Five THINGS TO LOOK FOR...

1

Waterproofing necessitates an internally zoomed lens, so don’t expect more than 5x optical zoom.

2

Don’t dwell on deep waterproof ratings: any camera here will survive a spot of snorkelling.

3

Touchscreens don’t feature on waterproof cameras: such displays won’t work underwater.

4

Look for decent ergonomics, like big rubberised gripping points and oversized buttons to use.

5

Battery life matters: a good tough camera should manage 300 shots per charge.
