Question about Olympus PT-056 Underwater housing for TG-3 and TG-4

Yes, the PT-056 UW housing is also suitable for the TG-4, all functions can be operated. The TG-4 is compatible with the shape and button arrangement of the TG-3. Recommendation: As soon as gloves have to be worn, the camera should be placed in the housing, the operation of the TG-4 (which is sealed up to 15m) is awkward with gloves.
The TG-4 with the PT-056 is a super combo.
