My thought, that's almost deceitful of digitec :-(

Not for me in any case

The camera is waterproof up to 18 metres without a housing. With a special housing, it can be submerged up to 60 metres.

The battery of the DJI Osmo Action 4 lasts up to 160 minutes, depending on the recording settings and environmental conditions. At temperatures as low as -20°C, the camera can also record for up to 150 minutes.

The camera can be mounted on a tripod with a standard screw thread system using appropriate accessories. For example, the Adventure combo includes an extension with a 1/4"-20 thread, allowing it to be attached to a standard tripod. Additional accessories such as cages or adapters can also be used to facilitate this attachment.

it's great at night.

According to our information, no memory card is included with the Osmo Action 4 camera.

You also need the rucksack holder. I bought the carrying straps straight away, so I can use it anywhere.

I don't use it as most of my videos are on motorcycles, so it would never be fast enough. But google search points out it does have it. Have a look.

I think you'll find the answer to your question by searching for "DJI Osmo Action 3 vs DJI Osmo Action 4" on YouTube. I can tell you though that the price of the Action 4 should come down soon, as the 5 is about to be released 😉

Unfortunately no carrying case included. But it's pretty tough and I now know that I only need one battery for day trips. I just plug it in like that.

-No the cam does not have built-in GPS -Yes drag&drop -The videos are in MP4 (H.264/HEVC) -Photos in Jpeg/RAW -Sound is ok for a few words but not as good as an external microphone

Hello ! I'm not sure you'll be able to attach it to the inside of a motorbike helmet, but I'd recommend the DJI Mic 2 Bluetooth microphone (on sale at Digitec). That way you won't need a cable, and your camera will remain waterproof! Have a good trip!

Unfortunately not...

Yes, depending on the video quality and battery life settings and the size of the memory card.

Not really, it comes with a clip that is partly magnetic and has clamps to attach the Action Cam bombproof. The magnet is more for fixing and not as a magnetic holder.

This is all stated in the item description and can also be seen in the pictures. Scope of delivery 1x battery, locking screw, warranty card, lens hood, liability holder, quick guide, quick-release adapter holder, protective frame, USB-C to USB-C PD cable

I haven't tried filming at night in the streets, but it's clearly not made for that. I filmed during a visit to a cave, and the result wasn't great - it didn't manage to focus very well. However, outside during the day, it's really great.

Hi, yes I do but later. Need to gain some more experience with it.
