The reflectors / flash techniques

The LEICASF 58 has two reflectors, the main reflector and the secondary reflec-

tor. The main reflector is designed as a motorized swivel and tilt zoom head. In

addition, it is equipped with an 18mm diffuser and a reflector card.

The secondary reflector is optionally switchable, its output can be regulated.

Main reflector

Swiveling and tilting for bounce flash

In its resting position, the zoom head (1.4) is locked to prevent accidental set-

tings. By pressing and holding the release button (1.4a), it can be swivelled

and/or tilted by stages for bounce flash to various indexed positions:

Swivelling (horizontal):30° /60° /90° /120° /150°/180° anti-clockwise

30°/ 60°/90°/120° clockwise

Tilting (vertical): 7° downwards

45°/ 60°/75°/90° upwards

Bounce flash illuminates the subject more softly and reduces dense shadows.

It also reduces the drop in light from foreground to background that occurs for

physical reasons.

To avoid color casts in your shots, the reflective surface (e.g. ceiling or wall)

should be color-neutral or white. For frontal fill-in lighting, the secondary

reflector can be activated additionally (see “Secondary reflector for bounce

flash”, p. 50).

To prevent direct light from the reflector reaching the subject, the tilting angle

should be at least 60°.

In close-ups and macro shots, the parallax error between flash unit and lens

may result in shadows on the lower edge of the image. To compensate for this,

the main reflector can be tilted downwards by an angle of 7°.

If the zoom head is tilted downwards, “TILT” is shown on the display as indica-

tion.

With the exception of this 7° downwards position, flash ranges do not appear

on the display when the zoom head is swiveled or tilted.

Notes on close-ups:

•

Certain minimum lighting distances must be maintained for close-up shots to

avoid over-exposure. The minimum lighting distance is about 10% of the range

displayed on the monitor.

• For close-up shots, make sure that the flash light is not obscured by the lens,

especially in the case of longer models such as telephoto- and telephoto-

zoom lenses.

Motor zoom adjustment

24, 28, 35, 50, 75, 90 and 105 (focal length in mm*) are available as zoom posi-

tions.

* The focal length values shown refer to the 35mm format (24 x 36mm). In the case of

cameras with smaller formats as a result of their effectively smaller angle of view, ex-

posures may also be made with shorter focal length settings of the main reflector than

those shown on the monitor. Example: With a LEICAM 8/M8.

2 and a 21 mm lens, the

24mm reflector position also produces flawless illumination.
