The catch
Panasonic LUMIX S9 body
It cannot use an external flash, has one SD slot and states no splash resistance. Body only.
Side by side
Panasonic S9 vs S5II: S9 is lighter to carry with the same tall source, S5II holds on to flash and backup
Quick verdict
The S9 gives you the same tall source in a lighter body, and the S5II holds on to flash and supported backup. Take the S9 for a compact everyday setup that has no use for flash. Take the S5II if compatible external flash or eligible two-card recording copies belong to the job. Both deliver 5952×3968 3:2 video at up to 30p, and both crop 4K60. Neither offer includes a lens.
Before you buy
Why, and what it costs you
The smaller camera holds on to the source for both cuts of the family film
In 6K 3:2, each camera records 5952×3968 up to 30p. Using the full source height, a 9:16 crop comes to 2232×3968, before any further stabilization or correction. An editor therefore has room for a portrait export and can still keep a horizontal version of the same carefully framed take. S9 delivers that geometry with 254g less body weight. S5II is worth it when the connected equipment or the recording-copy plan calls for its larger body. Neither makes the tall mode 60p, and neither ensures a moving subject stays inside both final crops unless you frame it carefully.
Where this comes from
3968×9/16=2232, and 254g is 740-486. This is crop geometry only, with no tested image quality or tracking guarantee.
The catch
Panasonic LUMIX S5II body
Weighs 254g more before the lens. The view is still cropped at 4K60, and tall 6K stays a 30p mode.
Panasonic LUMIX S9 body

Panasonic LUMIX S5II body

What this page compares
Panasonic S9 vs S5II for daily family clips, indoor portraits and travel. Weigh the shared 6K source, the missing flash route and the copy you make before you get home.
These are two full-frame L-mount bodies that can record tall 6K, aimed at the same family or travel buyer. Going with the smaller one changes the accessories you can use and the recording redundancy you get, and not just how the camera looks.

The daylight camera can be the wrong setup for indoor portraits
For daytime walks, a small S9 with a compact lens can be attractive. But if that camera later has to work with a compatible external flash for indoor family portraits, S9 offers no supported way to do it. S5II does, in eligible modes, though electronic or silent shooting and other special modes switch it off. What decides this is how you plan to light the room. Full-frame sensor size alone does not settle it. Continuous lighting or available light may suit the S9 job, but those are different setups. Plan and budget the lighting method before you buy the smallest body.
How we worked this out
Rests on S9’s explicit lack of flash support and the S5II external-flash manual, including its mode restrictions. No exposure, motion-freezing or health result is promised.
A backup done in the evening comes too late to serve as the first safety copy
When a child’s performance or a relative’s visit cannot be repeated, an external drive at home protects you only once the files have reached it. With Backup Rec selected, S5II can duplicate eligible recordings to two suitable SD cards, while S9 has one slot. That makes S5II useful for relying less on a single recording card before you get home. Both cards stay in one camera and share the same theft or loss risk, so you still need separate copies later. Check capacity, speed and format on both cards, since a full or inadequate card can halt the supported backup recording.
How we worked this out
Contrasts one slot with configured Backup Rec, with explicit speed, capacity and card-format limits. The timing of the copy is an inference. It does not amount to absolute data protection.

|---|---|---|---|
| Tall video source | 5952×3968 3:2 up to 30p | 5952×3968 3:2 up to 30p | In this particular mode, S5II adds no crop pixels. |

| Recording copies | One SD slot | Two SD slots with supported Backup Rec | The documented two-card route exists only on S5II. |

Trade-offs
What each pick costs you
With Panasonic LUMIX S9 body
- Pick the lens to suit your subject. The optional tiny 26mm F8 lens is manual focus, and tracking on the body does not give it autofocus.
With Panasonic LUMIX S5II body
- The flash and a second suitable card are bought separately. Flash cannot be used in electronic or silent shooting and other restricted modes.
Change of plan
When the answer changes
Everyday carrying and ordinary-speed clips come first
Go with Panasonic LUMIX S9 body. In S9, the tall source comes in a lighter body.
What matters is lighting accessories or immediate copies
Go with Panasonic LUMIX S5II body. The broader setup is what S5II supports.
