We’ve been told that Canon is working on revisions to “some” of the big white lenses for a 2018 release. Beyond the <a href="http://www.canonrumors.com/canon-ef-600mm-f4-do-is-to-arrive-in-late-2017-cr2/">new EF 600mm f/4 DO IS</a>, which we’re told could be announced in late 2017, Canon does plan for some “minor” revisions of the current lineup. Weight reduction and a new IS system is apparently the goal from the new lenses.</p>
<p>2018 is an Olympic and World Cup year, and Canon tends to release or at least test pro gear during those times.</p>
<p>When were the current non-DO big white lenses announced?</p>
<ul>
<li>Canon EF 200mm f/2L IS 2008</li>
<li>Canon EF 200-400mm f/4L IS 1.4x 2013</li>
<li>Canon EF 300mm f/2.8L IS II 2011</li>
<li>Canon EF 400mm f/2.8L IS II 2011</li>
<li>Canon EF 500mm f/4L IS II 2011</li>
<li>Canon EF 600mm f/4L IS II 2011</li>
<li>Canon EF 800mm f/5.6L IS 2008</li>
</ul>
<p>The current iterations of the 300,400,500 and 600mm lenses came 12 years after the previous versions. Which makes a 7 year upgrade cycle seem a bit quick. The possibility of a new 200 f/2L IS and EF 800 f/5.6L IS seem a bit more likely. However, the latter have the lowest volume of sales of the entire series of non-DO “big white lenses”.</p>
<p><em>More to come…</em></p>
