I saw your post on that other forum and those people are generally nice but technically challenged, so I am answering you here. The 5D3 has in camera correction for vignetting, chromatic aberration and 4 selectable levels of noise reduction based on the ISO. The vignetting correction seems to be complete but it will not fix something caused by a random filter or some wierd aftermarket hood.
By the way, these corrections only apply to jpegs. They are just metadata added to the raw files for Canon's DPP to read or the camera to read. They do not change the raw data at all. If you process the raw files to jpeg in camera or in Canon DPP you can also correct for lens distortion. Hope that answered your question.

Hi,
I am about to buy a 5D MK3 with it's kit lens (24-105). I know it has in-camera correction for vignetting (light fall-off if you prefer) as long as the lens data is loaded onto the camera (in this case it would be).
What I am trying to figure out is how good this feature is or how well it works. If I am using the 24-105 at F4 24mm, there can be some light fall-off depending on the exposure. Would the camera get rid of it completely or partially only. Any experience with that?
Correct me if I am wrong but my understanding is that since it relies on lens data for the correction, then it only corrects light fall-off and not actual vignetting from let's say a lens hood or filter? Am I right?
I'll try this in a different forum too to see if I am lucky.
THanks a lot.
