Built for the water and made for the Sony RX100 III, IV, V, VI and VII. Salted Line housings are hybrid housings for underwater and surf photography, rated to 60 m (195 ft) with the standard port, tough enough to take big waves and shore breaks, and small enough to travel with. 

Every control you need is within reach: the mode dial, control ring and control wheel, the zoom lever, the video record, Fn and MENU buttons, and playback. A double-sided metal hinge lock holds the case shut, a built-in leak sensor and a vacuum test port let you confirm the seal before you get in, and dual fiber-optic ports are ready for strobes. Two 1/4"-20 threads and a reinforced metal bottom plate take trays and arms, and the detachable two-stage shutter grip fits when you want one.

Every housing comes with the 4″ Medium optical glass flat port fitted, so it is ready to dive out of the box. Buy it on its own, or as a kit with a port. The 67 mm-thread macro ports add close-up, macro and wide-angle wet lenses — the short port for the RX100 III, IV and V, the medium port for the VI and VII. For wide angle, choose the  V6 dome in 6″ or 8″, acrylic or optical glass, including shade-free Surf Editions for big waves. The 80 mm bayonet takes them all. Ports carry their own depth ratings: the acrylic domes, the 8″ glass dome are rated to 40 m (130 ft).

In the box with every housing: a sun glare hood, a spare O-ring set, silicone grease, aperture control rings for the RX100 III–V and the VI/VII, and a replacement control wheel for the RX100 III.

Available in black, orange and white. Not suitable for the original RX100 or the RX100 II.
