Generally, there are two ways to install an attachment lens such as wide conversion lens or close-up lens on an underwater housing for compact camera. For those housings equipped with screw mount lens ring, screw mount type attachment lens can be directly installed. A housing without this lens ring need to have a Mount Base or Lens Adapter Base to hold an attachment lens.
A Mount Base is a multifunctional base and key component to add an attachment lens and strobe on a compact underwater housing. Different four Mount types available including [28LD], [28AD], [AD] and [M67] support you to shoot with wide conversion lens, fisheye conversion lens or close-up lens to suit to different subject.
A Mount Base is fixed on a housing at tripod base and lens port to provide reliable installation and precise alignment of optical accessory together. Also they help to have a strobe etc. without excessive lord on combined housing.
