Should I upgrade from the Canon EOS 5D Mark IV to the Canon EOS R5 Mark II?
Upgrading is likely worth it. Canon's EF-EOS R adapter gives full autofocus with EF and EF-S lenses, so your existing lenses carry over.
What you gain
- 45MP instead of 30.4MP
- faster bursts (30fps vs 7fps)
- better video (8K 60p RAW vs 4K 30p (crop))
- in-body stabilisation
- a lighter body (746g vs 890g)
- a mirrorless electronic viewfinder showing the exposure before you shoot, and modern subject-detection autofocus
- 8 years of newer processing and autofocus (2016 → 2024)
What you give up
- Nothing significant on paper
What it costs
| EOS R5 Mark II new | £4,399 |
| EOS R5 Mark II used (MPB, typical) | £3,350 |
| Your EOS 5D Mark IV trade-in (rough estimate) | ≈ £420 |
| Net cost buying used | ≈ £2,930 |
Trade-in estimates assume about two-thirds of the typical MPB resale price; real offers vary with condition and shutter count.
