The Canon EOS R6 Mark III and the Mark II are two generations of the same full-frame RF mount line, so they feel similar in the hand and use the same lenses. The question is whether the newer body adds something you will use. Confirm the exact differences on Canon’s own specification pages.
Same Line, Different Generations
Both cameras are all-rounder hybrids for photos and video. They share the RF mount, a similar overall role in the Canon lineup, and a comparable audience: enthusiasts, event and portrait shooters, and creators. A newer generation usually brings refinements rather than a complete change in character, so the best way to judge is to list what you need and see whether the older model already covers it.
What Usually Changes Between Generations
- Autofocus behavior and subject recognition.
- Video recording options and handling features.
- Ergonomics, controls and screen or viewfinder details.
- Battery, card and connectivity details.
Whether each of these changed here, and by how much, is something to read from Canon’s pages rather than assume.
A Simple Comparison Framework
| Question | If yes |
|---|---|
| Does the Mark II already do everything I need? | Keep it or buy one |
| Is there a named feature in the Mark III I will use weekly? | Choose the Mark III |
| Do I want the current model for longer support? | Lean toward the Mark III |
| Is the Mark II easier to find or fit my plans? | Lean toward the Mark II |
How to Decide
- Open Canon’s specification pages for both cameras side by side.
- Highlight each difference that touches how you shoot, and ignore the rest.
- Think about lenses and accessories, which carry over between them.
- If you already own the Mark II, ask whether a new feature solves a real problem or only sounds attractive.
- If you are buying your first full-frame body, consider both and choose based on features and availability.
A Note on Buying Timing
When a new generation arrives, the older model often stays available for a while and can be easier to find. That is not a reason to choose it on its own. Decide on features and handling first, then look at what is available where you shop, and confirm what is included in the box.
FAQ
Do the two cameras use the same lenses?
Yes. Both use the Canon RF mount, so RF lenses and adapted EF lenses work with either.
Should Mark II owners upgrade?
Only if a specific new feature addresses something that limits your work today. If the Mark II meets your needs, there is little reason to change.
The Short Version
Choose the Canon EOS R6 Mark III if its newer features match what you do and you want the current model. Choose the Mark II if it already covers your needs. Compare the two on Canon’s pages and let your own shooting decide.
