Again, nothing like what you guys are posting, but I'm just enjoying the AF performance of the 1DX/70-200 f/2.8L II IS performance. Auto ISO with CWA on the 1DX nailed the exposure pretty close too. This is a Tiffin pole vaulter at the GLIAC Outdoor T&F Championships on Thursday. 1DX, 70-200 f/2.8L II IS at 95mm, 1/5000s, f/3.2, ISO 100.
