An African wild dog, subduing an impala, northern Botswana. Image with the EOS 1DX Mark 2. Shutter speed 1/1600sec at f6.3, iso 1600, lens EF 100-400 IS ii. Not necessarily the most aesthetically pleasing image but a dramatic scene instead. While the dog was battling the impala, the rest of the pack had run in a different direction. With such clean image quality especially in the iso 1600 to iso 3200 range, the 1DX Mark 2 allows me to maintain a fast shutter speed in the case of more action, and stop down a bit to get both animals sharp..without any penalty for using the higher iso settings. Cropped from 20mpix to 13 mpix, and raw image processed in LR and downsized to 1500 pixels wide for web
