Hawkeye Firefly just announced their latest model Firefly 8S, their first native (real) 4K action camera. Actually it is also the first native 4K action camera with optional 90° non-distortion lens. Since I received their Firefly 6S, the company became an insider tip for me. 6S was a great and low priced camera but not many people knew about it. In this article I’d like to give an overview of the new Firefly 8S and show a comparison to the earlier Firefly models.

  8. Conclusion
  9. Demo Videos & Photos

Let’s start with the first video I did. Since Firefly 6S already had a great image stabilisation, I tested Firefly 8S and compared it with Yi 4K:

 

Firefly 8S Specs

Image Sensor:
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.

Chipset:
Whereas 6S and 7S featured a Novatek chip, the new Firefly 8S offers an Ambarella A12 sensor. Again similar to SJCAM SJ7 Star or Thieye T5.

Lens:
This time from the beginning there will be 2 different versions with different lenses available. A 170° FOV model holding a F/2.8 6 glass, 170° lens. And a non-distortion 90° FOV version with a F/2.8, 11 glass, 90° lens. Notice the slightly larger lens on the right model and the slightly larger underwater case.

Video Resolution:

  • 4K – max. 30fps
  • 2.5K – max. 60fps
  • 1080p – max. 120fps (max. 60fps in Super View)
  • 720p – max. 120fps

You can switch to PAL mode for 25fps and a multiple of that. 24fps mode is not available. 30fps is actually 29.97 fps, similar to GoPro an YI Action Camera.

Image Stabilization:
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.

Recording Format:
The videos are recorded in .mp4 files, .h264 codec.

Display:
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:
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. Firefly 8S also has a rounded battery, but with a larger capacity. (The rounded edges are on the backside and therefore not visible in the image below)

Storage:
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. The remote controller of Firefly 8S looks like the one from YI.
Firefly 8S offers a mini USB port which supports an external microphone as well as A/V output!

Firefly 8S – Body, Buttons & Ports

Hawkeye Firefly 8S - 170° lens version - front- and backside

Hawkeye Firefly 8S – 170° lens version – front- and backside

On the front of Firefly 8S you will find the Power/Mode Button. Long press it to power the camera on, short press it to change between Video and Photo Mode. To enter the settings you need to press the arrow buttons on the side. What looks like a silver button on the front is actually small mirror which you can use to frame your selfies. The Firefly 8S logo is light up. When it’s blue the camera is in video mode, when it’s green, the camera is in photo mode.

On top you’ll find the shutter button that also acts as selection button when you navigate within the menu. As mentioned on one side of the camera you will find 2 arrow buttons to navigate the menu. When you press the forward button for 3 sec, you can activate wifi. On the other side there are mini USB port (which also acts as A/V output or microphone input) and a micro HDMI Port.

On the backside you’ll find the 2″ screen (640 x 480 px), the slot for your microSD card and a small play button. The button is used to enter the library or to switch between camera settings & device settings.

On the bottom you will find the battery door as well as a 1/4″ standard photo tripod thread.

 

Features & Settings

As already mention, the power button also acts as mode switch button between photo and video modes (indicated with the blue or green logo on the front). When pressing the arrow buttons on the side of the camera, you enter the menu to define which of the photo or videos modes you want to use. The selected mode is indicated with the icon on the top left of the display. The following modes are available:

Conclusion

Based on the specs Firefly 8S seems to be similar to Thieye T5, Andoer C5 and EKEN H8 Plus. In contrast to mentioned cameras Firefly 8s offers mic-in via USB, Thieye T5 has a 2,5mm port. In comparison to these cameras I think Firefly 8s has the best image stabilization. It’s even better than the higher priced YI 4K Action Camera. Similar to them EIS is not available in 4K, only YI 4K+ can do so. In the “a little over 100 USD” range to me Firefly 8S took the lead.

Great Price

Real (native) 4K recording and 1080p 120fps

 2 lens options available

Excellent Image stabilisation

 Mic-in via USB

waterproof only in case

no touch screen

no RAW photo
