I don't own a camera, and usually take pictures on my iphone 6S (which I'm quite happy with), but I'd like to get a cheap waterproof camera to take on my holiday as we'll be visiting waterfalls and going white water rafting. The camera isn't so much about taking pictures under water, but rather about it being okay if it gets wet. I really don't want to spend much more than £50 as I'm on a tight budget at the moment.
I know there are a lot of Go Pro clones out there, but I'm not sure if they are any good? What's a reasonable camera for less than £50. Would the picture quality be similar to my phone?
