Mamiya-Sekor SFC Mamiya’s long experience and concentrated technology have made possible the development of the all new MamiyaSekor SF C 150mm f/4 Soft Focus Lens. A special type of spherical aberration has been purposely introduced into this lens to produce photographic images that are sharp yet which have an alluring softness.
The depth-of-field and the degree of softness can be easily checked by stopping lens down to the preset aperture by operating the depth-of-field preview lever. Other functions All other functions such as removal and attachment of the lens, operation of mirror lock-up, etc., are the same as for standard Mamiya-Sekor lenses.
