This newly announced Canon lens has a 1.4x extender built in. Add that to my Canon 7D sensor and you have 320mm-896mm full frame equivalents. Add that to a Canon T3i with it’s 10x crop mode video and you get something insane and no way possible good quality. Interesting though. Canon also announced 500mm and 600mm telephoto lens way out of my price range.
