First time post. I recently purchased the 1DX and have been doing some very basic test shots. Although I love the higher ISO images, I am seeing what I believe is excessive red color noise in images shot within the lower range (100-400). In the photo I've posted, you can see splotchy red 'noise' above the horizon to the left of the surfers and along the cloud line between the sun and the buildings. I understand these are darker areas of the image but at ISO 200, this is quite surprising. Image quality was set to large Jpeg. I've also seen this in the RAW images as well. Am I expecting too much or has anyone else experienced this phenomena? Does this look normal to you? Any insights are much appreciated.
Make sure to turn off ALL extras on the SHOOT 2 Menu... Auto Lighting Optimizer is very bad. Long Exposure NR, OFF, HI ISO NR, OFF, Highlight Tone Priority, OFF
SHOOT 1. Peripheral Illumination, Disable
Chromatic Aberration, Disable.
Make sure your picture style is not over done. Like too much sharpening or contrast.
I must say I am happy with the camera but it has A LOT of trouble focusing against the sun. I am also getting too many out of focus images in normal situations. Even at F8.0. I don't use AI Servo. I never had with my 1D IV and I am getting too many useless images. I am posting a new forum entry to see if other people are having issues with focusing...
