TTL exposure control
The accessory shoe of the LEICA R6 has a
central hot-shoe contact and the control
contacts for any electronic flash fitted with
an SCA 351 or SCA 551 adapter. Within the
range available for flash, you may use any
aperture available on the lens fitted (see the
manual supplied with your flash unit).
\Vith the exposure meter switched on (see
page 18) and an SCA300 or SCA500 flash
unit used in conjunction with an SCA 350,
SCA 351, SCA 550, or SCA,551 adapter,

When the shutteris set t6 X, the t symbol
at lower left in the viewfinder flashes twice a
second.
When the shutter is set to any speed from
r/oo s to 1s, the f symbol remains constantly
1it.
If the shutter speed set is too fast for flash
photography, i. e. Utzs s to l/rooo s, the I
symbol does not light.

displays in the viewfinder lights, but TTL
