A underwater GR would need different specification and design so it might not work well for both underwater and on land.
- You need to be close to the subject under water for best clarity, so the camera have to be wide angle and with good macro capabilities.
- You loose 1/3 of the FOV under water so an ultra wide or fish-eye lens might work best. A zoom lens could be better to use for both under water and on land.
- A retractable lens would might not be possible to seal for under water use, so the lens would make the camera larger. If using a zoom lens it would make the camera quite large with internal zoom and focus.
- Sealing would make the camera larger in general.
So in the end this might make the underwater GR the size of FI Sony RX10. And make it a completely different camera from the GR we have today.
