1/8/08: New regulations limit the number of spare Lithium batteries that can be taken on airplanes. All of our rechargeable batteries are NiMH--with no Lithium content--and thus not affected by these regulations.

6/22/07: .... There are now two different Canon WD-58H Wide-Angle lenses for the GL2 / XM2 on the market. Use of the #6042 housing requires the correct WD-58H lens. See the housing webpage for photos and descriptions of the two lenses.

4/2/07: .... Olympus SP-350's flash mode must be changed for strobes to operate properly in manual power settings. Correct camera settings for external strobe use explained here.

10/14/06: .... Use of Nikonos Strobes with current dSLR housings requires a special two-conductor sync cord to isolate the Nikonos ready light voltage, preventing auto firing of the strobe.

8/15/06: .... Depth limit of early 8" dome ports announced and the availability of new body with 200 foot capabilities..

11/05/05: .... Hot shoe and iTTL issues with Nikon and Olympus explained here.

10/24/05: .... #4103.51 and #4103.52 Digital Sync Cords are identified by a blue band, and MUST be used with most of the new TTL systems. Older 4-conductor sync cords look similar, but can not power the TTL circuitry included in the housings.

4/15/04: .... Revised mode and zoom gears with associated shafts for early #6807 Nikon D-70 housing and explanation of precautions available here.

11/15/04: .... The new digital SLR cameras from Nikon and Canon require a special sync cord only if used with housings from other manufacturers. This cord allows our SubStrobes to operate in manual mode and also provide fractional powers. Conversion circuitry for TTL operation is now available in Ikelite housings for some Canon and Olympus models, and we are working on iTTL for Nikon.

3/15/02: .... Old E/O sync cords will require modification to operate with our new DS-50 and DS-125 digital SubStrobes.

8/01/01: .... Erroneous instructions have been published stating that the flash meter should be set on 1/500th of a second shutter speed to eliminate available light in the measurement while testing a strobe. Wrong! This does not allow enough time for the very powerful underwater strobes to reach peak intensity, yielding a reading that is off at least one f/stop.

6/01/01: .... Modification is required to use older SubStrobes with a Nikon F5, Nikon F100, most Nikon Coolpix and Olympus digital cameras. SubStrobes produced after June 1, 2001 include this modification. Click here for information.

2/12/98 on all of our sync cord "O" rings:

We have reported a problem that some lubricants may cause the "O" ring on our sync cord connectors to soften and swell to the point that waterproof insertion is impossible. This same phenomenon can occur with SLR Port and strobe battery door "O" rings.
