Other features include Wi-Fi so that you can use a smartphone as a remote viewer and controller, a waterproof housing rated to 60m, 12-megapixel still capture with a configurable interval timer, and burst rates up to 30fps, along with a very wide range of mounting accessories to attach the camera to your chosen piece of sports equipment. The sensor is capable of full-resolution still captures at rates up to 30ps.
The individual sensor elements are 1.55µm and are set on a back-illuminated ceramic substrate, in 4024 columns and 3036 rows of active elements, giving a 12 MPix maximum image size. The sensor on the GoPro HERO3 is a Sony model IMX117 BSI CMOS. The unit DxO Mark tested had HD3.03.02.00 installed changes in the firmware could affect the results, and there may be future updates to our review to reflect this. The HERO3, like many modern electronic devices, is firmware controlled. These rates mean smooth slow motion, which suits the purpose of the camera: to shoot action. The lens is very wide, with a 6-element aspheric design, and the maximum diagonal angle of view is 170º.įrame rates also cover a wide range, again depending on resolution, with rates up to 240fps (for WVGA), 120fps at 720p, and up to 60fps at 1080p.
The GoPro HERO3 fulfils all of these requirements: It has 3 settings greater than 1080p, the highest being 4K Cinema the weight of the basic camera is just under 75g and it’s small, 41 x 59 x 29mm. They should also be equipped with a wide lens - the wider the better, and they should be able to shoot at high frame rates for slow motion. A decent action camera has some very specific requirements: The current default seems to be that they should produce 1080p video and that they should be light-weight so that they can be attached to a helmet, surfboard, handlebar, or some other piece of speedy equipment.
