Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Water-resistant and dust-proof
The Luna 360 is waterproof up to 1 meter. It is also completely dust-proof as it is IP67/68 protected.
Pro Videos and photos capture lots of detail
Luna has two 4K sensors, each with 190° lenses. When their images are combined, it allows for the device to take 2k photos and 1080p videos.
Pro Vibration reduction for steady shots
The gyro stabilization that is built into the camera allows for users to get steady shots, regardless of any vibration sent through the phone.
Pro Auto-stitching from two 190° lenses.
There is no need for computing power to make 360° images or videos as the internal software stitches the two images together to reproduce a 360° video or image.
Pro Small and portable
Luna is 6 cm in diameter, making it a small device that can easily be stored or pocketed. This implies that the user can carry the device around with them hassle-free.
Pro Supports streaming over 802.11n WiFi
Users can stream the video they are recording over WiFi. This enables one to easily view recordings live.
Pro Supports Flat, Sphere, VR, and Planet viewing modes
Through the use of the free app, users can change their camera viewing modes. This makes for a more versatile experience, depending on what the user wishes to record and how they want to achieve it.
Pro Magnet connector is extremely useful
The magnet connector allows users to stick their camera to a wide variety of metal surfaces, which is not only convenient but allows for a very versatile mounting experience.
Pro Reasonably priced
At $120, this camera is much cheaper than similar models.
Pro Waterproof case (30 m)
The camera is water resistant at depths of up to 30 meters due to its waterproof housing.
Pro Substantial battery life
The 1000mAh battery lasts for about two hours while shooting 1440p30. Charging the device then takes two hours.
Cons
Con Not yet released
It appears that the item is still a pre-order and that shipments will not go out until October 2016. This is worrisome as other cameras in the past have failed to deliver, which means it may be best to wait until an official release.
Con Field of view isn't correct
The camera lens is only 190x360 degrees (instead of the 220x360 claimed) and only 180x360 degrees can be viewed without distortion. This is from an in-depth review of the Amkov_AMK100S by Jan-Markus Rupprecht, which you can find here.
Con 4:3 square format leaves large black areas
Videos are 1920 x 1440 pixels and include large black areas around the circular image. Even below the circular viewing area, there are unused black areas. The effective image area is therefore only about 1.5 megapixels in videos and in photos it is around 4.5 megapixels.
Con Control LEDs on the camera not visible to user
The LEDs have a white-translucent plastic front and appear simply white in daylight, whether they are lit or not. However, the silicone sleeve shades the LEDs, usually allowing for no direct sunlight to fall on it. In addition, the viewing opening is limited only to a few degrees, so you often cannot tell whether the camera is running or not. In this case, the user must rely on the smartphone app.
Con No additional (removable) protective cover over the actual glass lens
Since the lens protrudes from the housing, you should be extremely careful during transport so not to damage the lens.
Con Watch-type remote control not available separately
While the watch remote and camera are available for purchase as a bundle on eBay (their own store), the watch remote can not currently be purchased separately.
