Head-to-head
Panasonic S1II vs Nikon Z6III: S1II keeps supported video copies, Z6III records 6K RAW at 60p
The short answer
S1II keeps supported video copies, while Z6III records 6K RAW at 60p. Choose S1II for eligible duplicate video or 5.1K 3:2 at 60p when two orientations matter. Choose Z6III when internal 6K N-RAW at 60p and compatible Nikon lenses serve the work. Nikon video goes to one selected card. Both are body-only, and advanced modes on either need appropriate media and editing support.
Before you choose
The reasoning and the trade-offs
The two-slot body may still leave the video on one card
S1II can duplicate eligible video to its Type B and SDXC cards, while Z6III records internal video to one selected card. For an interview or family ceremony that cannot be repeated, Panasonic can therefore provide a supported second recording copy that Nikon’s slot count alone might seem to promise. S1II’s advantage disappears in formats the SD side cannot record and in specified proxy or loop settings. Choose a supported format deliberately and check both cards. Neither system protects against losing the entire camera, so separate verified copies remain part of the routine.
What this is based on
Explicit destination and Backup Rec documentation with exclusions. No assumption every mode duplicates or absolute data protection.
Main trade-off
Nikon Z6III body
Internal video records to one card, not two simultaneous copies. N-RAW needs compatible editing software.
Panasonic LUMIX S1II body
- Choose it for
- A supported video format must have two card copies during the take.
- A tall 5.1K 3:2 source at 60p helps make horizontal and 1080 portrait slow-motion edits.
- Main trade-off
- Backup is unavailable for formats incompatible with SD and specified proxy/loop modes. 5.1K60 portrait crop is below native portrait 4K.
Nikon Z6III body
- Choose it for
- Internal 6K N-RAW at 60p fits your editor and the existing Nikon lens setup.
- A compatible Z-mount kit and a body 40g lighter matter more than the tall-source option.
- Main trade-off
- Internal video records to one card, not two simultaneous copies. N-RAW needs compatible editing software.

What matters in practice
The differences that matter
The two-slot body may still leave the video on one card
S1II can duplicate eligible video to its Type B and SDXC cards, while Z6III records internal video to one selected card. For an interview or family ceremony that cannot be repeated, Panasonic can therefore provide a supported second recording copy that Nikon’s slot count alone might seem to promise. S1II’s advantage disappears in formats the SD side cannot record and in specified proxy or loop settings. Choose a supported format deliberately and check both cards. Neither system protects against losing the entire camera, so separate verified copies remain part of the routine.
How we reached this conclusion
Explicit destination and Backup Rec documentation with exclusions. No assumption every mode duplicates or absolute data protection.
Tall 60p and 6K RAW 60 solve different editing problems
S1II offers 5088×3392 3:2 at 60p, useful when the same take needs horizontal and portrait edits with slower playback. Its full-height portrait crop is 1908×3392, enough for 1080 portrait output but below native portrait 4K. Z6III’s 6K N-RAW 60 is 6048×3402 in 16:9. It can also be cropped, but begins with a different scene shape and requires a RAW-capable editing workflow. Do not choose from 6K versus 5.1K alone. Decide whether the job needs a taller captured scene or the specific Nikon RAW format and rate, then frame accordingly.
How we reached this conclusion
Exact aspect ratios, rates and 3392×9/16=1908. Nikon source is 16:9, not a claim it cannot make portrait edits. No comparative RAW quality.
RAW frame rate matters only if the next editing step can use it
Z6III reaches 60p in internal 6K N-RAW. S1II’s higher-resolution 5.8K ProRes RAW option stops at 30p, with separate lower-resolution RAW choices. If a specific RAW workflow needs those extra temporal frames, Nikon has a concrete reason to be selected. If the family delivery is an ordinary finished clip, compatible software, media and grading time may matter more than that option. Existing Nikon Z lenses can also keep the complete kit simpler. S1II remains useful when supported duplicate video or its tall 60p source is the recurring need rather than higher-resolution RAW 60.
How we reached this conclusion
Manufacturer recording-quality tables distinguish codecs, dimensions and rates. No assertion RAW is necessary for ordinary output or that editors support both equally.

Meaningful differences
What changes the fit
| What changes | Panasonic LUMIX S1II body | Nikon Z6III body | Why it matters |
|---|---|---|---|
| Internal video copies | Eligible Backup Rec on Type B plus SDXC | One selected destination card | Slot count alone hides the main backup difference. |
| Tall 60p source | 5088×3392 3:2 | 6K N-RAW 6048×3402 16:9 | Panasonic records more scene height relative to width. |
| Higher-resolution internal RAW rate | 5.8K ProRes RAW up to 30p | 6K N-RAW up to 60p | Nikon serves a different RAW frame-rate requirement. |
| Body with battery/card | 800g | 760g | Nikon saves 40g before lenses and accessories. |
| Native lens setup | L mount | Nikon Z | Existing suitable lenses can decide the complete purchase. |
What you give up
Every choice has a cost
If you choose Panasonic LUMIX S1II body
- One Type B plus one SD slot. SSD mode disables card recording and optional audio hardware adds cost.
If you choose Nikon Z6III body
- Use the right Type B media and reader for the chosen format. A separate verified video copy remains necessary.
Recommendation switch
The decision flips if...
Duplicate video or tall 60p resolves the job
Choose Panasonic LUMIX S1II body. S1II supplies the supported routes.
Nikon RAW 60 and the existing Z kit are essential
Choose Nikon Z6III body. Z6III serves that workflow.
What matters in practice
Before you choose
You want both a flexible file for editing and a second copy of a moment that cannot be repeated.
What this comparison cannot tell you
- No comparative autofocus, dynamic-range or thermal benchmark.
- Different RAW formats are not interchangeable quality scores.
