The catch
Panasonic LUMIX S5IIX body
A compatible external HDMI recorder is needed for RAW output. ProRes above Full HD calls for a qualified SSD, and the cards are disabled.

Panasonic S5IIX vs Canon R6 III: S5IIX stays with two SD cards, R6 III records higher-resolution RAW in the body
Quick verdict
The S5IIX holds on to two SD cards, and the R6 III records higher-resolution RAW internally. Take the S5IIX if a supported two-SD workflow or qualified direct-SSD recording suits the kit you have. Take the R6 Mark III if internal 7K RAW or its larger 7K 3:2 source removes a specific limitation. Both are body-only. SSD mode on the S5IIX disables the cards, and on the Canon, RAW and high-frame-rate movies cannot be copied identically inside the camera.
Before you buy
Why, and what it costs you
Internal RAW cuts the gear you carry, though not the need for a second copy
RAW leaves S5IIX over HDMI and goes to a compatible external recorder, while R6 Mark III can record 7K RAW internally onto suitable CFexpress media. Someone shooting alone and moving between rooms may prefer Canon if dropping the recorder mounting, a cable and an extra powered device fixes a real setup problem. Canon’s RAW mode, however, cannot make two identical internal card copies. Less hardware does not mean the original is backed up automatically. Panasonic’s internal ProRes-to-SSD workflow produces a different file type and should not be called internal RAW. Choose the actual file and copy routine your editor needs.
Where this comes from
Separates explicit RAW output from internal RAW, and notes Canon’s media and duplication restriction and the Panasonic ProRes distinction. No universal recorder or software compatibility claim.
The catch
Canon EOS R6 Mark III body
Slots are one Type B CFexpress and one SD. Duplication is restricted for RAW and high-frame-rate recording, and full functions require LP-E6P.
Panasonic LUMIX S5IIX body
- Why pick it
- The two suitable SD cards you already own have to stay as your supported duplicate-recording setup.
- A compatible SSD handoff helps you, and the power, mounting and separate-copy steps that come with it are acceptable.
- The catch
- A compatible external HDMI recorder is needed for RAW output. ProRes above Full HD calls for a qualified SSD, and the cards are disabled.
Canon EOS R6 Mark III body
- Why pick it
- In your chosen workflow, internal 7K RAW takes the place of a compatible external RAW recorder.
- You need a larger ordinary-speed 3:2 source or 32.5MP stills, and you have suitable lenses and media.

What this page compares
Panasonic S5IIX vs Canon R6 Mark III for a video kit that keeps growing. Weigh SD backup, internal RAW, portrait crop room and what has to sit beside the camera.
A video-focused L-mount body and a current higher-resolution Canon hybrid, which a creator might cross-shop while building a more capable kit. Recording media and external equipment mark a real dividing line in the decision.

Separates explicit RAW output from internal RAW, and notes Canon’s media and duplication restriction and the Panasonic ProRes distinction. No universal recorder or software compatibility claim.
Sticking with a pair of SD cards you know can make the better event setup
Two appropriate SD cards can take eligible backup recordings on S5IIX. Canon’s first slot is CFexpress Type B, so two SD cards you already own cannot fill both slots. When ordinary supported footage already satisfies the delivery requirement, Panasonic lets you keep the familiar card and reader routine, instead of changing formats just because the body is newer. SSD mode has to 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 get copied after the shoot.
How we worked this out
Covers card formats and the documented backup and SSD exclusions. It gives no current accessory prices and no universal duplication promise.
The larger portrait crop is worth most when you cannot restage the subject
A full-height 9:16 crop of Canon’s 6912×4608 3:2 source at ordinary speed leaves 2592×4608, while S5IIX’s 5952×3968 leaves 2232×3968. Each is above 2160×3840 before any additional crop, but Canon gives you more room to reposition or trim and still hold that output size. That can help when a one-time performance has to yield both a wide family film and a portrait version. It will not automatically keep a moving person who is off center inside the portrait frame. S5IIX may already do the job if the framing is planned and the smaller crop meets the output.
How we worked this out
4608×9/16=2592 and 3968×9/16=2232, using the 3:2 modes up to 30p. No stabilization or lens-correction crop is assumed.

Where they really differ
| Spec | Panasonic LUMIX S5IIX body | Canon EOS R6 Mark III body | In practice |
|---|---|---|---|
| Two-card arrangement | Two UHS-II SD | Type B CFexpress plus SD | For eligible duplication, an existing SD pair favors Panasonic. |

| Tall ordinary-speed source | 5952×3968 up to 30p | 6912×4608 up to 29.97p | For two orientations, Canon has more pixels to crop from. |
| SSD recording and copies | Qualified USB SSD, cards disabled | Internal card-based RAW route | Settle where the original file is stored first, then plan your backups. |

Trade-offs
What each pick costs you
With Panasonic LUMIX S5IIX body
- The drive or recorder is a separate item. Ordinary SD recording is still available and needs no SSD rig.
With Canon EOS R6 Mark III body
- Set aside money for media, a reader and compatible power. Wi-Fi and other functions can be restricted by older Canon batteries and BG-R10.
Change of plan
When the answer changes
Your current SD or L-mount recording setup does the job
Go with Panasonic LUMIX S5IIX body. S5IIX keeps that equipment in use, within explicit mode limits.
A limitation you keep hitting goes away with internal RAW or more crop room
Go with Canon EOS R6 Mark III body. With the right media, Canon delivers those outputs.
Decision guide
Before you buy
You want editing to be easier and cropping to have more room, without replacing every card or adding a drive to every take.
