Ikelite DL5 DS Link Canon TTL converter
Came as a part of a second hand strobe kit that I had purchased but I have no need for it. Usually sell for ~$650 new in Australia. Didn’t come with the bulkhead or dust cap when purchased so they aren’t included. Happy to pay for shipping too and refund if it doesn’t work as I can’t test its function myself (should work but my housing has inbuilt TTL so couldn’t mix them).
