Testing Canon EOS 5D Mark IV with EF400mm f/5.6 USM + Tamron SP 1.4x teleconverter

Testing telephoto lens EF400mm f/5.6 L USM + Tamron SP 1.4x white teleconverter at my backyard.
I removed the tape that cover the 2 pins (that I used in 50D camera, so that fool the camera for center auto-focus-non reporting aperture data).
Canon EOS 5D Mark IV have no problem with Tamron 1.4x TC, excellent AF at f8, not only in center but all the 21 cross AF points.

Greater Coucal in flight with Canon EOS 5D Mark iv

I'm testing EOS 5D Mark IV with UVA (ultra-wide angle) 17-40mm f/4 L zoom lens at backyard, when this Greater Coucal pass by.  Here is a quick reflex one shot at 36mm. That 5D mark iv AF is really fast . I will test it again with 400mm f/5.6 + Tamron SP 1.4x teleconverter later. Can it focus at F 8?
Here are a two samples of 5D Mk IV pics with 17-40mm f4 lens.

I shot in RAW format, and download the files using WIFI and a Camera Connect Application. The 5D Mk IV auto-convert to JPEG files to iPhone, very easy.
The above pic is at 40mm f/5.6, and below at 17mm. Original colour, no processing , just resize for blog
