Continuous shooting: In this mode, the motor drive will auto-

matically trigger the shutter and wind the film for as long as the

trigger button is depressed. Framing rate will depend on the

shutter speed setting, as the motor drive's electronic interlock

with the camera's shutter automatically advances the film as

soon as the exposure is completed. Maximum framing rate is

approximately 3.5 frames per second (fps) at shutter speeds faster

than 1/125 sec.

Remember that continuous shooting at the maximum rate of 3.5

fps will result in a standard 36 exposure cassette being com-

pletely exposed in a little less than 11 seconds. Consequently,

you should exercise restraint when operating with the motor set

for continuous shooting. Many photographers, however, prefer

to leave the camera set for continuous shooting, lifting their

finger off the trigger button the instant the exposure is made.

This technique results in single-frame operation, but readies the

photographer for taking sequence photographs should the situ-

ation or need arise. The usable shutter speed range when the

MD-12 is set at "C" is from 1/2 second to 1/1000 second with

the FM. With the FE, in addition to the automatic setting

(AUTO), you can set any of the marked speeds including M90.

The "B" setting cannot be used.

The FE's automatic exposure capability allows you to follow

subjects as they pass through areas of differing brightness, yet

still obtain~ correctly exposed results.

Although widely varying brightness changes of EV 4 or more

may sometimes result in over- or underexposure for the first

frame following the transition, this situation is rare in practice

and thus likely to be of little consequence to the average pho-

tographer.

Important! After shooting, make sure that you turn the motor

drive off.

Note: The camera/MD-12 combination is designed to work smoothly

under a wide range of climatic conditions. Sub-zero (centigrade) tem-

peratures, however, have a very severe effect on any mechanism. For

faultless performance under these conditions, we recommend that, for

continuous shooting, you do not use shutter speeds of less than 1/30

sec. The use of slower shutter speeds may result in erratic operation. If

it is imperative to use shutter speeds of less than 1/30 sec., switch to

single frame shooting.
