Don’t let its size fool you. The GoPro HERO5 Session may be small, but as a camera, it’s mighty. It focuses on portability without sacrificing power: it’s only an inch and a half tall, but it records in 4K and it’s completely waterproof. While it doesn’t have the touchscreen interface that other GoPro cameras do, it’s the only GoPro that can fit in your pocket.
Also note that their newest line of cameras, the HERO3+ (plus) are only smaller in size and lighter in weight. As of now, the Black Edition for both Hero3 and Hero3+ are only a few dollars different in terms of price, so go for the plus! And now that the HERO4's are out, check the prices of previous versions as they'll be dropping slowly. Unless of course you want the newest of the new, check out their HERO4!
Now that you've considered the features of the GoPro cameras and if the price is worth the activities you will be using it for, it is time to figure out which edition you need. The White and Silvers come in only one, so you will have to purchase specific mounts/parts you will need separately (do the math, the Black Editions with the mounts you need & WiFi accessories are a financially smart to purchase instead of a cheaper cam and everything else separately if that's what you may be doing).
Are GoPro adhesive mounts reusable?
You get many of the same shooting modes you'd find on a GoPro device, such as time-lapse photos and videos and slow motion footage at 1080p at 240 fps, and there's even a Drive mode so you can use it as a dash cam when plugged into your car, automatically turning on when you start your car and off when you stop it. It's not waterproof on its own, but a dive housing is included as well as several mounts, two batteries and a charger that simultaneously powers up both packs. It also has built-in Wi-Fi so you can connect to a smartphone and use an app to control the camera and transfer your shots for sharing.
