Ikelite 4405 High Sensitivity Optical Slave Converter for Remote Triggering of DS Strobes

Product Details

The High-Sensitivity Ikelite Optical Slave Converter is perfect for use in environments with high ambient light or large distances between your remote strobe and the primary flash.

This is a non-learning, sensor that requires the camera to be in manual flash mode. This Converter will not work with a pre-flash. The Optical Slave Converter supports manual exposure modes as set on the attached DS strobe. TTL exposure mode is not supported.

If your primary purpose is to trigger a strobe fibre optically by a compact digital camera’s flash, we recommend the Fibre Optic Converter # 4401.3 or RC1 Olympus & Panasonic TTL Receiver # 4412 instead.

High-Speed Shooting

If you’re shooting a DSLR or mirrorless camera with a Nauticam fibre optic converter and want to shoot at high frame rates (4 FPS or faster), then this Converter is the right option for you. The included fibre optic port allows the attachment of Ikelite, SEA&SEA, Olympus, and certain Nauticam fibre optic cables.

Attachment and Use

The Converter simply attaches to the Ikelite strobe’s electrical bulkhead in place of a sync cord connector. The enlarged slave window provides an approximately 90 degrees field of view for remote triggering.

An optional 3-foot Extension Cord # 45023 (3 ft / 1 m)  or # 45025 (15 ft / 5 m) may be added for more flexible positioning of the sensor window. This set-up is perfect for creative backlighting in wrecks, caves, and pool use. It can also be used above water for studio photography work.

An individual Converter is needed for each strobe. The use of multiple strobes requires one Converter per strobe. The Converter supports DS50, DS51, DS125, DS160 and DS161 strobes.

This product replaces the Optical Slave Converter # 4403.
