ewa-marine AV110-L autofocus-adapter
For use in cameras with long zoom (e.g. 300 mm focal length) in the ewa-marine U-AZ housing (camera and lens 170 to 230 mm).
The AV110 was used by us for the use of autofocus lenses in the products of the U-A.. Series. The AV110 forms the fixed connection between the tripod thread of the camera and the optical front glass of the housing. This ensures that the lens can adjust when focusing in length without having to fight against the resistance of the water. This also ensures that the water pressure does not affect the lens, otherwise this could be adjusted or even the AF motor may be damaged.
