These photos were shot with a Mamiya RB ProS using a Mamiya Sekor 150mm soft focus lens. I reckon the camera is close to forty years old. It's medium format meaning it uses 120 film and produces a 6x7 negative. It is entirely mechanical unless you use a metered finder which uses batteries. You don't have to though.

The camera is modular to use a more recent term. Everything can be taken apart and changed. Viewfinder, lens, focus screen and film back. The shutter is in the lens. The camera body is basically a light tight box with a lever to cock the mirror, bellows for focusing and a shutter button.

The RB comes from rotating back. The back goes on an adapter which allows you to rotate it from landscape to portrait orientation. Given the weight of the camera, this is a nice feature. 67 is, of course, the negative format.

The lens used here is the Mamiya Sekor 150mm Soft Focus lens. I became addicted to this lens the first time I used it.

A special type of spherical aberration has been purposely introduced into it to produce photographic images that are sharp yet which have a softness and glow. It uses 3 types of optical glass which corrects for all other types of aberrations.

The soft focus effect is eliminated when the lens is stopped down to f/8 or more and the lens can be used as a regular lens. These photos were shot at 5.6 and 4.0.
