Canon C-Log firmware upgrade by mail
No Canon Log profile in your 5D Mark IV movie menu? It is not a fault: C-Log is a separate official upgrade that has to be installed on the individual body — a standard firmware update will never add it. We install it for a fixed €50, the day the camera reaches the lab.
What is included
- Official Canon Log upgrade installed on your body
- Verification of the C-Log profile and movie-menu settings
- Full function check of the camera included
Who it is for
- You shoot video on the 5D Mark IV and want the flat, gradable profile of the Cinema EOS range
- You bought the body second-hand and the upgrade was never installed
- You match footage from several bodies and yours grades differently
The honest total
€50 for the upgrade + €20 tracked UPS return to most EU destinations. You ship the body to us with the courier of your choice (typically €10–25 inside the EU). No customs paperwork in either direction.
Send the body with its battery charged — we need it for the installation. Remove the memory card.

C-Log upgrade — common questions
My camera gets regular firmware updates — why is C-Log still missing?
Because Canon Log for the 5D Mark IV is not part of the standard firmware: it is a separate official upgrade that must be installed on each individual camera body. Downloading firmware from Canon’s website will never enable it.
How long is the camera away in total?
The installation is done the day the camera reaches the lab (1–2 working days including verification), plus courier transit in both directions — around a week door to door for most of the EU.
Does it work on other Canon models?
This official upgrade is specific to the EOS 5D Mark IV. Many later Canon bodies ship with Canon Log already enabled — if you are unsure about your model, ask us first via the contact form.
