Frequently Asked Questions (FAQ)

Can the housing be used for photography ? Although the A7S III is designed primarily for video, the body is perfectly suited to still photography and allows flashes to be triggered via the built-in fibre-optic ports.

Is the appliance difficult to install ? No, the internal mounting plate is precise, and the wide 125 mm port allows you to mount your lens directly onto the camera body before sliding the whole assembly into the housing.

Which batteries can be used indoors ? The housing is designed to accommodate the Sony A7S III with its standard battery, but there is still room to fit certain accessories, such as the Marelux MiniBatt, to extend the battery life.
