Main trade-off
Panasonic LUMIX G9II body
165g heavier before the lens. SSD recording disables card recording, and the taller 5.8K mode is not a 60p mode.
Head-to-head
Panasonic G9II vs Sony a6700: G9II gives two eligible copies and taller crops, a6700 keeps the E-lens kit
The short answer
G9II offers eligible movie copies and a taller source, while a6700 preserves compatible E lenses in a lighter body. Choose Panasonic for supported two-card recording or its 5.8K 4:3 editing room. Choose Sony when your E lenses and the 165g lighter body fit daily use. Both offers exclude lenses. Sony 4K120 has extra crop and no internal proxies at 120p. Panasonic’s taller mode is limited to 29.97p, and SSD recording disables its cards.
Before you choose
The reasoning and the trade-offs
A slow-motion clip and a portrait-ready take may need different settings
Both cameras can record 4K120, but that headline does not settle how you will deliver the film. A portrait crop from a 3840×2160 horizontal file leaves 1215×2160 before scaling. G9II’s separate 5760×4320 mode can leave 2430×4320, enough for a 2160×3840 portrait edit if you compose for it. That taller mode stops at 29.97p, so you must choose between that framing room and the higher-rate recording for the particular moment. Sony’s 120p mode also narrows the view. For children or pets in a small room, check the lens and recording shape before they start moving. Neither body lets the largest headline numbers happen together in one mode.
What this is based on
Source height×9/16 gives 1215 and 2430. Panasonic tall-mode rate and Sony 120p crop retained. No measured detail or autofocus claim.
Main trade-off
Sony a6700 body
One card slot. 4K120 narrows the view, needs mode-appropriate media and cannot record internal proxies at 120p.
Panasonic LUMIX G9II body
- Choose it for
- You need eligible simultaneous SD movie copies and can choose the cards and mode around that requirement.
- A single take needs a 2160×3840 portrait crop as well as a horizontal edit, using the 5.8K 4:3 mode up to 29.97p.
- Main trade-off
- 165g heavier before the lens. SSD recording disables card recording, and the taller 5.8K mode is not a 60p mode.
Sony a6700 body
- Choose it for
- You already own suitable Sony E lenses, so keeping the lens kit avoids a larger system change.
- The 165g lighter body matters to daily carry, and you accept one card plus the chosen 4K120 crop and media requirements.
- Main trade-off
- One card slot. 4K120 narrows the view, needs mode-appropriate media and cannot record internal proxies at 120p.
About this comparison
G9II vs Sony a6700 for pets, family films and everyday carry. Compare portrait edits, movie copies and the lens and card needs behind 4K slow motion.
These stabilized crop-sensor bodies compete for the same mixed stills and video buyer. Both offer 4K120, but supporting media, framing and existing lenses can make the complete purchases quite different.

What matters in practice
The differences that matter
A slow-motion clip and a portrait-ready take may need different settings

How we reached this conclusion
Source height×9/16 gives 1215 and 2430. Panasonic tall-mode rate and Sony 120p crop retained. No measured detail or autofocus claim.
A fast card cannot add the second copy the camera has no slot for
If you are the relative trusted to record an important family moment, G9II can duplicate eligible recordings to two SD cards before you reach home. Sony’s single slot cannot make that simultaneous internal copy, regardless of card speed or capacity. On Panasonic, Backup needs suitable cards and a supported mode. Recording to SSD disables the cards. On Sony, a faster card may be necessary for the selected 120p or S&Q format, but that solves recording throughput rather than redundancy. Decide separately how to capture the desired mode and when to make the first verified off-camera copy. Those are two purchases and routines that can otherwise get confused.
How we reached this conclusion
Physical slots, Panasonic Backup and SSD rules, Sony mode-dependent card requirements. No claim that expensive media eliminates failure.
The lighter camera is useful only if the rest of the kit still does the job
Sony is 165g lighter with battery and card, and retaining compatible E lenses can keep that change small. A switch to G9II requires a deliberate Micro Four Thirds lens choice instead. That matters if the current lens already frames a whole room, reaches a school sports field or stabilizes the way you normally work. Compare the actual lens combinations before calling either system more portable. For Sony slow motion, also try a sample 120p file on the editing computer because that mode cannot create an internal proxy. A smaller bag is less helpful if the files add a time-consuming conversion step every evening. G9II’s supported formats also need a tested editing workflow.
How we reached this conclusion
658-493=165g and different native mounts. Sony explicit no-proxy 120p restriction. No assumed editing speed or total-system weight.

Meaningful differences
What changes the fit
| What changes | Panasonic LUMIX G9II body | Sony a6700 body | Why it matters |
|---|---|---|---|
| Body with battery and one card | 658g | 493g | Sony saves 165g before the lens. |
| Card slots | Two UHS-II SD | One UHS-II SD | The camera can only duplicate to media it actually has. |
| Taller internal movie option used here | 5760×4320 at up to 29.97p | 3840×2160 16:9 recording | A portrait crop leaves different source dimensions. |
| 4K120 workflow | Supported mode and media required | Extra crop, no internal proxies at 120p | Check framing and editing together before the sports outing. |
| Native lens mount | Micro Four Thirds | Sony E | Existing lenses can be more consequential than the body-only gap. |
What you give up
Every choice has a cost
If you choose Panasonic LUMIX G9II body
- Both offers are body-only. Include suitable matching SD cards for eligible Backup, or a separately supported SSD rig for formats that need it.
If you choose Sony a6700 body
- Check the exact lens after the 120p crop and the V60/V90 requirement for ordinary versus S&Q recording. Test the editing computer with the selected files.
Recommendation switch
The decision flips if...
Movie copies or taller framing lead
Choose Panasonic LUMIX G9II body. G9II supplies those specific options with mode limits.
Existing E lenses and everyday carrying lead
Choose Sony a6700 body. a6700 keeps that kit smaller without changing lens systems.
What matters in practice
Before you choose
You want one camera for fast family activity and easy daily carrying, while the final videos may need both portrait and horizontal edits.
What this comparison cannot tell you
- No measured autofocus, stabilization or editing-speed ranking.
- Body weight is not complete-kit weight.
