Noise is extremely well controlled in this ISO 3200 image. There's only a hint of luminance noise in the background visible at 100% on screen in this shot which was taken with the high ISO noise reduction setting set to its default 'Standard' setting.
This ISO 1000 image has recorded the fiddler's face in fine detail.
This JPEG image was captured at the same time as the raw file below, note the higher contrast which results in the loss of some detail in the shirt as the dark gradation is compressed.
The raw file has preserved more of the tonal gradation in the dark shirt.
The full-frame sensor and a large aperture (f/3.2) has resulted in shallow depth of field so the runner is isolated from the background.
The autofocus system is responsive and accurate.
Even in Evaluative mode the iFCL metering system puts emphasis on the subject under the active AF point, but it still manages to find a good balance when the subject is darker or brighter than mid-grey.
Detail, and colour are great in JPEGs straight from the Canon EOS 1DX.
Even as the light was falling, the Canon EOS 1DX was able to capture lots of detail, meter accurately and reproduce colour well.
Colours are represented well from the Canon EOS 1DX.
Lots of detail can be captured by the Canon EOS 1DX: this image was shot using a 100mm macro lens.
The Canon EOS 1DX deals well with mixed lighting conditions, producing accurate colours under the Auto White Balance setting.
Shot at ISO 25,600, noise is controlled well for such a high sensitivity. Examining the image at 100% reveals chroma and luminance noise, but the image looks great at printing and web sizes.
This image shows the extreme sensitivities the Canon EOS 1DX can reach and was shot at ISO Hi2. Obviously the image degradation is severe, but it's also important to remember that this was shot in near dark conditions.
This image again shows how the Canon EOS 1DX has coped with a mixed lighting condition, to produce accurate metering throughout the scene.
