OM SYSTEM PT-059 Underwater Case for TG-7 - Waterproof to 45 m

In this review the OM SYSTEM PT-059 underwater case is evaluated as a practical, well-built housing for owners of the Olympus TG-6 or OM SYSTEM TG-7 who want reliable underwater shooting without heavy, complex rigs. The bottom line: it is best for recreational divers and snorkelers who need full access to camera controls and a robust polycarbonate shell rated to 45 m; the single biggest reason to buy is the combination of depth rating and complete control over all camera functions in a compact, user-friendly package.

Key Features

• Waterproof to 45 m: The housing is rated to withstand water pressure equivalent to 45 meters depth, giving confidence for most recreational diving and serious snorkeling trips.
• Multi-coated glass: The front glass has coatings to reduce internal reflections, improving subject contrast and colour fidelity underwater.
• Internal flash support: The case lets the camera use its internal flash underwater to trigger compatible digital slave units for expanded lighting setups.
• High-quality polycarbonate construction: Durable material protects the camera from water, bumps and knocks on land while remaining lightweight for travel.
• Full control of camera functions: All TG-7 camera buttons and modes remain accessible so shooters can change settings without removing the camera from the case.

Who It's For

This case is aimed at owners of the Olympus TG-6 or OM SYSTEM TG-7 who want an easy-to-use, reliable housing for dives and shore-based underwater photography. It suits recreational divers, freedivers, snorkelers and travel photographers who need a compact solution that still gives access to the TG-7s specialized underwater modes such as underwater wide-angle, macro and microscope.

Photographers who need extreme professional-level strobes, optical dome ports for very wide lenses, or commercial saturation diving gear should look elsewhere; the PT-059 is designed for portability and straightforward use rather than complex, professional lighting systems.

Pros & Cons
