Hi

I currently have a Samsung NX3000 mirrorless camera and I absolutely love it for casual travelling and event photography purposes.
2 months ago, I damaged my gopro when I was in beach (water damage due to water getting into the case )

So I have 2 options now to replace the gopro:
1. buy another action camera, or \
2. just upgrade my NX3000 by buying a Wide angle lens + waterproof housing

Requirements: waterproof (5 meters is good enough), wide angle photos, preferably with a screen, vibrant and sharp images (>= 10MP)
Use cases: water activity photography (snorkeling, kayaking, etc), group selfie at places of attraction
Budget: RM 1500

For now, here's what I think about each option:

Buying new action camera
Pros: small and light, can use monopods to capture photos from angles/places that are not possible by hand
Cons: need to buy various accessories and learn the controls, some cameras don't have a screen

Upgrading Mirrorless camera
Pros: less stuff to carry around, long battery life (I have 2 batteries for mirrorless), slightly cheaper (if compared to gopros)
Cons: need to be careful when changing lens, selfie range limited by hand length, might look silly/clumsy using it for water activities (imagine snorkeling )

Right now I'm leaning towards Upgrading. Any pros here can offer some word of advice? Thanks!

just not so familiar with underwater compacts

plus, the form factor kinda overlaps with mirrorless

hmmm

any model to recommend?
