WOLFANG GA100, native 4K 30 fps, five video modes, 40 m housing review

The most complete list of video modes on this shelf — five combinations published rather than one — with an external noise-cancelling microphone and a 40 m housing at fifty euros.

By Jean-Benoit Buisson

The bottom line The widest choice of modes at this price and the best supplied audio, on a page that never says how long the camera runs. Between this and the Surfola beside it the choice is frame-rate flexibility against a published battery figure.

On the listing

Native 4K at 30 fps with 2.7K 30, 1080p 60, 1080p 30 and 720p 120 as alternatives, and 20 MP stills; an external noise-cancelling microphone with supplied accessories; EIS anti-shake with selfie, continuous and timed shooting modes; a robust housing rated to 40 m for swimming, surfing, sailing and snorkelling; WiFi app control for preview, settings and transfer; and a support address in the closing bullet.

Five modes, which is four more than the shelf average

4K 30, 2.7K 30, 1080p 60, 1080p 30, 720p 120. Published as a list, in one bullet. The cameras either side of this one give a single combination each, and the difference is real: 1080p at 60 is what makes a bicycle descent watchable, and 720p at 120 is what makes it slow down.

The word native, applied to the 4K, is the other claim worth holding on to. It says the sensor reads the frame rather than the processor enlarging a smaller one.

The figure the page forgets

No runtime. Two 1050 mAh batteries are in the title and no bullet says what either is good for. The Surfola one place down this shelf carries cells of exactly the same rating and states 90 minutes each, which is the comparison that makes this omission visible rather than ordinary.

The microphone, and what it implies

An external noise-cancelling microphone is supplied and named for loud surroundings. Like the remote on the camera below, it points at the housing: inside a sealed case the built-in microphone records the case. A maker who supplies an external one has understood how the camera will actually be used.

What is not named

The mounting pattern. Accessories are mentioned in the second bullet and never listed, so whether an existing helmet bracket fits cannot be read here.

Availability

About 50 € on the German, French, Italian and Spanish Amazon stores when this page was last checked.

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

Listed in the American Amazon catalogue with nothing on sale against the entry: the camera has a page there and no seller behind it.

Everything in this section is the figure Keepa carried on the day of the last update to this page. Availability and prices shift without notice.

What it does well, and what it gives up

Strengths

Five video mode combinations published, including 720p at 120 fps for slow motion, where most cameras here give one
Calls its 4K native, which distinguishes it from an upscaled mode and is a claim the maker can be held to
An external microphone with noise cancelling is supplied, named in the second bullet as working in loud surroundings

Compromises

No runtime figure at all, despite carrying the same 1050 mAh cells as a camera here that publishes 90 minutes for them
EIS is claimed without a stop figure or a statement of which modes keep it
No mounting standard named, and the supplied accessories are mentioned rather than listed

Specifications

Waterproof claim	40 m, in the supplied housing, described in the fourth bullet as robust and durable and named for swimming, surfing, sailing and snorkelling
Video resolutions	4K described as native, plus 2.7K, 1080p and 720p — four resolutions, stated in the first bullet. The word native is the maker’s, distinguishing it from an upscaled 4K
Frame rates	Five combinations published in the first bullet: 4K at 30 fps, 2.7K at 30, 1080p at 60, 1080p at 30 and 720p at 120. No other camera on this shelf publishes more than two
Stabilisation modes	EIS anti-shake, stated in the third bullet as improving video stability and smoothness, alongside shooting modes named as selfie, continuous and timed. No stop figure and no resolution limit is given for it
Field of view	170 degrees, stated in the title as wide angle
Mount interface	Not published as a standard — the second bullet mentions supplied accessories without listing them or naming a fitting pattern
Battery life	Not published in minutes — the title gives two 1050 mAh cells and no bullet states how long either records. The camera one place below on this shelf shares the same cell size and publishes 90 minutes for it
Battery removability	Removable, and two are supplied, stated in the title
Amazon reference	B09TQMCNY7 (same reference on 6 Amazon marketplaces)
EAN	0735940743006

What people ask before they commit

What does native 4K mean here?

The maker uses it to say the sensor reads a 4K frame rather than the camera enlarging a smaller one to 4K dimensions. It is a meaningful distinction on this shelf, where several cheap cameras publish a resolution without saying how it is produced, and it is the sort of claim that can be checked against footage. What the listing does not give is the sensor size behind it.

Is 720p at 120 fps useful?

For slow motion, yes: 120 frames a second played back at 30 gives four times slowdown, and 720p is the resolution this camera can read that fast. It is a real capability and the reason to note the five-mode list, because a single 4K 30 entry would not let you slow anything down.
