Introducing the SJCAM SJ7 Star, one of the best and affordable true 4K action camera in 2017, equipped with the most powerful Ambarella A12S75 chipset to have a boost on its omni-directional performance. SJCAM has positioned the SJ7 Star to pit itself against the high end cameras.
To your attention, WHY do I mention a TRUE 4K action camera? A brief explanation where its resolution recorded at 3840 x 2160 pixels with 30 fps and it’s not interpolated. You can find out more information here about true/fake 4K action camera.

My humble and in depth review of SJCAM SJ7 Star at my blog

Pros
– Premium looks and features! Aluminum enclosure, gave me a solid feel and a sleek look.
– Video quality is strong, with good dynamic range and crisp details.
– Compatible with FPV
– Touchscreen!!
– Controllable with SJCAM application
– Comes with its own selfie stick and controller (not included in package)
– Voice reception is pretty clear

Cons – Gyro stabilization can only operate at 1080p 30 or 60 FPS
– Took me sometime to play with the settings. SJCAM really has a lot of features and functions to explore. I would say good and bad.
– It does not have focus function for photo taking, you gotta be real still when taking photo especially during low lights. (Anyhow, this is an action cam, not really for photo taking)


My Conclusions , The SJ7 Star is seriously a solid choice for those who wants to have a native 4K video quality but don’t want to spend twice of the price for a GoPro.
At the price $180+- , the SJ7 Star is a good performer with an economic value that has a very competitive specification as well
There are some hiccups during the testing whereby it will prompt “Low Speed Card” message (Even it is tested with a Netac Pro U3). After some findings in google, this is basically due to the firmware problem. Updated to the latest firmware and the message did not appear anymore
My 2 cents, pairing Ambarella A12S75 chipset with a Sony IMX117 sensor is a very good combination to deliver a superb good quality of video footage.
Yes, this is a good choice!
**Disclaimer : Will it be a killer of GoPro Hero5 ? Yay or Nay..? Till I have the chance to SJ7 Star Vs. GoPro 5

Hope my comments and review video will be resourceful to you. Thanks for reading!

As far as I know, SJCAM does not have any flagship store in MY but there are a couple of online sellers which they have physical shops in klang valley. You can easily obtain their info in google. Thanks
