The 1.4 TC would be a nice addition if you wanted to do contrail spotting or get the extra range while spotting.
This shot was taken with the 100-400L and a Kenko 1.4 TC and that is some good result IMO!
I was hoping to get the 70-200f/2.8L and 2x but I think i'll get the 100-400L since aviation is my prime subject! The following shot was taken Friday with a 90% crop, 1200px wide, I can read the registration. That's pretty good. So 1.4 TC would get you even closer which would be nice for contrails which are further. The thing I noticed yesterday though was that the push pull was hard to use, I tried to make it less tight but had difficulties nevertheless. Perhaps the copy I used was the problem?
