<p><a href="http://www.northlight-images.co.uk/">Northlight Images</a> has spotted a couple of interesting image sensor patents from Canon, along with the USPTO patents for various Canon lenses.</p>
<p><strong>Image Sensor Patents</strong></p>
<ul>
<li>On chip A/D conversion [<a href="http://pdfpiw.uspto.gov/.piw?Docid=09219872&homeurl=http%3A%2F%2Fpatft.uspto.gov%2Fnetacgi%2Fnph-Parser%3FSect1%3DPTO2%2526Sect2%3DHITOFF%2526p%3D1%2526u%3D%25252Fnetahtml%25252FPTO%25252Fsearch-bool.html%2526r%3D4%2526f%3DG%2526l%3D50%2526co1%3DAND%2526d%3DPTXT%2526s1%3Dcanon.AANM.%2526OS%3DAANM%2Fcanon%2526RS%3DAANM%2Fcanon&PageNum=&Rtype=&SectionNum=&idkey=NONE&Input=View+first+page" target="_blank">USPTO</a>]</li>

</ul>
<p>As we’ve said a lot over the last while, we do expect some big jumps in Canon sensor technology.</p>
<p><strong>Canon Lens Patents</strong></p>
<ul>
<li>Canon EF 16-35mm f/2.8L III [<a href="http://pdfpiw.uspto.gov/.piw?docid=09217851&SectionNum=1&IDKey=014B9F8A0796&HomeUrl=http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2%2526Sect2=HITOFF%2526p=1%2526u=%25252Fnetahtml%25252FPTO%25252Fsearch-bool.html%2526r=39%2526f=G%2526l=50%2526co1=AND%2526d=PTXT%2526s1=canon.AANM.%2526OS=AANM/canon%2526RS=AANM/canon" target="_blank">USPTO</a>]</li>
<li>Canon EF-S 15-105 f/2.8-5.6 [<a href="http://pdfpiw.uspto.gov/.piw?docid=09217849&SectionNum=1&IDKey=80815EB856F5&HomeUrl=http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2%2526Sect2=HITOFF%2526p=1%2526u=%25252Fnetahtml%25252FPTO%25252Fsearch-bool.html%2526r=40%2526f=G%2526l=50%2526co1=AND%2526d=PTXT%2526s1=canon.AANM.%2526OS=AANM/canon%2526RS=AANM/canon" target="_blank">USPTO</a>]</li>
</ul>
<p>The EF 16-35mm f/2.8L III continues to make an appearance and we were recently told that the new lens is <a href="http://www.canonrumors.com/canon-ef-16-35mm-f2-8l-ii-replacement-in-the-wild-cr2/">in the hands of select photographers</a>.</p>

Re: Image Sensor & Lens Patents from Canon

I've been FF for several years now, but loved the EFS 15-85 on my 7D. So, I am most interested in improving the sensor tech on the 5DIII...but I have to say, if the EFS 15-105 has the same or even better IQ as the EFS 15-85, that would be an incredible walk around lens for crop sensor users.

I concur. I love my 15-85! If they can match its IQ on this new lens, I'd be very interested. I just hope it's a ring type USM focus, rather than STM though. ??? STM is a GREAT replacement for the micro-motors on the less expensive lenses and also for video shooters, but I'd prefer a USM setup for higher end E-FS lenses. Sometimes I worry that Canon is going to only use STM on all E-FS lenses moving forward, and that will be a real shame if they do. STM is superior to micro motor, but ring type USM still rules the high end lenses for stills.

The 24-70 2,8II is here now and is awesome, why wait

Interesting to see a patent for 15-105mm

I would prefer an EF-S 15-70mm F2.8-4, which makes a pair with the mayor 70-200 and also 70-300.

Not wide enough for crop. Heck for even FF on Landscapes and cityscapes its not wide enough.

I'd prefer a 15-70mm too but with constant F2.8 and IS

Why stop there? I want a 10-600mm with constant F1.4 and IS

Because your lens would be much bigger than this:

AND, my dream is closer to possible than impossible.
Sigma already makes 17-70 F2.8-4
They also make 17-50 F2.8
Even Canon makes 17-55 F2.8
Both Sigma's and Canon's 2.8 for APS-C also have IS.

If Sigma can make 18-35 F1.8... How hard is it to make 15-70 f/2.8???
Hey, I will even settle for a 17-70 F2.8 IS
