<p>Although it is a niche market to say the least, the world of super telephoto lenses is a rather demanding one, with both sports and wildlife photographers depending on this massive and expensive glass to capture crisp images from far away.</p><p>Canon users seem to get a bit better treatment in this department than most, with prime glass ranging from their $11,000 400mm f/2.8L IS II to their $13,200 800mm f/5.6L IS. However, today's point of interest is going to be the glass that falls smack dab between those two, the 600mm range.</p><p>Dug up by CanonRumors, two new 600mm Canon lens patents found their way onto Egami. The patents detail two different models, and it's the second of the two that is proving to be the most interesting.</p><p>The first of the patents is a fairly standard 600mm optic, which likely won't be seeing the light of day anytime soon since the Mark II version of the 600mm f/4 was released in 2011 (more than a decade after the Mark I version in 1999).</p><p><a href="http://petapixel.com/2014/03/05/two-new-600mm-patents-from-canon-reveal-interesting-possibilities/">Keep reading...</a></p><p>Read also:</p><p><a href="http://www.photographyblog.com/previews/tamron_sp_150_600mm_f5_6_3_di_vc_usd_photos/">Tamron SP 150-600mm f/5-6.3 DI VC USD Sample Images</a> (PhotographyBLOG (blog))</p><p>Explore: <a href="http://news.google.com/news/more?ncl=dRHZ41YBv-OFErM3hXpzRcDsuOSuM&authuser=0&ned=us">3 additional articles.</a></p>
