Construction Details

Depth rating of 200'
Two double-passivated, stainless steel locking latches are corrosion resistant and virtually unbreakable
Housing is made by hand in the USA from a corrosion-resistant polycarbonate and ABS plastic blend
White on the front, top, sides, and bottom to reflect sunlight and keep the camera cool when shooting on or above the water's surface
Clear in the back to allow you to monitor the O-ring seal and maintain your view of the camera's rear controls
Housing alone has nearly neutral buoyancy in fresh water, though your choice of lens and port may change the overall buoyancy of the system
Open-groove design suspends the rear O-ring in the natural position, making maintenance easier and preventing accidental twisting or stretching
Front-loading mounting plate enables quick camera installation, and does not need to be removed in order for you to gain battery or memory card access
Mounting plate has a 1/4"-20 threaded hole on the bottom for connection to an optional tripod

Strobe Connection and Operation

Use of an optional external strobe is highly recommended for color correction and adequate brightness, and basically essential once you descend deeper than 15-20' underwater
Strobe restores hues that are absorbed by the water, so your images are vibrant and accurate
Try to stay no more than 3-4' away from your subject to preserve natural colors in images
Ikelite ICS-5 bulkhead connector with a manual hot shoe connection enables reliable electrical triggering of strobes
Optional TTL hot shoe and converter, e.g., Ikelite's ST1K Sony Alpha TTL Kit, will enable TTL operation with compatible Ikelite DS strobes, which use the #4103.51 Single and #4103.52 Dual Sync Cords
Non-Ikelite strobes, such as those from Sea & Sea, INON, and Retra, will still work in manual mode only, and can be connected via #4118.1 Single and #4118.2 Dual Sync Cords
Older non-digital strobes can be used in manual mode via #4103.51 Single and #4103.52 Dual Cords
Housing ships without a required sync cord for a strobe
Bulkhead has been moved to the top of the enclosure to keep the cord out of your way and reduce strain on the ends
Ikelite's #4403 Optical Slave Converter and Aquatica's Water Wizard system are available options that will let you trigger wireless slave strobes
Exposure compensation is available via the camera's controls

Controls and Handling

Sensitive shutter and AF-On levers are curved and extendable, in order to increase comfort when using the optional right-hand grip
Push buttons have been modified to reduce weight and salt buildup
Upgraded soft-touch knobs, including the zoom knob on the side, allow for a better, more comfortable grip with or without gloves
Ergonomic, mechanical push buttons, knobs, and levers afford access to all camera functions except for the diopter adjustment dial, multi-selector, focus mode dial / lock-release button, and media slot cover switch
Control symbols are etched into the back of the housing with lasers, so they won't fade or fall off with time
Control placement is as close as possible to the layout of functions on the camera, allowing your muscle memory to guide you, so you don't have to learn another set of controls
LCD monitor can be tilted during camera installation to give you a better viewing angle
Supereye Viewfinder enhances your view through the camera's OVF when you're wearing a mask
You can remove the Supereye quickly if you'd like to attach the optional Straight or 45° Magnified Viewfinder instead
Hard-anodized aluminum tray with a left-hand quick release grip improves balance and handling, while offering an attachment point for an optional lighting arm
Optional right-hand grip can be added easily
1/4"-20 mounts and other mounting points enable connection to a tripod and the addition of accessories
Tray is more than 3/4 lb lighter than Ikelite's previous model
Housing is a 1/2 lb lighter than its FL-mount counterpart
Another 1/4"-20 threaded mount is located front and center on the housing above the port mount, allowing for the attachment of a focus light, GoPro action camera, or other lightweight piece of equipment
Spare 1/2-20 threaded port on top of the enclosure allows for the addition of various accessories
Optional Cable Grip or Aluminum Top Handle can be added for easier carrying if you're using 2 strobes

Lens Ports

Ships without a required lens port
Accepts all Ikelite Dry Lock (DL) dome and flat ports, enabling you to shoot with a wide variety of lenses
Zoom and focus gears are available for many lenses
For complete compatibility details, see the port chart linked above
DL port system accommodates lenses with large diameters
Provides added security against leaks at the surface, thanks in large part to the included vacuum valve that helps you check watertight integrity before the dive
Removal of excess air to create a vacuum requires #47011 Pump with Gauge
DL mount can be removed and replaced by the older FL (Four Lock) port locks, though this change would be irreversible unless you sent the housing back to Ikelite to have the DL mount installed again

The clear dome magnifies images to a lesser degree than a flat port does, and corrects for the underwater distortion that makes things appear 25% larger and closer--thus helping to restore a wide angle of view. Built for durability, the port is made in the USA from acrylic and acetyl plastic. Protruding edges on the top and bottom act as a built-in shade, shielding the front element from excess light to prevent glare and lens flare.
