Product Information

The Ikelite 4301.3 TTL Converter for Nikon DSLR (Version 2) is an electrical adapter that links a Nikon DSLR camera to Ikelite DS strobes through an Ikelite ICS-5 bulkhead connector, giving the camera direct control of strobe exposure in TTL mode. It features a rotating switch to toggle between TTL and manual exposure and supports one or two strobes with the correct Ikelite sync cord.

Who it is for

This converter is built for Nikon DSLR shooters running an Ikelite housing who want the camera's metering to drive strobe output instead of dialing in manual power by hand. It suits underwater photographers who shoot a wide range of subjects and need exposure to adjust automatically as distance and lighting change, while still having a quick manual override for creative control. It is designed to work with current-model Nikon DSLR and Nikon Z6/Z7 cameras paired with current-model Ikelite DS strobes.

Key details

  • Rotating switch toggles between TTL and manual exposure
  • In TTL mode, exposure compensation is adjusted through the camera's own menus
  • Connects via an Ikelite-to-Ikelite single or dual sync cord; a dual sync cord is required to run two strobes
  • Requires an Ikelite ICS-5 electrical bulkhead strobe connector and TTL hotshoe on the housing
  • Works only with Ikelite DS-series strobes, not with non-Ikelite strobes or non-DS Ikelite strobes
  • Earlier 4301, 4301.2, 4302, and 4302.2 Converters cannot be field-modified to this TTL protocol due to hardware changes
  • SKU 4301.3; the manufacturer lists this version as discontinued and replaced by the DL1 DS Link Nikon TTL Converter

Compatibility and sizing

Compatible Nikon cameras include the D2X, D3, D4, D40, D50, D60, D70, D70s, D80, D90, D200, D300, D300s, D500, D600, D610, D700, D750, D800, D810, D850, D5000 series, D5600 series, D7000 series, D7500 series, and Z6/Z7. Proper TTL operation also requires a current-model Ikelite DS strobe; strobe serial number compatibility is detailed in the product manual, and if you are unsure whether your housing meets the ICS-5 and TTL hotshoe requirements, check with the housing manufacturer before ordering.

Frequently Asked Questions

Is the Ikelite 4301.3 TTL Converter still available or has it been discontinued?

The manufacturer currently lists this version 2 TTL Converter (4301.3) as discontinued, with the DL1 DS Link Nikon TTL Converter as its official replacement. If you need the exact current equivalent for a new Ikelite housing setup, contact us and we can confirm which converter matches your camera and strobe combination.

Can I run two Ikelite strobes off one 4301.3 TTL Converter?

Yes. One or two strobes can be connected to a single 4301.3 Converter using an Ikelite-to-Ikelite sync cord, but running two strobes requires a dual sync cord rather than the single-strobe cord. Two strobes cannot be controlled by separate Converters even if the housing has two bulkhead connectors.

Will the 4301.3 work with non-Ikelite strobes?

No. It is designed for Ikelite DS-series strobes and is not usable with non-Ikelite strobes or non-DS Ikelite strobes. It also requires an Ikelite ICS-5 bulkhead connector and TTL hotshoe on the housing to function.

Is the Ikelite 4301.3 compatible with the Nikon Z6 or Z7?

Yes, the manufacturer's compatibility list for this converter includes the Nikon Z6 and Z7 mirrorless cameras alongside a broad range of Nikon DSLR bodies. Proper TTL operation still requires a current-model Ikelite DS strobe and the ICS-5 bulkhead connector on your housing.
