Product description

Construction Details
• • Features a depth rating of 200'
  • Close the two locking lid snaps at each side to see the o-ring form a watertight seal
  • Constructed by hand in USA from corrosion-resistant polycarbonate, which is white on the front, sides, top, and bottom, but clear in the back to allow you to monitor the O-ring seal and maintain view of camera's controls
  • Open-groove design suspends O-ring in natural position that is easier to maintain and more reliable than forcing it into a channel
  • Nearly neutral buoyancy in fresh water
  • Actual buoyancy varies depending on choice of lens and port

Strobe Connection and Operation
• • Housing provides direct electrical connection to camera's external hot shoe
  • Integrated circuitry and bulkhead sync cord connector enable TTL exposure with optional, external Ikelite DS Substrobes
  • Circuit features model-specific encoding, which has been fine-tuned to Sony's latest flash exposure protocol as of Nov 2015
  • Circuit powered by strobe, so there's no maintenance required and no batteries to change
  • Exposure compensation in TTL mode supported via camera's built-in control
  • SEA&SEA, INON, and Nikonos strobes may be used with the required sync cords in manual exposure modes only, but will still benefit from improved battery life and faster recycle times
  • Threaded bulkhead connector prevents accidental sync cord detachment during use
  • Bulkhead connection has been moved to top of housing to keep cords out of your way and reduce strain on ends

Controls and Handling
• • Ergonomic mechanical controls, including push-buttons, knurled knobs/dials, and a lever, afford access to all camera controls except for AF/MF/AEL switch lever, control wheel, and diopter adjustment dial
  • Controls are large and knurled or grooved for easy operation even when wearing diving gloves
  • Whenever possible, controls are located in same configuration as on camera to replicate muscle memory and familiarity you've developed with camera
  • Control symbols laser-engraved onto rear of housing won't peel off or fade with time
  • Compact aluminum mounting tray with 1/4"-20 mount and quick-release handle included
  • Tray offers improved balance and handle provides attachment point for optional lighting arm
  • Handle is curved slightly to fit natural curvature of hand, and is covered by soft molding for comfort
  • Tray/handle assembly can be detached easily by removing 2 screws
  • Optional second handle can be added for a second strobe or a video light

Lens Port System
• • Ships without required lens port
  • Accepts various dome and flat ports for a broad array of zoom, macro, and wide-angle lenses
  • For compatibility, see Port Chart linked above
  • Changing ports is quick and easy--just press on and snap the four locks closed
  • New soft-touch zoom knob puts a system of universal zoom gears right at your fingertips
  • Two sets of zoom gears included: one for use with most popular large-diameter zoom lenses, and a second for use with small-diameter zooms. Both are lightweight and easy to install with no modification to lens required

Camera Compatibility
• • Compatible only with Sony Alpha a7, a7R, and a7S
  • Although they are very similar, the Alpha a7 II, a7R II, and a7S II have slight differences in size and lens/control placement that make them incompatible with this housing
