Digital Camera World Verdict

There are a handful of toughened digital compacts from a range of manufacturers that allow for immersion underwater and the taking of stills and videos without the need for additional housing. But the SeaLife Micro 3.0 is one of the few consumer-level underwater cameras available that can still strut its stuff at deeper depths of up to 60m, shooting 4K video and 16 megapixel stills, even if we do pay a premium price here for the pleasure.

The taking of photo and videos underwater used to require additional specialist housing for existing camera models that was cumbersome and expensive, meaning that it remained the preserve of the serious enthusiast or pro. However, over the past decade toughened consumer-targeted digital cameras that can be used at depths typically between 15 and 30 metres without additional armour have become commonplace.

 While the rise of smartphone photography has killed off most standard digital compacts, these robust models with their industrial metal screws and internally stacked zoom mechanisms have given people a reason to still buy a dedicated camera. That said, with the camera market having contracted greatly during the pandemic, even the choice here is less numerous than it once was.
