Post-season soccer provided an opportunity to test the 200-400 and 1DX III in some high ISO situations during a night game. I expected this to primarily be a day baseball/softball/soccer lens but with the 1DX III an f4 / f5.6 lens works well at night with the EF 200-400 providing extremely fast focus acquisition and accurate tracking even when light levels drop.
Shot @ 1/640, f5.6, ISO 40,000 (540 mm with the lever activated 1.4X switched in). RAW to JPG conversion in DPP with its standard NR.
I am really impressed with this lens.
