Light & Motion Titan D100 Housing

A little over a year ago, I wrote a review for Wetpixel of the Light & Motion Titan housing for the Olympus E20. At the time, this was one of the few SLR cameras available and had a “whopping” 5 megapixels. As usual Light & Motion was first out of the blocks with an innovative housing for this camera and introduced the revolutionary ROC strobe control system. (This strobe control system was subsequently incorporated into their Tetra Housings for the Nikon Coolpix and the Olympus 5050, and now the 5060, cameras.

With experience comes perfection, and while an excellent housing, the Titan E20 had some reliability problems found in many newly introduced products. With the introduction of the Nikon D100, digital photography has taken a quantum leap. Underwater photography has also taken that leap with the introduction of the Light & Motion Titan D100 housing.

Light & Motion introduced the new Titan D100 at DEMA 2002 and it began shipping this past summer. I finally was able to give one a serious go for 2 weeks this past August while I was conducting one of my digital workshops aboard the Kona Aggressor and again for 2 weeks just recently during a Cayman Aggressor workshop.

It’s one thing to go out diving for a few days of housing testing, but after doing as many as 5 dives per day, everyday for 4 weeks, I was able to work every feature of this housing and then some.

Left Handle
         Right Handle

As usual, Light & Motion has delivered a work of design art. Ergonomically efficient, it has both manual and electronic controls. The rear panel includes all available manual controls as well as the ROC ( Remote Optical Controller ) display. The ROC controls, as well as the Main Dial (Aperture) control, the Sub Dial (shutter), and Auto Focus control are located on the left and right handles (it’s possible to swap the Main and Sub dial functions if you choose). Unlike manually operated housings, the Titan D100 allows total control of shutter, aperture, auto focus, and strobe power remotely from these handles. For most situations, it is not necessary to move your hands from the controls.


The ROC System


With the E20 housing, Light & Motion introduced their revolutionary ROC strobe control system. That system, which allows the user to obtain up to 12 manual power levels on most TTL compatible strobes, migrated to the Tetra 5050 and the Tetra Coolpix 5000 housings. It is also the one of the main features of the new Titan D100, but with some serious improvements.

With the Titan E20, I had always felt that the placement of the electronics was vulnerable to moisture or some other type of damage. With the Titan D100, Light & Motion has done a couple of things to almost eliminate these concerns.

Incredible Moisture Protection

All of the electronic contacts are specially coated to prevent moisture and even direct water damage. The main electronics board is not only fully coated but it is enclosed safely in the camera tray. There is also a moisture sensor, which will set off a “light show” on the ROC board if any moisture is detected.

Although I am embarrassed to admit it, I was able to inadvertently test this system…not once but TWICE. Yes, I flooded my Titan D100 on 2 different occasions while in Kona
(the first time I have ever flooded any type of housing). The first time it happened I was sure both my camera and housing were toast. I was so confident of the Titan’s double
o-ring system that I didn’t realize that the moisture alarm was “yelling” at me until I had descended about 20 feet. Once I realized what was happening, I ascended slowly to the Aggressor’s swim step, handed the housing up to one of the dive staff, and made a b-line for the camera table.

To make a long story short, there was about 2 inches of water in the port area (I had pointed the housing port down as soon as I realized what was happening), the camera bottom, tray and other electronics were very wet. I dried everything off and put the camera and housing in the engine room overnight to absorb all remaining moisture. The next morning, to my amazement, the camera and housing worked perfectly.

After some investigation, I figured that the leak was caused by my carelessly pinching an o-ring on the front port. So, from that point on I began to check the housing in the rinse tank prior to each dive, as well as immediately upon entering the water. It was during my second week on the Aggressor that it happened again. But this time I was ready and only a little bit of water made it into the housing. After drying everything off on the camera table, the camera and housing worked perfectly and I just went back in the water as if nothing happened. From that point on I realized that the electronics in this housing have really been perfected.

Housing Optics


As with other Light & Motion products, no expense has been spared in the development of housing optics. The most impressive feature here is an all Optical Glass 8” Dome wide angle port which supports Nikon 14mm, 16mm, 18mm, 20mm, 24mm, 17-35mm, 18-35mm, and the new 12-24mm lenses. Some lenses require an extension ring.

Also available is the Macro port that will accommodate the Nikon 60mm Macro and the 105mm Macro (with an extension ring) and Conversion Rings are available for Sea & Sea, Subal, and Aquatica ports. Zoom and focus rings are also available for supported lenses.

The lenses feature a bayonet mounting system which locks the ports and extension rings VERY securely. You definitely know when your ports locked in place preventing any possibility of leakage.

One of my favorite features: Latches


Probably one of the most overlooked features of any underwater housing is its latch system. I am of the opinion that Light & Motion makes the most user- friendly latches available. Unlike other housings that require 3 and sometimes 4 release latches, Light & Motion housings use a swivel type latch system that requires only 2 side latches. This makes it very easy to install and remove the housing back. Other latch systems I have used can be tricky when installing the back and the latch can get caught between the front and back elements of the housing, possibly damaging an o-ring.

Camera Tray System

The camera tray system is another elegant solution. The tray contains the ROC electronics, hot shoe connector, camera connection, gears for the focus mode selector, and a lever to allow lens removal when changing ports. You can easily change lenses without having to remove the camera from the housing.

The camera tray is mounted to the housing through pair of metal guides that keep the camera in exact position inside the housing. By pressing the metal release bar on the right of the camera tray, the camera and tray just pop out.

Attention to Detail


Since the Titan D100 has a number of electronic controls, it needs to communicate with the camera. On the bottom of the Nikon D100 are a series of contact pins that allow the housing to access all of the features electronically.

These pins are covered by a rubber gasket, and until I used this housing and had to remove this cover, I didn’t even know that they were there. It is necessary to remove the gasket to reveal the contact pins, and when the camera is mounted on the tray it actually plugs in.. This allows for total housing to camera communication.

Paying great attention to detail, Light & Motion designed the camera tray with a little cutout area that allows you to safely store the rubber gasket while it is off the camera. Very cool.

Wish List

There are a few things I would wish Light & Motion had done differently:

Overall Impression

The Light & Motion Titan D100 is really an impressive system. Perfectly balanced in the water; outstanding optics with ability to use your existing ports; extensive feature list including all camera controls and the upgraded ROC system, I have to say that I love this housing.
