Hasselblad Extension Tube 16E. Most close-up assignments can be solved simply by adding extension tubes between the lens and camera body. Four extension tubes are available for the Hasselblad V System and can be used either singly or combined to achieve the magnification scale desired. The series of extension tubes automatically connect the lens and camera mechanism together to utilize the camera's functions fully for ease of use. With the exception of Extension tube 8, which cannot be connected directly to the 200-series cameras, they also feature a data bus coupling to transfer data from the lens to the exposure metering system of the camera.
The image quality of any camera system is only as good as the lens that forms the image. From the very beginning, this basic concept has guided Hasselblad's lens philosophy. The V System offers the largest range of superior quality lenses of any medium format system. Hasselblad's long expertise has resulted in lenses with unrivalled specifications, exceeding even the exacting demands of digital photography.
