Image quality, while good for a small action camera, is another area where a camcorder or interchangeable lens camera will come out ahead. Mirrorless cameras and DSLRs use significantly larger imaging sensors, which capture more light and thus lead to superior image quality, particularly when you have to shoot in low light conditions. But even small-sensor camcorders benefit from built-in zoom lenses, which offer a variety of perspectives without cropping the image, as a GoPro does when selecting narrower fields of view.
Look online for GoPro videos. If you’re having trouble deciding between GoPro cameras, look online for sample videos posted by current owners. GoPro owners frequently post demo videos on various video-sharing sites, giving you an opportunity to see what video quality is like under real-world conditions. Watch as many sample videos as you can to get a sense of what each model is capable of.
To get right to the point of my writing: I can't give you a definite answer. What I can definitely tell you right now is that we are to focus on the GoPro HERO4 and HERO3+'s (and I will touch base on a few HERO2 and original 3's as well), as it is the best technology and provides options for numerous consumers. With the recent announcement of the HERO4's especially, we'll tackle the main features of those to help you decide if that hefty price is worth it.
Ensure you can easily use your camera before purchase. This is an aspect many people overlook when getting a new GoPro, and it can cost them down the line. There are many bells and whistles tied to cameras. Though they might look great, you don’t want a model you aren’t able to operate. That does not mean you have to get the simplest model out there, but you should get one that is in your comfort zone.
