Whether you’re still thinking of buying the Canon EOS 5D Mark III or you already own the camera, nothing beats reading the owner’s manual cover-to-cover to get a comprehensive understanding of operating the camera, camera settings, features and the available range of functionality.
Canon has officially released two Adobe PDF instruction manuals that you can download to your device or view in your browser by right-clicking or tapping the links below:
- Canon EOS 5D Mark III Instruction Manual — 28.17 MB, 404 pages.
- Canon EOS 5D Mark III Pocket Guide — 1.46 MB, 2 pages.
If the direct download links didn’t work for you, visit Canon USA’s official Brochures & Manuals page for the 5D Mark III and download from there. You’ll also find related software manuals.
The manuals are not password-protected, so you are able to print them.
There is a “Copy” watermark displayed on every page though, and you cannot copy text from the PDFs without a password, which Canon doesn’t reveal.
Information on remote control units that can be used with the 5DM3 can be found on pages 185 through 186. They are Remote Switch RS-80N3, Timer Remote Controller TC-80N3 and RC-6 Wireless Infrared (IR) Remote.
You might also want to consider third-party Canon-compatible radio-frequency (RF) wireless remote shutter solutions. Read the following articles on Phottix Cleon C8, a wireless RF (radio frequency) remote shutter release, Phottix Nikos, Phottix Cleon II and Phottix Plato to get an idea of how third-party remote switches may be useful for your requirements.
