I just remembered that in CF make lenses with and without shutters (FE). ALl mine have the shutters in them.

THIS PLANAR LENS is characterised by an extremely uniformb edge-to-edge sharpness at all apertures, resulting from the excellent correction of all lens aberrations. As indicated by its name, the astigmatic flatness of the image field is outstanding. The 80mm Planar is available with and without shutter enabling all Hasselblad SLR cameras to be used with this standard focal length. The FE (non built-in shutter lenses) version is provided with the same optical specifications. Considered as a "standard" lens in the 6X6 format. One of the most versatile lens, good speed, and very high optical quality.
