I used with a Nikon 60mm f2.8, on a very dark and gloomy day. For reference purposes, the water temp was 4 degrees, and I lost all sensation in my hands for most of the dive (despite dry gloves!) The port gives really nice results-sharp and it corrects the parallax that you get with conventional flat ports. I will definitely try it some more
