The catch
Panasonic LUMIX G9II body
It weighs 59g more. The 5.8K 4:3 mode stops at 29.97p, and SSD recording rules out the card-copy plan.
Side by side
The G9II can duplicate eligible SD movies, and the OM-1 II can hold a longer configured pre-shutter window. Take the G9II if movie copies and a taller source for two edits matter. Take the OM-1 II for its supported pre-capture setup or a BLX-1 kit you already have. Neither offer includes a lens. OM movies go to one card. The G9II loses card recording when SSD recording is enabled. Restrictions on lens, focus, electronic shutter and card speed still apply.
Before you buy
If a dog abruptly breaks out of a stationary pose, the frame you want may come before you fully press the shutter. At a nominal 20fps and its maximum 99-frame setting, the OM-1 II holds about 4.95 seconds. The G9II at its maximum 1.5-second setting holds 30 pre-shutter frames at 20fps or 90 at 60fps. Packing more samples into 1.5 seconds does not bring back an earlier moment. If a late reaction is your recurring problem, go for the longer window. Pick a higher supported rate only when tighter time spacing helps. These are configured capture windows. They are not measured keeper rates. Check lens and focus restrictions, and allow for possible electronic-shutter artifacts.
Where this comes from
99/20=4.95 seconds, 30/20=1.5 and 90/60=1.5. This assumes maximum settings and nominal rates. Focus success is not guaranteed.
The catch
It weighs 59g more. The 5.8K 4:3 mode stops at 29.97p, and SSD recording rules out the card-copy plan.
The catch
Movies are written to one selected card. Faster tracking modes call for specific lenses, and the biggest burst figure may come with fixed focus.

G9II vs OM-1 Mark II for outdoor pets, family events and one-take video edits. Weigh pre-capture timing, card copies and the work waiting after the outing.
These enthusiast Micro Four Thirds bodies each have stabilization, two SD slots and pre-capture aimed at action. One buyer in the same lens system may want a single camera for animals outdoors and for family filming at home.
Which one fits
At the specified maximum 20fps setup, OM can hold about 4.95 seconds.
The G9II supports the specified SD Backup, while OM movies go to one card.
Up to 29.97p, the G9II offers the specified 4320-pixel-high mode.
The G9II takes BLK22 instead.
In practice
If a dog abruptly breaks out of a stationary pose, the frame you want may come before you fully press the shutter. At a nominal 20fps and its maximum 99-frame setting, the OM-1 II holds about 4.95 seconds. The G9II at its maximum 1.5-second setting holds 30 pre-shutter frames at 20fps or 90 at 60fps. Packing more samples into 1.5 seconds does not bring back an earlier moment. If a late reaction is your recurring problem, go for the longer window.

99/20=4.95 seconds, 30/20=1.5 and 90/60=1.5. This assumes maximum settings and nominal rates. Focus success is not guaranteed.
The OM-1 II duplicates supported stills but records movies to one selected card. The G9II supports Backup of eligible movies across its two SD cards, so it fits more directly if the speech is the part of the occasion you most want copied as it is captured. Use suitable cards and check the selected mode. Turning on G9II SSD recording cancels that advantage, because card recording is disabled. OM stills call for a deliberate choice as well. Dual Same 5 stops when either card fills, while Dual Same 6 carries on with the remaining card and only one copy. Neither camera completes the backup job until you make a copy away from the body and verify it.
Covers card-destination behavior, card-full choices and SSD exclusions. Duplication depends on the mode and gives no protection if the whole camera is lost.
Say relatives want a widescreen film and you want a vertical clip too. The G9II’s 5760×4320 source can give you a centered 2430×4320 portrait crop before scaling. Crop a 3840×2160 horizontal movie to the same 9:16 shape and you are left with only 1215×2160. That can still make a useful smaller clip, but without enlargement it cannot deliver a native 2160×3840 portrait file. So the G9II’s taller mode spares you a second take when you compose for both outputs. It is limited to 29.97p, and anyone who moves out of the intended crop is still lost. The pixel math shows editing room, not twice the visible detail or a measured image-quality advantage.
Height×9/16 gives 2430 and 1215. Assumes a centered crop, with no extra stabilization crop or reframing margin. The G9II maximum rate is kept.

Panasonic, DC-G9M2BODY
For an important speech you need two eligible SD movie copies and not just a single selected movie card.

OM SYSTEM, V210040BU000
For outdoor action you cannot predict, a longer configured pre-shutter window matters, and you have checked the exact lens and focus mode.
Spec by spec
| Spec | Panasonic LUMIX G9II body | OM SYSTEM OM-1 Mark II body | In practice |
|---|---|---|---|
| Configured pre-shutter timing | Up to 1.5 seconds | Up to 99 frames, rate-dependent | How much time you cover is set by the chosen mode, and not only by the maximum fps. |
| Movie destinations | Eligible dual-SD Backup | One selected card | The two-slot designs protect different kinds of files. |
| Body with battery and one card | 658g | 599g | Before the same lens, OM saves 59g. |
| Battery family | DMW-BLK22 | BLX-1 | Spare batteries you already own do not carry over. |
| Recording for two shapes | 5760×4320 at up to 29.97p | Ordinary 3840×2160 16:9 movie option | Before cropping to portrait, compare the source heights. |
Trade-offs
Change of plan
Go with Panasonic LUMIX G9II body. The G9II brings the eligible card copies and the taller movie source.
Go with OM SYSTEM OM-1 Mark II body. OM keeps those specific advantages intact.
Decision guide
You want help catching a moment that begins before you press, though the next event may call for a movie that survives a card problem and works in two shapes.
