The first impression is very positive. The case makes a high impression. All camera functions can be operated. Tragerieme and silicone gel for the sealing ring are also connected to this case. The UW capability has yet to prove itself first.
Update after 9 months and 25 TG.
The UW-housing is completely sealed. Even at depths greater than 40m. We recommend color filter. This has nothing to do with the case.
