Firefly just announced their latest model Firefly 8S, their first real 4K action camera with electronic image stabilization. In this article I’d like to give an overview of the new camera and show a comparison to the earlier Firefly models.
Firefly 8S Specs
Firefly 8S features a 12 MP Sony IMX117 sensor, same model used in GoPro Hero4, SJCAM SJ7 Star or Thieye T5.
The earlier models Firefly 6S and 7S also featured a 12MP Sony sensor, but a different model: IMX078.
This time from the beginning there will be 2 different versions with different lenses available. A 170° FOV model and a non-distortion version with 90° lens. Notice the slightly larger lens on the right model.
- 4K – max. 30fps
- 2.5K – max. 60fps
- 1080p – max. 120fps (max. 60fps in Super View)
- 720p – max. 120fps
According to the product description the Firefly 8S will offer “Six-axis gyro video stabilization that can produce very stable video image without losing any view angle”. I’m not sure by now if the sensor is stabilized or if this is just another term for electronic image stabilization. Based on my tests with Firefly 6S the stabilization of Firefly is very good compared to others.
The videos are recorded in .mp4 files, .h264 codec.
Firefly 8S offers 2″ live view display on the backside but no data screen on the front side compared to 6S and 7S. (Resolution: 640×480).
Battery is stated with 1200 mAh. Whereas Firefly 6S used a battery with the same shape as GoPro Hero3’s battery, Firefly 7S used a battery similar to EKEN’s rounded battery. Now Firefly 8S seems to use a different new type of battery.
microSD card, up to 128 GB are supported, class 10 recommended. I recommend U3 cards for 4K resolution.
Connectivity & Ports:
The camera offers wifi to connect via App (NEW Firefly App for iOS and Android available),
and Bluetooth for a remote controller. It seems that Firefly 8S will work with the YI remote.
Firefly 8S offers a mini USB port with microphone support as well as A/V output!
Dimension & Weight:
59 x 41 x 21 mm; weight: 70g
Waterproof Case (20m water resistant), J-shaped Mount, Connectors, Bike Handlebar Mount, 360 Degree Rotation Adapter, Adhesive Mounts, Cleaning Cloth, Frame & Clip, AV Cable for FPV and manual.

Based on the specs Firefly 8S seems to be similar to Thieye T5, Andoer C5 and EKEN H8 Plus. The announcement of a “aix-axis gyro video stabilization that can produce very stable video image without losing any view angle” seems to be bold. Already Firefly 6S showed very good results in terms of image stabilization. A great and rare addition is the use of an external microphone which can’t be used with micro USB. Therefore above mentions cams don’t offer this feature. Only the SJCAM SJ7 (as well mini USB) and the newer YI 4K+ and GoPro Hero5 (USB-C port) can be used with an external mic. I’m looking forward to test Firefly 8S.
