Wow, that was a significant camera upgrade.First time out with the new camera in Curacao. Sony a7iv, 28-60 lens, Marelux housing, Nauticam WWL-1B, and Retra Pro X strobes. Significant upgrade from the Sealife I was playing with!
Be kind, this is just a hobby.
What was your reason for going with the retra, had you used other strobes previously?
