Thank you for viewing. This is an underwater housing for the SONY a7sⅢ made by sea frogs. I purchased it new and used it twice. I am selling it because I don't use it often. Currently, the retail price is around 100,000 yen. It works well. Although it's for the sⅢ, it can be used with other models as well due to the button layout. (Some buttons won't function.) - Manufacturer: sea frogs / seafrogs - Model: Underwater shooting housing / Underwater housing / Waterproof case - Accessories: Sold separately - Purchase price: Approximately 100,000 yen - Specifications Waterproof depth: Professional underwater housing with a depth of up to 40m/130ft, providing reliable protection for underwater photography.
