Ikelite Underwater Housing for Panasonic Lumix ZS50 TZ70

Before every dive, open the housing somewhere clean and dry, inspect and wipe the main o-ring and its groove, and close it with nothing trapped in the seal, because a single hair or grain of sand is enough to flood it. Confirm every latch is fully closed and that any vacuum or leak alarm reads correctly. Where you can, soak the sealed housing in a rinse tank or hang at the surface before descending, so a leak shows up before depth.

Remove the main o-ring regularly with a plastic tool rather than anything metal, which can nick the groove, and clean both the o-ring and the groove with a lint-free cloth. Apply a thin film of the silicone grease the manufacturer specifies, since grease helps the o-ring seat and slide rather than sealing by itself, and a thick coat only collects grit. Replace o-rings on the schedule in the manual, or sooner if they look flattened, cut, or dry.

A moisture alarm is a sensor inside the housing that beeps or flashes when it detects water, giving you a chance to abort the dive before the camera is ruined. Desiccant packs absorb humidity in the air sealed inside the housing, which prevents the port fogging as you descend into cooler water. Neither replaces a proper seal check, since they provide early warning and fog control rather than leak prevention.

Only as deep as its rated depth, which the manufacturer sets and publishes in the specifications, and it should never be exceeded even briefly. Depth ratings assume a housing in good condition with intact seals, so worn o-rings or a damaged port reduce the real margin. If your diving might take you deeper, choose a housing rated comfortably beyond your planned maximum depth.

Only if the housing is specifically rated for the depth you plan to dive, because many phone cases are splash- or snorkel-rated rather than scuba-rated. Touchscreens generally do not respond underwater, so a diving phone housing needs mechanical buttons or another control method. A phone's own water-resistance rating is not a substitute for a housing, and any housing still needs seal checks and o-ring care.

Soak the closed, sealed housing in fresh water and work every button and dial while it is submerged so salt does not dry inside the control shafts. Let it dry completely, especially around latches and seams, before you open it, since opening a wet housing drips water straight onto the camera. Avoid opening a housing on a wet, moving boat deck whenever you have the option to wait.

Get the housing out of the water and open it somewhere dry, then immediately remove the camera's battery and memory card, because leaving a battery in a wet camera does more damage than the water itself. Do not power the camera on to check whether it still works. Dry everything gently away from direct heat, get salt-water-exposed equipment to a repair technician promptly, and inspect the housing to find which seal failed before you dive it again.

This Ikelite housing (SKU 6170.50) fits the Panasonic Lumix ZS50 and the Panasonic Lumix TZ70 digital cameras. It is built specifically for these two camera models and provides mechanical access to virtually all of their controls, with the exception of diopter adjustment and the LVF-Fn2 button.

Yes. The housing's 3.9-inch diameter port accepts color filter, wide angle, and macro accessories sized for that port. It also supports the optional Ikelite AF35 strobe, which triggers automatic TTL exposure by reading the camera's built-in flash, and has two ports for Ikelite-, SEA&SEA-, or Olympus-type fiber optic cords.

The housing ships with a vinyl port cover, a flash diffuser, a flash deflector, and silicone lubricant in addition to the housing itself. The included flash diffuser improves lighting quality when you use the camera's built-in flash, which is effective between 1 and 3 feet (0.3 to 0.9m) from the subject in clear conditions.

This Ikelite underwater housing carries a 2 year limited warranty from the manufacturer. The housing is designed, built, and individually tested by hand in the USA before it ships.
