I purchased this for a client and a handful of jobs.  I do not have any use for it moving forward so I would like to find it a new home.

Includes:

200DL Housing for GH5s
8" Dome Port with neoprene cover
Port Extension 42mm - 75042
lens ring - 5509.71
lens ring - 5509.28
Novus scratch remover and dome shine

The Ikelite 200DL Underwater Housing for Select Panasonic Cameras is a full-featured and durable waterproof housing for Panasonic Lumix GH5, GH5S, and GH5 II mirrorless Micro Four Thirds cameras. It is suitable for scuba, snorkel, surf, pool, and other applications in or around the water. Use of this housing requires a separately purchased lens port.

Construction Details
  • Depth rating of 200'
  • Made in the USA from a corrosion-resistant polycarbonate-ABS plastic blend
  • Open-groove design suspends rear O-ring in a natural position, allowing for easier maintenance and preventing accidental twisting or stretching of the O-ring
  • Camera mounting plate enables quick installation and does not need to be removed for you to gain battery or memory card access
Strobe Connection and Operation
  • Ikelite ICS-5 bulkhead connector with manual hot shoe connection enables reliable electrical triggering of optional, external strobes
  • Using optional #46032 TTL circuit and hot shoe will allow for TTL operation with compatible Ikelite DS strobes; non-Ikelite strobes will still work in manual mode only
Controls and Handling
  • Ergonomic mechanical controls, including push buttons, knurled knobs/dials, and levers
  • Extra-large, soft-touch zoom knob works with universal zoom gear system
  • Control symbols are laser-etched into the back of the housing so they won't fade or rub off over time
  • Supplied aluminum tray with a left-hand quick release grip affords improved balance and handling while offering an attachment point for an optional lighting arm
  • Slight positive buoyancy in fresh water (precise buoyancy varies depending on choice of lens and port)
Lens Port System
  • Ships without a required lens port
  • Accepts all Ikelite Dry Lock (DL) series domes and flat ports for a broad array of zoom, macro, and wide-angle lenses
  • Vacuum valve for checking watertight integrity before diving
  • Pump required to remove excess air and actually create a vacuum
