GoPro, the action camera maker, has refreshed its entire range, including the addition of the 4k-capable Hero 3 Black Edition. The existing Hero HD and Hero 2 models have essentially been re-housed in smaller cases with updated user interfaces and will sit alongside the Black Edition as the White and Silver Editions, respectively. The Hero 3 Black Edition can shoot at up to 3840x2160 pixels at 15 frames per second. It also has 2.7k mode (2716 horizontal pixels) at 30 or 24fps, and a Protune mode that offers higher bit-rates and a neutral color profile better suited to post-processing.

The Hero 3 Silver edition, essentially a Hero 2 in the latest smaller body, also gains Protune mode for its HD output - a feature added via firmware to existing Hero 2 models. The latest models also gain Wi-Fi control to allow remote control via the recently-announced App, while the Black Edition includes a waterproof Wi-Fi controller.

The Hero 3 models have a redesigned lens, which GoPro describes as 'ultra-wide' with 'reduced distortion,' though no details of angle-of-view or whether this distorition is optically or digitally corrected are given. The smaller Hero 3 bodies house a fractionally smaller battery than previous models and use MicroSD, rather than full-size SD cards. There is also a redesigned waterproof housing with a flat lens for the new models.

The new cameras will be available in November, with the Black Edition costing around $399.
