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
Canon Camera Connect Application. You can get it
