So, I've been looking a long time for a review or videos of the new Rollei 5s, but unfortunately has not yet been found for so long in the market and no good. Now you have ordered on suspicion, and I have flirted with the GoPro Hero 3 Black Edition. Now I do sometimes fast a first for a test day Rezesion because Christmas is coming. At first I even suspect that in the Rollei the same image chip is installed as in the GoPro Hero 3 Black Edition, since the chip as well as with the GoPro definitely dissolve with 12 million pixels (14 million interpolated), which is also in the manual is! The first test is but really convincing. Shooting in low or artificial light are really great. Operation via the small screen and also sufficient in German convertible. The accessories is extensive: Various holders (head, clamping, etc.) and the great thing: the camera and the underwater housing is a tripod socket. The camera can with the screen (a battery is in the camera), and also held screen with the included spare battery pack (is so large that the screen-top) are operated in the underwater housing. Those who want a little smaller, omits both changes and the rear cap of the waterproof case against a minor (also supplied). In addition, remote control, USB cable, mini jack are on AV (connect to direct to a TV) and of course charger (mini-USB as in most MP3 players) and adhesive pads here. So as I said, I'm really happy with the times so far and would probably part with the Gopro (where lots of accessories such as battery pack, etc. still have to buy more) significantly spent more money. There is a difference to the Gopro, I do not want verscheigen: GoPro has wifi (but who really needs it?). Good 150 the Wifi is cheaper worth it? I will mainly use the Bullet for diving (maybe get it sometimes my son to skate ;-)), and then I will report my experiences. All in all 5 *****, more is not currently for the price !!!
