You need to zoom a tad according to Edward lai to get it to work with the mark IV. The lens works with all 28mm cameras is not specific to the mark IV is a lens that nauticam has planned for a long time
The camera looks very interesting for video not so much for underwater stills I will get one and stress it up on land before getting into the water
