How to operate the Motor Drive MF - HTML & Pdf.file
TEM is a concept of the ideal
single lens reflex camera, a dimension into which the F-1 is a true pioneer. "T"
stands for through the lens metering. "E" stands for Electric Eye control
of exposure. And "M" stands for Motor Drive. Metering is, then, performed
by TTL, exposure by EE, and film advance by the Motor Drive Unit. Yet, the backbone
of the TEM is the Motor Drive Unit, thanks to which the whole ensemble works to create
a suitable instrument for the most demanding photographic tasks.
Now, when the F-1 appeared, the Motor Drive was planned to emphasize the variety
of its possible applications, since it has a device to make recording of scientific
observation possible. However, the quest for new developments did not end there.
Two further achievements of the Motor Drive System were developed one after the other.
A unit to be used exclusively for high speed photography was the first to follow,
and then came the new MF system.
The high speed Motor Drive Camera was born out of the F-1's Motor Drive System, and
may be~ considered as an issue of the very summit of technological excellence.
The MF is a component Motor
Drive System designed for maximum flexibility. It was designed after going all the
way back to the simplest possible form of motor drive photography with the F-1, and,
then, from that simplest form it went on acquiring greater and greater versatility
through the addition of the various accessories into the Motor Drive System, of which
the axis is the MF. It is possible to use it with the Film Chamber 250 or with the
Servo EE Finder, or with both, and the highest degree of precision has been preserved
to ensure its interchangeability.
The MF can be divided into
two parts: the driving part and the grip inside which the battery case is enclosed.
The driving part is screwed on in place of the bottom cover of the camera, and the
grip is inserted into the bracket on the side of the Motor Drive and is fastened
with the screw that tightens the bottom of the grip. The grip is provided with a
shutter release button, and film is fed at a speed of up to 3.5 frames per second
by using the Motor Drive System.
Top Quality Operation
The inner mechanism is quite
compact though it consists of the conventional Motor Drive with two synchronous motors,
one for film advance and the other for shutter release in order to increase stability
of performance. At the same time, taking into consideration the needs that arise
in sports news coverage, the grip with the battery chamber was placed in front on
the right hand side to make it easier to hold the unit either vertically or horizontally.
The shutter button was conceived in such a way as to adapt perfectly to the hand,
and the grip is detachable, so that the Film Chamber 250 may be used. In cold climates
it can also serve Wide Coupling Range of Shutter Speed
Automatic film advance and
shutter release makes continuous photography possible at up to 3.5 frames per second
with shutter speeds of 1/60 of a second or faster. When used together with the Interval
Timer L, automation is extended to photography as slow as 1 frame every 3 minutes.
A Complete System of Remote Control
One of the main features of
the Canon F-1 System is its ability to perform fully automatic, unmanned photography
when a Motor Drive is used together with the Servo EE Finder. The Motor Drive MF
has a mechanism that includes of a small relay whose circuit controls the motor.
The application range of remote control has been considerably widened because it
is based on the operation of this relay. Therefore, not only can we meet requests
for accessories destined to standard service conditions but also for a method of
control based on special application of the specifications. External control is undertaken
by connecting the various accessories to the remote control jack on the side of the
body.
Development of the
System
Many accessories are being
developed simultaneously with a view to expanding the MF system, but always paying
attention to the fact that accessories developed up to date may be used without change.
The Connection of the Film Chamber 250, Connecting Cord and Grip MF The
Film Chamber 250 is attached in place of the back cover of the F-1 camera in the
conventional way, and adjustment or change is not necessary to attach the MF to it.
However, since theGrip MF is in the front of the F-1 body and, therefore, obstructs
the attachment of the chamber, it should be removed, and the cord connected. This
cord is used when the chamber is attached and also serves to keep the equipment ready
for immediate use in cold climates by means of the external power source. Yet, the
length of this cord is limited, since remote control entails excessive battery consumption
when long connections are used. A long extension cord for remote control is also
available.
Connection with the Servo EE Finder
The Servo EE Finder is connected
to the special socket on the front of the motor drive unit's body. The connection
cord is also specially designed.
Interval Timer L
The Interval Timer L is an important accessory for increasing the TEM's range, since the ability to regulate photographing time in unmanned photography is indispensable for scientific observation. While time could be set at one frame per minute with the conventional Motor Drive Unit, this range is now extended to one of intervals of half a second to 3 minutes, and the shutter release button can be locked under the Interval Timer L's control.

 |
Therefore, without any attendance, automatic photography can be performed for an hour and 48 minutes at intervals of 3 minutes with a 36 exposure roll of film. |
Power for this electronic timer is supplied by the motor drive unit. The timer features a very high precision in its compact size. Once the timer is attached, operation can be started with the button, and just by holding it the shutter release button on the grip will be freed. This timer is inserted into the socket of the Extension Cord E1000. The timer scale is graded into 10 stages and its relation with the shutter release speed is as follows:
Interval Time (sec.} T
Shutter Release 1/15 - 1/20001/4 - 1/20001/2 - 1/20001 - 1/2000 Speed This timer is screwed into the socket on the side of the Motor Drive MF.
Remote Switch 60 MF
To use the Remote Switch 60 MF insert its 60cm cord into the socket that is also
used to attach the Timer or into the Extension Cord E1000's socket. This switch when
pressed releases the shutter, and by sliding it the shutter release button is locked.
The Light Emitting Diode (LED) serves to verify the operation.
Extension Cord
E1000
This connection cord is 10 meters long and has a socket for the Remote Switch 60
MF and the Interval Timer. It serves to extend the range of remote control.
Self Timer E
With this Self Timer E which was originally designed for a high quality 8mm movie
camera, photography can be performed with 1 O-second shots with a delay of 10 seconds.
It is attached in the same place as the Interval Timers.
Interval Timer
E
This timer was also designed for a high quality 8mm motion picture camera for single
frame photography, and it is adjustable from 1 to 60 seconds. It is attached in the
same manner as the Self Timer E.
Time Lapse Programmer
This Programmer is provided with a circuit to regulate time from half a second to
24 hours, and is capable of a variety of combinations of length of continuous shooting
time and intervals. It was designed for both a still camera and an 8mm movie camera,
and is used in order to perform single frame photography of the separate stages of
movement, and for work sampling, indented and otherwise.
 |
With this programmer, long-time photography for nature observation can be automatically performed at the rate of one picture per day as the longest interval. It is possible to increase the number of shots to record changes by the hour. |
