DPReview has posted an couple of interviews it has had with Canon executives. Once in late 2013 and another at CP+ last month. Most of the interview is about what you’d expect a Canon executive to say.</p>
<p><strong>On the topic of Smartphones</strong>

<em><span style="line-height: 1.5em;">“Realistically, thanks to the global prevalence of smartphones there are more photographs being taken. And as such I anticipate an organic growth of people who are using their smartphone and come to want to take better photographs. Regardless of what device they’re using, whether it’s a smartphone or a compact camera or DSLR, I’d like to encourage people to take more and more pictures.”</span></em></p>
<p><strong>On Canon being stagnant or boring

</strong><em>“They may perceive us in that way, but we are incorporating technological innovation into our products. The EOS 70D’s Dual Pixel AF technology is a good example of innovation that is unique to Canon.</em></p>
<p><em>Dual Pixel CMOS AF was born out of the concept of allowing the user to freely choose which kind of finder they wanted to use. The optical finder, the camera’s LCD or the screen of a mobile device via our EOS Remote app.”</em></p>
<p><strong>On 4K video taking over from true still images

</strong><em>“Yes, definitely. There will always be a need for still photographs, in my opinion. I believe that still images contain more information, and have more depth and meaning.”</em><strong>

</strong></p>
<p><strong>On the EOS M2 coming to North America or Europe

</strong><span style="line-height: 1.5em;"><em>“It’s a possibility but we haven’t made a final decision yet. We’re looking at the market.”</em>

Two separate folks have written in to say we should expect some kind of a DSLR announcement for NAB 2014 in April.</p>
<p>NAB is generally for Cinema EOS and other cameras that could be looked at as professional videography tools. For this reason, I have a hard time thinking the EOS 7D Mark II would be announced for this show, even if it is rumored to have cutting edge videography features. I think the camera will still fall into the prosumer still photographer segment with some bonus sales to videographers.</p>
<p>I think we’re going to be getting a lot of 7D Mark II information in the next little while, most of which being wishful thinking.  I’d bet on an announcement after NAB, with Cinema EOS products being announced for the show in late March or early April. We are told to expect 2 cinema lens announcements from a separate source.</p>
<p>We will see another round of PowerShot announcements, headlined by the SX50 IS replacement some time this spring, I think an EOS 7D Mark II announcement at that time is more likely.</p>
<p>This is also a Photokina year (we’ll be there), so I suspect we’ll see a big DSLR announcement in late August for that show.</p>
<p>More to come…</p>

<p>A new patent showing the 600mm f/4 optical formula. Is Canon already working on the replacements to the current super telephoto lenses? It’s quite possible! Although I suspect we’re talking 7-10 years from now. These sort of patents could also be for technology that will appear in  other lenses. Such as the upcoming replacement of the EF 800mm f/5.6L IS.</p>
<p>I do expect we’ll be seeing more DO lenses in the future. There seems to be an awful lot of patents for DO optical formulas. I suspect the cost of production is the hinderance to bringing these lenses to market at the present time. We already have <a href="http://www.bhphotovideo.com/c/product/973129-REG/canon_5176b002_ef_200_400mm_f_4l_is.html/bi/2466/kbid/3296" target="_blank">$11,000 200-400 f/4 lenses</a> and <a href="http://www.bhphotovideo.com/c/product/918849-REG/nikon_2205_af_s_nikkor_800mm_f_5_6e.html/bi/2466/kbid/3296" target="_blank">$18,000 800mm lenses</a>. I suspect we’re at the ceiling of what people will pay for a lens…. or not. :)</p>
