actually, 100-400 is good versatile lens, can be used for general purpose as well! i have a 400mm f5.6 that i use exclusively for birding for a while now, although a very sharp and fast focusing prime, but i find it bare minimum reach for that purpose. the new canon tc 1.4xIII helps somewhat but not a panacea. for birding you get the longest FL you can afford. i have just ordered a canon 600mm f4 II and a 1Dx camera that will be waiting for me when i come home from my trip overseas in a couple weeks and i can hardly wait now that plus new canon tc 1.4xIII/2.0x III (which i have both) should give me plenty of reach to those feathered critters

cheerz.

Sorry for the thread drift, but I have a question.  Will the 1.4x TC III work with the 100-400 without taping contacts?  I was/am under the impression that AF won't work.

depends on what camera you are using, if you are using the canon 1D professional cameras or 5DIII with the latest firmware, then yes, a tc 1.4x will autofocuss using a 100-400 or 400 f5.6 lenses.

cheerz.
