The catch
Panasonic LUMIX S1II body
No backup is possible for formats SD cannot take or in specified proxy and loop modes. The 5.1K60 portrait crop falls below native portrait 4K.
Side by side
Panasonic S1II vs Nikon Z6III: S1II holds on to supported video copies, Z6III captures 6K RAW at 60p
Quick verdict
Supported video copies stay with the S1II, and the Z6III records 6K RAW at 60p. Take the S1II for eligible duplicate video, or for 5.1K 3:2 at 60p when two orientations matter. Take the Z6III if internal 6K N-RAW at 60p and compatible Nikon lenses fit the work. Video on the Nikon goes to one selected card. Both are body-only, and the advanced modes on either call for suitable media and editing support.
Before you buy
Why, and what it costs you
The body with two slots may still put the video on one card
Eligible video can be duplicated by S1II to its Type B and SDXC cards, whereas Z6III records internal video to one selected card. For an interview or family ceremony that cannot be repeated, Panasonic therefore offers a supported second recording copy, the kind Nikon’s slot count alone might seem to promise. S1II loses that advantage in formats the SD side cannot record and in specified proxy or loop settings. Pick a supported format on purpose and check both cards. Neither system protects you if the whole camera is lost, so separate verified copies stay part of the routine.
Where this comes from
Based on the explicit destination and Backup Rec documentation, exclusions included. It does not assume every mode duplicates or offer absolute data protection.
The catch
Nikon Z6III body
Internal video goes to a single card rather than two copies at once. N-RAW calls for compatible editing software.
Panasonic LUMIX S1II body
- Why pick it
- A supported video format has to be copied to two cards during the take.
- A tall 5.1K 3:2 source at 60p lets you make slow-motion edits in horizontal and in 1080 portrait.

- No backup is possible for formats SD cannot take or in specified proxy and loop modes. The 5.1K60 portrait crop falls below native portrait 4K.
Nikon Z6III body
- Why pick it
- Internal 6K N-RAW at 60p works with your editor and the Nikon lens setup you have.
- A compatible Z-mount kit and a body 40g lighter count for more to you than the tall-source option.

What this page compares
Panasonic S1II vs Nikon Z6III for important events and hybrid editing. Look at video backup, tall 60p, RAW frame rate and the lenses that stand behind the purchase.
These current full-frame hybrids compete with mixed Type B/SD slots and advanced internal recording. Similar hardware lists hide different decisions about backup and recording shape.

How we worked this out
Based on the explicit destination and Backup Rec documentation, exclusions included. It does not assume every mode duplicates or offer absolute data protection.
Different editing problems are solved by tall 60p and by 6K RAW 60
With 5088×3392 3:2 at 60p, S1II is useful when one take has to feed horizontal and portrait edits with slower playback. A full-height portrait crop of it is 1908×3392, enough for 1080 portrait output but short of native portrait 4K. Z6III’s 6K N-RAW 60 is 6048×3402 in 16:9. It can be cropped as well, but it starts from a different scene shape and calls for a RAW-capable editing workflow. Do not decide on 6K versus 5.1K alone. Work out whether the job needs a taller captured scene or the specific Nikon RAW format and rate, then frame to match.
How we worked this out
Uses exact aspect ratios, rates and 3392×9/16=1908. The Nikon source being 16:9 is not a claim that it cannot make portrait edits. No comparative RAW quality is claimed.
A RAW frame rate only matters if your next editing step can make use of it
In internal 6K N-RAW, Z6III gets to 60p. S1II’s higher-resolution 5.8K ProRes RAW option tops out at 30p, and it has separate lower-resolution RAW choices. When a specific RAW workflow needs those extra temporal frames, Nikon has a concrete reason to be picked. If the family delivery is an ordinary finished clip, compatible software, media and grading time may count for more than that option. Nikon Z lenses you already own can also keep the whole kit simpler. S1II stays useful when supported duplicate video or its tall 60p source is the recurring need, and higher-resolution RAW 60 is not.
How we worked this out
Manufacturer recording-quality tables separate codecs, dimensions and rates. It does not assert that RAW is necessary for ordinary output or that editors support both equally.

Spec by spec
Where they really differ
| Spec | Panasonic LUMIX S1II body | Nikon Z6III body | In practice |
|---|---|---|---|
| Internal video copies | Eligible Backup Rec on Type B plus SDXC | One selected destination card | The main backup difference is hidden by the slot count alone. |
| Tall 60p source | 5088×3392 3:2 | 6K N-RAW 6048×3402 16:9 | Relative to its width, Panasonic captures more scene height. |
| Higher-resolution internal RAW rate | 5.8K ProRes RAW up to 30p | 6K N-RAW up to 60p | A different RAW frame-rate requirement is what Nikon serves. |
| Body with battery/card | 800g | 760g | Before lenses and accessories, Nikon is 40g lighter. |
| Native lens setup | L mount | Nikon Z | Lenses you already own that suit the body can settle the whole purchase. |
Trade-offs
What each pick costs you
With Panasonic LUMIX S1II body
- Slots are one Type B and one SD. Card recording is disabled in SSD mode, and optional audio hardware costs extra.
With Nikon Z6III body
- Match the Type B media and reader to your chosen format. You still need a separate verified copy of the video.
Change of plan
When the answer changes
Duplicate video or tall 60p resolves the job
Go with Panasonic LUMIX S1II body. The supported routes come from S1II.
You cannot do without Nikon RAW 60 and the Z kit you have
Go with Nikon Z6III body. Z6III fits that workflow.
