Hasselblad Carl Zeiss Makro-Planar CF 120mm F4 T* lens in very nice condition. (1984).

Macro pictures are usually taken at small working apertures to increase the depth of field. At a first glance the wider initial aperture  there fore seems unnecessary. But as the considerable increase in extension when taken close-ups results in a marked reduction of the effective lens speed and hence in focusing screen brightness, the maximum aperture of f/4 doubles the brightness of the screen image compared with the f/5.6 lens. Furthermore, the shallow depth of field associate with the new initial aperture makes it easier to recognize the plane of sharpness. Both factors facilitate the work of the photographer and give more confidence in the composition of his picture. The recommendation that only extension tubes and no supplementary lenses should be used for close-ups below the shortest marked distance holds good also towards the new Macro lens.
