Having had a variety of cameras and lenses and t.c’s over the years from canon,Nikon, kenko, sigma I found that some are good and some most definetly are not . 
    These days I’m on olympus and there 1.4t.c works quiet well even fitted to my apeture limited 100-400 lens BUT caveat emptor I’m now on third copy of one the first two giving differing i.q this one does work quiet well even at F9 which is wide open with the big lens .. but it does give nearly 1200 mm of reach in full frame terms and thanks to olympus I.b.I.s and I.s ability is hand holdable

Yes that’s very true. In fact it’s also true about lenses as well as tc’s. I recall trying 3 versions of a Nikon f2.8 (expensive!) zoom lens just after digital took off, before I got one that didn’t give chromatic aberrations (fringing) in high contrast areas.  The local dealer was a bit bemused and probably thought I was being a bit anal, but when you are paying £1500 for a lens (20 years ago!) it needs to be worth it.

The Olympus set up would seem to be ideal for birding.
