Hasselblad's XH Converter 0,8 is designed to allow the use of all HC/HCD lenses on X System and 907X cameras. Unlike your standard lens converters, this has the opposite function of a teleconverter. In fact, this converter actually reduces the focal length of your attached lens by a factor of 0,8x, widening the field of view and even will increase the maximum and minimum aperture with 2/3 stops. Furthermore, when using this converter, you'll also see improved lens performance across the frames, in terms of contrast and sharpness. This is a unique converter that features Hasselbald's classic and high-quality construction.
