Main trade-off
Panasonic LUMIX S5IIX body
RAW output needs a compatible external HDMI recorder. ProRes above Full HD requires a qualified SSD, with cards disabled.
Head-to-head
Panasonic S5IIX vs Canon R6 III: S5IIX keeps two SD cards, R6 III puts higher-resolution RAW inside
The short answer
S5IIX keeps two SD cards, while R6 III puts higher-resolution RAW inside. Choose S5IIX when a supported two-SD workflow or qualified direct-SSD recording fits the existing kit. Choose R6 Mark III when internal 7K RAW or its larger 7K 3:2 source removes a specific limitation. Both are body-only. S5IIX SSD mode disables cards, while Canon RAW and high-frame-rate movies cannot make identical internal copies.
Before you choose
The reasoning and the trade-offs
Internal RAW can reduce equipment, but not the need for a second copy
S5IIX sends RAW through HDMI to a compatible external recorder. R6 Mark III can record 7K RAW internally to suitable CFexpress media. A solo shooter moving between rooms may prefer Canon if removing recorder mounting, a cable and an extra powered device solves a real setup problem. Canon’s RAW mode cannot make two identical internal card copies, however. The reduced hardware does not mean the original is automatically backed up. Panasonic’s internal ProRes-to-SSD workflow is a different file type and should not be described as internal RAW. Choose the actual file and copy routine the editor needs.
What this is based on
Explicit RAW output versus internal RAW, Canon media/duplication restriction and Panasonic ProRes distinction. No universal recorder or software compatibility claim.

What matters in practice
The differences that matter
Internal RAW can reduce equipment, but not the need for a second copy
S5IIX sends RAW through HDMI to a compatible external recorder. R6 Mark III can record 7K RAW internally to suitable CFexpress media. A solo shooter moving between rooms may prefer Canon if removing recorder mounting, a cable and an extra powered device solves a real setup problem. Canon’s RAW mode cannot make two identical internal card copies, however. The reduced hardware does not mean the original is automatically backed up. Panasonic’s internal ProRes-to-SSD workflow is a different file type and should not be described as internal RAW. Choose the actual file and copy routine the editor needs.
How we reached this conclusion
Explicit RAW output versus internal RAW, Canon media/duplication restriction and Panasonic ProRes distinction. No universal recorder or software compatibility claim.
A familiar pair of SD cards can be the better event setup
S5IIX supports eligible backup recordings on two appropriate SD cards. Canon’s first slot uses CFexpress Type B, so two existing SD cards cannot fill both slots. If ordinary supported footage already meets the delivery requirement, Panasonic can retain the familiar card and reader routine rather than making a format change solely because the body is newer. SSD mode must be Off for the Panasonic card copies to work. Both cameras have mode restrictions and need enough space and speed on the required media. Compare the complete event workflow, including how files are copied after the shoot.
How we reached this conclusion
Card formats and documented backup/SSD exclusions. No current accessory prices or universal duplication promise.
The larger portrait crop matters most when the subject cannot be restaged
At ordinary speed, Canon’s 6912×4608 3:2 source leaves 2592×4608 for a full-height 9:16 crop. S5IIX’s 5952×3968 leaves 2232×3968. Both exceed 2160×3840 before any additional crop, but Canon provides more room to reposition or trim while retaining that output size. This can help when a one-time performance needs both a wide family film and a portrait version. It does not keep an off-center moving person inside the portrait frame automatically. S5IIX may already be sufficient if the framing is planned and the smaller crop meets the output.
How we reached this conclusion
4608×9/16=2592, 3968×9/16=2232. Up-to 30p3:2 modes, no stabilization or lens-correction crop assumed.

Meaningful differences
What changes the fit
| What changes | Panasonic LUMIX S5IIX body | Canon EOS R6 Mark III body | Why it matters |
|---|---|---|---|
| Two-card arrangement | Two UHS-II SD | Type B CFexpress plus SD | An existing SD pair favors Panasonic for eligible duplication. |
| RAW recording equipment | Compatible external HDMI recorder | Internal 7K RAW on suitable media | Canon can remove an external recorder from that setup. |
| Tall ordinary-speed source | 5952×3968 up to 30p | 6912×4608 up to 29.97p | Canon provides more crop pixels for two orientations. |
| SSD recording and copies | Qualified USB SSD, cards disabled | Internal card-based RAW route | Choose where the original file will live before planning backups. |
| Large stills | 6000×4000 | 6960×4640 | Canon adds 16% more pixels along each edge. |
What you give up
Every choice has a cost
If you choose Panasonic LUMIX S5IIX body
- The drive or recorder is separate. Ordinary SD recording remains available and does not require the SSD rig.
If you choose Canon EOS R6 Mark III body
- Budget media, reader and compatible power. Older Canon batteries and BG-R10 can restrict functions including Wi-Fi.
Recommendation switch
The decision flips if...
The existing SD or L-mount recording setup works
Choose Panasonic LUMIX S5IIX body. S5IIX retains that equipment with explicit mode limits.
Internal RAW or more crop room removes a repeated limitation
Choose Canon EOS R6 Mark III body. Canon provides those outputs with the right media.
What matters in practice
Before you choose
You want easier editing and more room to crop without replacing every card or adding a drive to every take.
What this comparison cannot tell you
- No measured RAW-quality or autofocus comparison.
- Pixel dimensions do not predict file sizes or computer performance.
