Price = $2000

Camera housing - Sea & Sea  RDX100 for canon SL1 (100D) 

Port - Sea & Sea Flat Port (see system chart for RDX housing online)

Port Cover - Sea & Sea Neoprene

Strobe Converter - Sea & Sea-Optical YS Converter for RDX Housing (have a look at videos online)


This has been used for 10 dives is in great condition with only a few scratches on port.  This whole setup was nearly $3k


Setup is based in BC, Canada.  Any shipping costs I would need an address to check costs




Further details


RDX100 Housing

·         Two Fiber-optic cable sockets. By inserting the Fiber-optic Cable into the housing connector, an external strobe will be optically connected to the camera’s built-in flash enabling full-featured strobe photography and creative lighting expression.

·         Features a Optical Viewfinder 0.5x that makes it easy to see the whole field of view. An optional exchangeable viewfinder can be selected as well.

·         Various ports including NX ports can be mounted with the RDX Port Base L or the RDX Port Base S in order to accommodate many kinds of lenses.

·         Easily operated shutter lever, excellent for quick snapshots. The shutter lever can be operated in two ways – pushing from the top or pulling from the front – and offers a smooth halfway press for adjusting the autofocus so you need not worry about any missed chances.

·         Large buckle structure (with lock function). Makes it easier to open and close the back cover than existing (metal) locking latches.

·         By attaching an SA8, a SEA ARM 7 Compact or a similar arm set to the tripod socket at the bottom of the housing, up to two external strobes can be mounted.

·         When using the optional Grip-Stay L II, you can hold the camera firmly with both hands just as you can with conventional housings.

·         Strong and durable build, with a depth rating of up to 60m / 200ft.





Sea & Sea Optical YS Coverter


Optical YS Converter/C can be built into the housing

Compatible with new Optical YS Converter/C1 for RDX housing which converts the camera’s TTL


Key Benefits


Optical – No Need for Sync Cords

Sea & Sea’s Optical YS Converter converts the electronic TTL signal into a light signal. This is good for two reasons. First, photographers can use fiber optic cables instead of sync cords. These are smaller, more reliable, cheaper, easier to maintain and will not flood (sync cords can flood at strobe or housing bulkhead end and require daily o-ring maintenance).

The second benefit is that photographers can use fiber optic cables (light signal) without using the camera’s internal flash, since the Optical YS Converter converts the electronic signal into a light signal. Rapid firing of strobes with fiber optic cables was previously limited to the recycle time of the camera’s built-in flash, but this is no longer an issue. It was one of the key benefits to using sync cords over fiber optic cables, so I predict sync cords to disappear once all housing manufacturers start using optical converters. Divers also save camera battery life by not using the camera’s built-in flash.

Change from TTL to Manual During the Dive

Another major feature of Sea & Sea’s Optical YS Converter is the ability to switch between TTL and Manual power with the press of a button. Divers must no longer commit to TTL or manual before the dive, instead choosing their strobe power mode depending on the current situation.

Other Key Features

·         Fine-tune strobe power via EV controller on back of YS-D1, YS-01 or YS-110a strobe

·         Battery level indicator

·         Blue LED light indicates TTL mode is active. Green LED light indicates manual strobe power

·         Auto power off and easy re-activation to save battery life



·         Power:  2x AAA batteries (alkaline = 15hrs / Ni-MH = 12 hours)

·         Weight:  154g / 5.4oz

·         Housing Availability:  MDX-70D, MDX-D7100



The Sea & Sea Optical YS Converter is an optional (although highly recommended) accessory. If purchasing with a new housing, the team at Bluewater Photo can easily install it. For those adding it to their housing, installation is user-friendly, with two screws to attach the converter to the inside top of the housing.



So do you need the Optical YS Converter?  Different divers will have differing opinions, but with the accuracy of the converter and Sea & Sea’s new Fiber Optic Cable II, you’ll be kicking yourself for missing a shot you could have saved with TTL.

A great example is a light-colored school of fish that swam quickly by much closer than expected, blown out by your default “swim-around” strobe power settings. An optical TTL converter is certainly on my list to start saving for!

signal to a light signal. Both TTL and manual strobe photography is possible using a Fiber-Optic Cable II.
