Main trade-off
Panasonic LUMIX S5II body
740g before the lens. Tall 6K 3:2 stops at 30p and 4K60 crops.
Head-to-head
S5II gives portrait edits room, while A7 IV keeps more stills crop pixels. Choose S5II when its 6K 3:2 source helps produce two video orientations. Choose A7 IV when suitable E lenses, a lighter body and larger still dimensions matter more. Both crop 4K60, so neither automatically solves a cramped room at that rate. Both offers exclude lenses.
Before you choose
For a portrait edit from one horizontal recording, S5II’s tall 6K source leaves 2232×3968 after a full-height 9:16 crop. A7 IV’s internal 4K 16:9 leaves 1215×2160. For stills, the direction reverses. A7 IV records 7008×4672 versus 6000×4000, about 16.8% more pixels along each edge. A buyer who films family events and crops distant photographs therefore has two separate resolution decisions. Choose from the output that repeatedly runs out of room. These are pixel dimensions, not proof that either camera produces better measured detail in every scene.
What this is based on
3968×9/16=2232, 2160×9/16=1215, 7008/6000=1.168. Ordinary-speed video, appropriate full-frame lenses and no extra crop assumed.
Main trade-off
740g before the lens. Tall 6K 3:2 stops at 30p and 4K60 crops.
Main trade-off
Internal 4K 16:9 leaves less vertical crop room than the Panasonic 6K 3:2 source. 4K60 also crops.


Panasonic S5II vs Sony A7 IV for a camera shared between family films and stills. Compare crop geometry, lenses, carry weight and the 4K60 room limit.
Established full-frame hybrid rivals for buyers splitting time between stills and edited video. The source shape and existing lens system create a clearer boundary than broad image-quality claims.
Winner by situation
S5II provides the taller 6K source.
A7 IV has 16.8% more pixels along each edge.
A7 IV uses the same native mount.
Both narrow the image area.
What matters in practice

S5II and A7 IV both use an APS-C or Super 35 area for 4K60. A 24mm full-frame lens therefore frames roughly like 36mm before further crop. If two people and a table barely fit at ordinary speed, selecting 60p can change the required lens or tripod position on either body. S5II’s 6K 3:2 advantage belongs to a different, up-to 30p mode. A7 IV’s higher still resolution does not change the movie area. Plan the frame rate and the room together before changing camera systems for a framing problem that both share.
24×approximately 1.5≈36mm equivalent from recording-area tables. No measured room fit or lens-correction assumption.
A7 IV is 82g lighter with battery and card, but the two bodies use different native lens mounts. If an existing E-mount zoom covers the family outings and a suitable prime covers home work, moving to S5II means solving those lens jobs again. Adapters require their own exact compatibility checks and should not be assumed to preserve every function. S5II can justify that change when the tall recording source repeatedly saves a second take or a compromised portrait crop. Otherwise A7 IV may be the simpler complete purchase, even before comparing the price of the bodies.
740-658=82g, native L versus E mount and body-only packages. No invented lens cost, adapter behavior or universal ecosystem superiority.

Panasonic, DC-S5M2BODY9
One take must become a horizontal film and a portrait clip with room to reposition the crop.

Sony, ILCE7M4/BQ
Compatible E lenses are already owned and 7008×4672 stills help the intended crop or print.
Meaningful differences
| What changes | Panasonic LUMIX S5II body | Sony Alpha 7 IV body | Why it matters |
|---|---|---|---|
| Ordinary-speed internal source | 5952×3968 3:2 up to 30p | 3840×2160 16:9 4K | S5II leaves more vertical crop room. |
| Large stills | 6000×4000 | 7008×4672 | Sony has 16.8% more pixels along each edge. |
| 4K60 image area | APS-C crop | Super 35 crop | Both narrow the same full-frame lens view. |
| Body with battery/card | 740g | 658g | A7 IV saves 82g before the lens. |
| Native lens system | L mount | Sony E | Existing lenses may outweigh either body advantage. |
