Before I decided to buy this camera, I have of course informed me very well over the Internet, and also compared to the more expensive cameras like GoPro Hero 3 and 4 and Actionpro X7. As for sharpness in sjcam sj4000, I personally see no difference to the much more expensive models. The colors are for me - in previously properly selected and adjusted white balance - even more natural. Who does not need a 4K resolution and no special attention to particularly effective slow motion sets, which is well served with this camera. There are in this Actioncam much accessories and just a WiFi function and APP (which awarded the remaining works) as for the expensive cameras.
