The SE-U430 System Expander enables the use of a large studio viewfinder and studio lenses with the UHK-430, converting the portable camera into a full facility studio camera. Installation of the camera into the SE-U430 is very easy, and conversion back to portable configuration is quick for maximum operating flexibility. The camera can be slid back by releasing the lens lock while maintaining the optical axis of the lens and camera. This makes the swapping of large lenses very easy.
