Essential Olfi 4K HDR Action Camera

Introducing a new affordable 4K action camera from UK, Olfi 4K HDR Action Camera. This tiny camera is fitted with a Sony Exmor R Back-illuminated sensor, offering 4K UHD video recording at 24fpd and 60fps slow-motion at Full HD. If you’re thinking of shooting 120fps super-slow motion, the resolution dropped to 720fps.


Although there are several similarities between Olfi and GoPro Hero4 Black, Olfi cannot be taken lightly as well.

Olfi is very easy and straight forward to use. In fact, it only has few manual options available. It’s designed to enable you to capture those action easily while having fun. However, GoPro takes the video option to another level, which also mean you got to pay the premium for it.

Our Score:
• Excellent built and quality

• Good selection of accessories
• Unnecessary lights near buttons

What makes the camera so great is the built-in gyro stabilizer which is great when you have to mount your camera onto ant moving object like the car or your helmet.
