I*ve always been a big fan of using extenders, and those that say great images aren*t possible with them have a personal invitation to come round to my office and peruse my archives. Many of my best photos have been taken using extenders, and I recently showed you guys that even cheaper (and by cheap, I mean relative to super tele primes) zoom lenses like the stunning Canon 100-400 f/4.5-5.6 L IS II, can work exceptionally well with a 1.4x extender.

Recently I*ve been carrying my Canon 400mm f/4 DO IS II around with me a lot. You can do that with this lens, simply carry it around just in case an opportunity presents itself. It*s a distinct advantage over all of Canon*s other super telephoto lenses, because the others are so big and cumbersome that they require some forethought and often a different carrying solution. I*d simply never carry my big 200-400 f/4 around with me unless I really knew that I was going to use it. Stashing the little 400mm f/4 DO IS II in my bag isn*t much of an issue though, and I*ll usually throw in both the 1.4x and 2x extenders as well.  This gives me a 560mm f/5.6 option, and an 800mm f/8. With the 5D Mark IV*s new AF system, all AF points are active with with an f/8 lens, so I still get great compositional flexibility.

There*s two incredible things about this setup: Firstly, that*s an easily hand-holdable 800mm lens!!  And secondly, it*s STUNNINGLY sharp! In fact, I think this might be the best performing Canon lens ever, with the 2x extender.

Usually I*ve no issues at all with using a 1.4x extender on a super telephoto lens, but in general, to use the 2x extender I try to limit myself to using it in really ideal circumstances. Nice contrasting, bright light for example, because the 2x can lower contrast a fair bit on some lenses, and this reduces perceived sharpness. When I first tried the 2x extender on the 400mm f/4 DO II though, I was staggered. This is a combination I could use all day long, and not worry about sharpness at all.
