GoPro Hero4 Session squares off against competition

[MUSIC] GoPro might be the mountable camera market leader, but that doesn't mean it couldn't use some help to stave off competition. And that's where this come in. I'm Josh Goldman with CNET and this is the new Hero4 Session. It marks a change not only in shape going from that familiar rectangular box to a cube But also in overall use. Its the smallest and lightest Gopro to date and its also the first to be water proof without the housing, good down to 33 feet and 10 meters. With the square shape and no need for housing, Gopro includes these cages for mounting so you can rotate the session into position. The lower profile means instead of having to mount it like this, you're doing this. And if you can't get the angle just right, a new ball joint buckle is included too. Taking a que from the action cams that start up with the slide of a switch, this session turns on and starts recording with a single button press. A quick press starts it recording video. A longer one kicks it into 8 megapixel, time-lapse photo capture. Another press shuts it off. Several recording resolutions are available including 1080p at 60 frames per second and 720p at 100 frames per second. But with just this little screen and two buttons, you'll need to use the cameras built in wi-fi and bluetooth to change settings by connecting to a mobile device or a wireless remote, which isn't included. Also to keep it this small, the battery isn't removable. The continuous recording time is about two hours, but the idea is that because you can quickly power it on and off You'll be able to shoot just the stuff you need. Plus with the press of this button here you can quickly tag the best moments for easier editing. Another nice addition is its' duel mic system that dynamically switches from front to back to curb wind noise and has specially designed memories to clear water as fast as possible. With very good video and photo quality, at least in the daylight, the biggest rub for most people will likely be price. It's $400 in the US, $330 pounds in the UK, and $580 in Australia. You can read the full review on CNET.com, but if you can live with it's price, and what it lacks to get the size and weight down, this is a welcomed addition to GoPro's lineup.
