What is the difference between Canon Log, Canon Log 2 and Canon Log 3?
The original Canon Log delivers a dynamic range of approximately 12 stops, Canon Log 2 up to 16 stops, and Canon Log 3 up to 14 stops. Canon Log 2 retains more detail in darker areas than Canon Log 3 but also features an elevated noise floor. Canon Log 3 is easier to grade thanks to producing a cleaner image and retains the same amount of highlight information as Canon Log 2.
What is Canon Log used for?
Canon Log is used to capture video footage that has a wider dynamic range and exposure latitude than standard video. The Canon Log tone curve is applied at the point of capture to retain more details in the highlights and shadows compared to standard video.
Which Canon Log is best for low light?
Canon Log 2 is the ideal choice for when maximum detail is required, particularly in low-light scenes to extract shadow information. However, it will also cause elevated noise in those darker regions of the image and therefore require more time in post-production.

Which Canon DSLRs, Mirrorless, and Cinema cameras have a C-log profile not listed here?

The Canon 1DC I know had C-Log 1, yet it's not listed there (probably because it's old as hell). Not all of the specs are always clear on which cameras have C-log for video and a comprehensive list would be super useful from any of the Canon supernerds out there!
Additional question, does Magic Lantern apply log profiles to cameras that didn't have the profile before? Might wanna get an oldie but goldie and "jailbreak" it and turn in into a video beast (FF preferably).
Probably an amateur question, but reading American Cinematographer, I occasionally come across mention of "gamma function," S-log, C-log, and other logs. I was wondering what exactly these are, and what purpose they serve and so on? Thanks!
