GoPro HERO, 86 g, 4K Ultra HD, waterproof to 5 m without a case review

The dearest camera on this shelf and the lightest at 86 g, waterproof to 5 m with no case at all — a figure that reads worse than its rivals and measures something entirely different.

By Jean-Benoit Buisson

The bottom line Bought for the body and the mounts, not for the specification sheet: 86 g, sealed without a case, and fitting every bracket this maker has ever sold. The page publishes no frame rate, no stabilisation and nothing about the battery, which on the dearest camera of nine is a lot left unsaid.

On the listing

An ultra-compact design weighing 86 g, stated as 35 per cent smaller and 44 per cent lighter than the maker’s HERO12 Black; full waterproofing and ruggedness through mud, snow and water to a depth of 5 m; an intuitive touchscreen LCD for framing and switching mode by swipe; built-in mounting fingers for attaching to the maker’s own range of mounts; and a box holding the camera, a curved adhesive mount, a mounting buckle with thumb screw and a USB-C to C cable.

The depth figure is the most misread number on this shelf

Five metres, and no case. Four cameras here publish 40 m and every one of those figures belongs to a housing the camera sits inside.

Sealed without a case means nothing to latch, no gasket to pinch, no fogging, and a microphone that hears the scene instead of plastic. It also means 5 m rather than 40. For rain, mud, snow and a swimming pool the sealed body is the better arrangement; for diving it is not, and the page says 5 m plainly rather than dressing it up.

What 86 g buys

It is the lightest camera on this shelf by a third, and the mass is published — which most listings here never manage. Combined with mounting fingers moulded into the body, that is the whole argument: it goes anywhere, on anything this maker sells, and it is small enough to be carried without a decision.

What the page leaves out, and it is a lot

No frame rate for the 4K. No stabilisation claim. No battery capacity, no runtime, and no cell listed among the box contents. Eight of the nine cameras on this shelf publish at least a frame rate, and seven name stabilisation.

For the dearest camera here, those four silences are the case against it — not because the camera lacks the features, but because this page gives a buyer no way to know.

Availability

Between 197 € and 213 € on the German, French, Italian and Spanish Amazon stores when this page was last checked.

The American and British Amazon stores carry it too, priced in local currency. Those amounts are deliberately absent from the range above, which reads euro stores only.

What it does well, and what it gives up

Strengths

Waterproof without a housing, which means nothing to close, nothing to flood and nothing to fog
86 g, published, and stated as 35 per cent smaller and 44 per cent lighter than the maker’s HERO12 Black
Mounting fingers are part of the body, so it fits this maker’s enormous accessory range with no adapter

Compromises

No frame rate published for its 4K, and no stabilisation claimed anywhere
Nothing about the battery — not a capacity, not a runtime, not whether it comes out
5 m of depth on the dearest camera here, where cameras at a quarter of the price offer 40 m in a case

Specifications

Waterproof claim	5 m, and the camera itself — the second bullet calls it fully waterproof and legendarily robust through mud, snow and water, with no housing mentioned anywhere. The 40 m figures elsewhere on this shelf all belong to a supplied case, so the two numbers measure different objects
Video resolutions	4K Ultra HD, stated in the title. No other resolution is published
Frame rates	Not published on the listing — five bullets cover size and mass, ruggedness, the touchscreen, mounting and box contents, and no frame rate appears for any mode. Eight of the nine cameras here publish at least one
Stabilisation modes	Not published on the listing — no stabilisation is named, which on this maker’s cameras is ordinarily a headline feature. Nothing on the page claims it
Field of view	Not published in degrees — the page describes the camera as compact and capable without stating an angle
Mount interface	Built-in mounting fingers, stated in the fourth bullet as attaching directly to the maker’s own mounts. The box adds a curved adhesive mount, a mounting buckle and a thumb screw. It is the only integrated mounting system on this shelf
Battery life	Not published on the listing — no capacity and no runtime appears, and no spare is listed in the box
Battery removability	Not published on the listing — the box contents name no battery at all, so whether the cell can be swapped cannot be read here
Amazon reference	B0DCQYSM7W (same reference on 6 Amazon marketplaces)
EAN	0810116381869

What people ask before they commit

Why is 5 m worse than the 40 m on a cheaper camera?

It is not the same measurement. This camera is sealed in itself and goes into water as it is; the 40 m figures on this shelf are the rating of a plastic housing the camera is placed inside. A case can be taken deeper and can also be closed badly, flood or fog, and it muffles the microphone. Sealed to 5 m covers rain, mud, snow and swimming; a case covers diving. Which is better depends entirely on which of those you do.

Does this camera have stabilisation?

The listing does not say so, and this page will not assume it. That is a genuine surprise on a camera from this maker, where stabilisation is normally the first thing advertised, and it means anyone relying on it should check the maker’s own documentation rather than this retail page. What the page does sell is size, mass, ruggedness and mounting.
