JerseyShooter is an employed professional photographer.</p>

A patent showing a 5 layer image sensor from Canon has appeared. UV and IR layers help with color reproduction especially for skin tones.</p>
<p><a href="http://www.northlight-images.co.uk/cameras/Canon_rumours.html" target="_blank">Keith at Northligh</a>t has this to add about the patent: <em>“The pixel structure above, shows a BSI design (back illumination), but obviously no pixel structure. Extending the range of light response to UV and IR would cause issues for current lens designs, but the idea of more than three colour primaries is not new, although it would require a major re-write for support from RAW converter software.”</em></p>
