NOTE: The camera can read the focused distance from a EF lens and regulate the amount of light from its flash (with either the Mamiyalite 18R or MZ 36R). This was a unique feature of the Mamiya EF lenses and Z-series cameras, comparable to the Nikon AF D lenses of today. This distance readout is not possible with the E lenses.

Additional Accessories Available for Z-Series Cameras
The following are the original Mamiya accessories available for this camera:

Filters: A series of five high-quality filters, designed to maintain the high performance of the Mamiya-Sekor E-series lenses. They come in 49, 52 and 58mm sizes, and in the following types: SY48 (Y2), SO56 (O2), SL39 (UV), YG, SL-1B (skylight).
Lens Hoods: Lens hoods are available as screw-in accessories, or built-in as retractable hoods. Always use the lens hood designed for the specific focal length of the lens being used.
Diopter Correction
Many near- and far-sighted persons have difficulty looking through a viewfinder wearing glasses, but cannot focus accurately with them. Diopter Correction lenses, available in six different strengths, adjust for this deficiency.
Rubber Eye Cup with Adapter: This adapter is required for attaching the diopter correction lenses to the camera. The rubber eye cup helps prevent unwanted light from entering the viewfinder.
Magnifier: Useful aid for critical focusing required in close-up photography. Mounts to rear viewfinder. Image size is doubled, and the Magnifier provides for diopter adjustment.
Angle Finder: Useful for low angles, the Angle Finder has click stops every 90º and freely rotates 360º. Has built-in diopter adjustment.
Auto Extension
A set of three rings of different lengths, which mount singly or in combination between the camera body and lens, directly coupling with the camera metering system and the lens automatic diaphragm.
Auto Bellows: A versatile bellows unit for photomacrography. Rack and pinion control allows precise adjustment. Additional features include a double cable release for diaphragm automation and provision for mounting the lens reversed, for large magnifications.
Slide Copier: Used with the bellows unit, the slide copying attachment is mounted in front of the lens to allow copying of slides and filmstrips. It has a slide stage that makes it easy to crop mounted slides, and a removeable film tray to facilitate copying long rolls of 35mm film.
Bellows Stand: Actually a small stage for photographing small objects. The platform rotates to allow for best positioning, and has clips to hold objects in place. The surface has a reflectance of approximately 18%, ideal for exposure measurements. A clear glass stage is provided for backlighting and incident light measurement.
Close Up Lenses: Convenient attachment lenses which screw directly to the filter threads of the master lens, enabling swift and easy conversion to close-up photography (not a substitute for macro lenses).
Mamiya Winder: Mounting the Mamiya Winder on the camera eliminates the need to advance the film manually. Continuous sequence photography is possible at the rate of approximately 2 frames per second.
Flash Units:
Three different units are available. The Mamiyalite ZE is a clip-on auto flash unit with a guide number of 17. It features two auto flash ranges plus manual flash override, and will automatically control flash intensity within the flash operating range. The Mamiyalite MZ 18R is a clip-on automatic electronic flash with guide number of 18. When used with a Z-series camera, the flash unit automatically synchronizes for flash at 1/60. When used with EF lenses, the camera will automatically select the aperture to obtain proper exposure in relation to focused subject distance and film speed. The Mamiyalite MZ 36R is a grip-type flash unit with a guide number of 36. It also automatically selects camera aperture in relation to film speed and distance. In addition, five different flash intensities may be selected, and the MZ 36R also has an electronic remote control and slave unit.
