The catch
OM SYSTEM OM-5 Mark II body
It takes one card and has a 20.37MP sensor. Its high-resolution option merges still exposures, and it does not give you a tall video source.
Side by side
OM SYSTEM OM-5 Mark II vs Fujifilm X-S20: OM-5 II makes the bag lighter, X-S20 leaves a family film space for two edits
Quick verdict
The OM-5 II is 73g lighter at body level, and the X-S20 records a tall 6.2K source for two edits. Take the OM-5 II for a properly rated outdoor lens kit and supported in-camera close-up work. Take the X-S20 if a planned horizontal take also needs a portrait version, or if separate headphone monitoring matters. Neither offer includes a lens, and both have one card. The Fuji’s tall mode tops out at 29.97p and turns off digital IS. The OM’s USB supply cannot prevent shutdown once its internal battery is empty.
Before you buy
Why, and what it costs you
The two-video-edit problem is not something a still-photo composite can solve
Suppose a school activity calls for a horizontal film for the TV and a portrait clip for family messages. The X-S20’s 6240×4160 source can be cropped to 2340×4160 at 9:16 using its full height. That leaves enough geometry for 2160×3840 before any extra cropping, as long as the important action was framed to fit both shapes. The larger 50MP still composite on the OM-5 II is a different feature and gives you no movie with that geometry. What Fuji offers here is an editable source for a specific delivery job. It does not promise sharper-looking video. The tall mode tops out at 29.97p and excludes digital IS, so fast motion or walking may need another plan.
Where this comes from
4160×9/16=2340, set against the desired 2160×3840 output. The source mode and its restrictions were verified. No detail or stabilization results were measured.
The catch
Fujifilm X-S20 body
It weighs 73g more before the lens. Tall 6.2K tops out at 29.97p, with no digital IS, and the optional fan is bought separately.
OM SYSTEM OM-5 Mark II body
- Why pick it
- Your outdoor stills kit is the priority, and 73g less on the body eases the bag you really carry.
- A supported in-camera focus-stacked JPEG is what you want, and you will pick a compatible lens.
- The catch
- It takes one card and has a 20.37MP sensor. Its high-resolution option merges still exposures, and it does not give you a tall video source.
Fujifilm X-S20 body
- Why pick it
- A single ordinary-speed take has to become a horizontal family film and also a portrait clip.
- You want headphone monitoring on its own connection, with USB left free for supported power.
- The catch
- It weighs 73g more before the lens. Tall 6.2K tops out at 29.97p, with no digital IS, and the optional fan is bought separately.

What this page compares
OM-5 Mark II vs Fujifilm X-S20 for outdoor family days and home video. Weigh complete lens kits, portrait editing, power limits and close-up output.
Both are compact, stabilized bodies priced around an enthusiast starter budget. The choice pits outdoor stills and a light bag against a stronger workflow for family video in two orientations.

For outdoor power, plan on a spare battery and not only a bigger bank
From a 5V1.5A USB source, the OM-5 II can cut battery drain, but it shuts off when the internal battery is empty and charges only with the power switch off. A bigger bank makes no difference. Likewise, Fuji’s supported power setting is not a guarantee of unlimited recording. Ahead of a long family occasion, test the mode, card and power arrangement you picked, and carry charged spares. In the OM outdoor kit, close the covers and fit an appropriately rated lens before relying on weather resistance. A USB cable hanging off the body and its weather rating do not add up to an all-weather powered setup.
How we worked this out
Drawn from the OM external-power FAQ and weather precautions, plus Fuji’s supported-power setting. There is no runtime comparison and no claim of absolute endurance.
A close-up hobby can make the smaller camera pull more weight once the walk is over
If you come home with flowers, craft objects or small finds, you may want a photograph with more of the subject in focus and no stacking editor to learn. The OM-5 II can merge three to eight focus positions into a JPEG when the exact lens supports it. Allow for the tighter final crop, and keep the object still. This is a different convenience from Fuji’s larger ordinary still file or its tall movie. A macro lens that fits the mount is not automatically a supported stacking lens, so check before you buy the body. The 73g body saving only counts once that actual lens and any support are added in.
How we worked this out
491-418=73g. The OM stacking lens restriction and the JPEG and crop output were verified. Nothing here says Fuji cannot take part in a separate post-processing workflow.

Trade-offs
What each pick costs you
With OM SYSTEM OM-5 Mark II body
- Pick the lens based on the weather and stacking support it has. Carry charged BLS-50 spares even if you have a power bank.
With Fujifilm X-S20 body
- Add the X-mount lens, a suitable card and the editing step. The body-only offer leaves out the FAN-001.
Change of plan
When the answer changes
Outdoor stills and finished close-ups come first
Go with OM SYSTEM OM-5 Mark II body. OM brings the smaller body and the supported in-camera stacking workflow.
Family movies in two orientations come first
Go with Fujifilm X-S20 body. That job suits Fuji’s tall source and its sound connections.
Decision guide
