The GoPro Hero 4 Black, is as mentioned above, the top of the range for the Hero 4 series and thus the most powerful of the lineup. A new processor is claimed to be twice as fast as that found in it's predecessor. The Hero 4 Black will not only have video performance enhancements, but also step up the game with far superior audio recording. There are three modes of shooting with regards to field-of-view: Narrow, Medium or Ultra Wide.
The GoPro Hero 4 Silver seems to be targeted to your average action cam user, from the weekend surfer to the seasoned hiker, or even tourist. The touch screen that is included on this model will make it easier to navigate and preview what you've taken. This is especially useful for those who want to use the photographic functions and treat it as both a still camera and video camera. The image sensor on the Silver, like the Black - allows for 12 megapixel images at 30fps.
The GoPro Hero 4 release date has officially been delayed, and that news will frustrate the hoards of extreme sports fans waiting to get their hands on the new updated camera. However, at the same time some recently revealed specs and features appear to show that the wait could be worth it, as there are some significant improvements coming in the new GoPro Hero 4.
