Aquatica has assembled and redesigned its whole range of close up accessories under the ACU system banner, which stands for Aquatica Close-Up System.
The ACU system consolidates all the components of our macro and close-up accessories (new and existing ones) into a comprehensive underwater close-up system. In doing so, the engineering department reviewed the system so that every component would work flawlessly with each other. Aquatica took the double element close up lenses it already had, now known as the ACU5 and ACU10, and matched every component of the system to the optical characteristics of the macro lens of your choice.
This consolidation makes it simple for you to navigate through the system and pick the right setup for your macrophotography requirements.
With top quality close up lenses as the corner stone of the ACU system, a new Mini Macro Port with a much smaller frontal signature was created, on its front is a bayonet ready to accept the ACU Flip Holder in both single and double versions. To optimize the ACU system to its full potential, the port extension ring selection was revised with a new series being introduced. New gears for manually focusing the popular macro lenses have also joined the ranks of the Aquatica system.
