Mamiyalite MZ36R is an automatic electronic flash especially developed for the Mamiya ZE series cameras. Besides permitting selection of a wider range aperture than the conventional reflected light integration system automatic flash, the Mamiylite MZ 36R automatically controls the quantity of light according to the distance to the subject by means of a revolutionary radiated light integration system (when used in combination with the ZE-X camera and an EF lens). In the manual flash mode, the quantity of light can be adjusted over five stages from the quantity of full Hash to 1/16 of the former (G.N. 9).

Features

1. Distance Priority Flash AE System:

(Radiated Light integration System )

When the ZE-X camera and EF lens is employed and the Hash is set to MZ-AUTO, the flash is operated by the distance priority Hash AE system. This system controls the quantity of light according to the distance to the subject, read from the EF lens, so that optimum exposure can be obtained without being affected by the reflectivity of the subject. a. If the aperture is set to a desired aperture value, the system automatically emits the optimum light quantity calculated from the set aperture value, the distance to the subject, and the film sensitivity. b. If the aperture is set to AUTO, the camera automatically determines the proper aperture according to the distance to the subject and the film sensitivity.4www.butkus.org

2. Ordinary Automatic Flash System:

(Reflected Light Integration System)

When using any lens other than the EF lens, the flash is operated at all times in the same way as an ordinary auto electronic flash. That is, the system automatically controls the quantity of light according to the amount of light reflected back to the flash from the subject, the aperture, and the him sensitivity. a. When using for the ZE-X camera attached an E lens, and the flash is set to MZ-AUTO, a proper aperture will be set automatically. If you desire, the aperture can be set manually within the range shown in the Table (T-2). b. When using cameras other than ZE-X, set the flash to AUTO and select an aperture according to the film sensitivity.

Automatic Setting of the Shutter Speed:

If a ZE series camera is used, the shutter speed is automatically set to a synchronization speed of 1/60 sec as soon as the flash unit is fully charged. Even if the shutter speed was set to a high speed, it is automatically adjusted to 1/60 sec. to enable flash photography.

If the shutter speed of the ZE-X or ZE-2 camera is set to a slower speed than 1/60 sec., the shutter operates at that speed. This is effective for shooting a dim background with an extended exposure in conjunction with use of the flash.

Prevention of Flash by the Crossover System of the ZE-X Camera:
If the camera with the EF lens or the E lens is set to the Crossover System in the AE mode, the flash will not operate even after fully charged in situations where a correct exposure can be obtained without flash, that is, it will not operate when the shutter speed is above the "camera shake" limit.

For instance, the flash does not operate if shooting is possible at a shutter speed faster than 1/30 sec. with a 50mm lens.

When you want to use a flash in such situations, disengage the Crossover and the flash will operate after it charges regardless of the brightness.4www.butkus.org

Loading Batteries

1. Tilt the flash head upward and push up the battery chamber cover to remove (Photo 2). 2. Pull out the cartridge of the battery chamber.

Insert batteries into the cartridge, making sure that the polarities of the batteries match the marks on the cartridge.

3. Insert the cartridge into the battery chamber.

The cartridge may be inserted upside-down.  (Photo 3).

4. Match the mark on the battery chamber cover with the mark on the side of the battery chamber and push down the cover while pushing the cartridge into the battery chamber.

· Use eight 1.5V M-size alkaline-manganese batteries or Ni-Cd batteries.

· Keep the power switch/channel selector switch OFF when not using the flash, to avoid consumption of batteries.


Test Firing and Open Flash (Photo 4)

Turn ON the main switch and press the pilot/test button after the pilot lamp lights. To test the flash, set the flash mode selector switch to positions other than MZ-AUTO. If the flash mode selector switch is set to MZ-AUTO, the flash will not operate unless it is mounted on the ZE-X camera and the shutter release button of the camera is pressed.

The flash can be used as a transmitter when combined with a receiver MZ. Operate it in the same way as in the test firing procedures.

Attaching the Bracket

1. Match the notched part of the outer rim of the clamp with the white dot on the bracket and press into position (Photo 5).

2. Rotate until the white dot on the bracket faces upright to lock the bracket into position (Photo 6).

3. Screw the camera set screw into the tripod socket of the camera.

· To remove the clamp from the bracket, press the clamp release button and rotate to the notched part and pull out the bracket.

· To shift the flash unit up and down or to rotate it left or right, use a coin to loosen the two clamp lock screws (Photo 7).

· The bracket MB-1 equipped with two positioning pins is available as an optional for medium format cameras such as M645 and RB67. The bracket prevents accidental or inadvertent twist of the camera.

When Using for ZE-X
(1 ) Attach the sensor base to the hot shoe.

(2) Insert the main cord into the main cord socket of the flash.4www.butkus.org

(3) Insert the shutter release cord into the release socket of the camera. Now the shutter of the camera can be released by pressing the shutter release button of the flash unit. Exposure information will appear in the viewfinder if the shutter release button is pressed half way, in the same way as the shutter release button of the camera.

Using on the ZE-X with the EF Lens:

A. Using the flash With the aperture set to a desired aperture value: 1. Set the desired aperture value to the center index by fuming the aperture ring, f/5.6 for instance (Photo 8). 2. Turn the distance priority switch of the EF lens by pushing it in the direction of the arrow (Photo 9). When the switch is on the opposite side, it shows orange on the left indicating it is fumed off, and in this state, the EF lens functions in the same way as the E lens. 3. Set the shutter speed dial of the camera to "A". 4. Set the flash mode selector switch (12) to MZ AUTO, and turn on the main switch (19). The channel number may be set to either CH1 or CH2 (Photo 10).

5. A few seconds later, the pilot lamp will light to indicate that the flash is ready to fire. If the shutter button is pressed halfway the EF mark indicating completion of charging and the previously set aperture value will appear in the viewfinder.

Automatic Aperture Control by the Crossover System:

When the focusing distance of the subject is too far away for a proper exposure at the aperture setting, the Crossover System will automatically correct the aperture to obtain a proper exposure. The "O" crossover symbol appears at the right of the aperture value.

If the subject is too far away for a proper exposure even at the maximum aperture of the lens in use, the maximum aperture indication in the viewfinder will flash to inform that the subject is out of flash exposure range.

When the Crossover is Disengaged:

The set aperture value is fixed. If the subject is too far away for the set aperture value, that aperture value will flash as a warning In such a case, open the aperture until the flashing ceases. When the aperture is set to f/5.6 with ASA100 film, for instance, the f/5.6 symbol will flash when the subject distance exceeds about 6.5m.4www.butkus.org

· Overexposure will occur in a short distance as the aperture is set between f/8 and the maximum aperture (f/1.4) since the exposure exceeds the automatic flash range. Stop down the aperture (f/ 8 or smaller) in such a case.

· The automatic flash range varies with the sensitivity of the film. Refer to Table (T-1 ) to use a film of sensitivity other than of ASA100. The figures on the table represent the distance in meters.
