Hasselblad Extension Tube 16E

The series of extension tubes covers the range up to the shortest bellows extension. They automatically connect to the lens and camera mechanism to utilize the camera's functions fully. With the exception of Extension tube 8, which cannot be connected directly to the 200-series cameras, they all feature a data bus coupling, transfering data from the lens to the exposure metering system of the 205FCC and 203FE cameras.
