This booklet has been produced to enable you to obtain the maximum benefit and enjoyment from your new Agfa Silette. To acquaint yourself with the few simple points to be remembered in the use of this miniature camera we suggest that you put the camera through its various operations several times before loading a film. These operations should be carefully carried out in accordance with the instructions illustrated in this booklet.

The Agfa Silette is designed to take the standard 35-mm cassettes of black and white as well as—of course—colour film (Agfacolor).

It is equipped with an excellent miniature Anastigmat, either Agfa Apotar or Schneider Radionar, both f 3.5/45 mm focal length, in Pronto or Prontor-SVS shutter.

The Agfa Silette is fitted with a double and blank exposure locking device. This means that the same film can never be exposed twice on one frame and further, that the film cannot be wound on by mistake before an exposure has been made. If therefore the release button cannot be pressed, the film must either be wound on using the rapid winding lever, or the latter had not been fully moved to its stop; a further complete turn will remedy this without the loss of film. If the rapid winding lever cannot be moved, the camera is ready for use.

THE SHUTTERS

Before each exposure is made the desired exposure time should be set. The shutter speed is brought opposite the black double index mark (1/25 sec. in the illustration) by rotating the large milled ring (No. 9, fig. 2). The same index is used later for the distance setting.

When taking pictures without flash, the position of the synchro-lever on "X" or "M" is irrelevant.

In addition, the synchro-lever can be set on "V" to wind the delayed action shutter release. The setting on "V" can be made before or after winding the shutter.

In case that the lever has been set on "V" unintentionally, it may be reset without setting working the delayed action mechanism. The position "V" can be used also for flash exposures with selftimer, but with X-synchroniza-tion only.

It is advisable to reset the lever on "X" after each exposure with selftimer, to avoid any undesired delay in shutter release when taking the next picture.

1. Their flash duration,
2. Their light output,
3. The time taken from the moment of firing until they light up. The speed-synchronized shutter (Prontor-SVS) allows for these characteristics.

Application: The previous remarks indicate that, at any rate in the beginning, X-synchronization is easier to handle. With a flashbulb like the Speed Midget (SM), Sylvania SF etc. you can take synchronized flash shots at 1/25 or 1/50 second. The short duration of the flash within a slightly longer shutter exposure time will also catch subjects with moderate movement, such as children at play.

STOP — EXPOSURE TIME — DEPTH-OF-F1ELD The diaphragm stop is adjusted by rotating the diaphragm ring (No. 8, fig. 2) against a scale bearing the following stop numbers:

EXPOSURE TIME. The amount of light required to reproduce a given subject on the film is fixed. The exposure time and aperture are therefore dependent on each other. In choosing the aperture and shutter speed we have to preserve this relationship.
High aperture numbers call for slow shutter speeds (long exposure times) and low aperture numbers need fast speeds (short times).

DEPTH-OF-FIELD.
In addition to the exposure, the aperture also determines the zone of sharpness in front of, and behind, the focused distance. Small apertures (stopping down) appreciably increase this zone of sharpness, or depth-of-field. It also increases the farther away the subject is from the camera.
The depth-of-field is therefore dependent on the degree of stopping down and on the object distance. The exact ranges of sharpness determined by these factors for the various settings can be obtained from the table on page 30/31. The depth-of-field scale on the lens mount gives only approximate depth-of-field values.

EMPTYING THE CAMERA
If the exposure counting device reads 36, 20, or 18 respectively according to the length of film loaded, only one more exposure can be made. If during loading too much blank film was wound up, it may be found that the last exposure can no longer be wound on, i. e. the rapid winding lever stops halfway. In this case the last exposure cannot be made. After the

FOR THE AGFA CAMERA - AGFA FILTERS AND LENS HOOD
Filters are designed to reproduce correctly the brightness values of the different colours. We supply optically flat, homogeneously dyed filters to satisfy the highest demands. They are available in light yellow, medium yellow, yellow-green, and red-orange.
The use of light-filters naturally requires an increase in exposure time. Filter factors are used which, however, depend to a large degree on the

	medium yellow	No.2		1.8 - 2.3
	lyellow-green	No.71		2 - 2.5

Ask your photo-dealer for Agfa Filters in their modern transparent screw-top cases, and the handy Agfa Lens Hood, which can also be used together with the filters.
