Flash photography

In addition to the photocell for ambient light, the

LEICA M7 is equipped with a second photocell for

flash (arrow). This silicon photocell, located on the

right below the shutter, enables the camera to

measure the light emitted by the flash through the

lens, at the working aperture. The Through The

Lens flash metering system on the LEICA M7 is

center-weighted.

The LEICA M7 can meter and automatically con-

trol the flash with

• the LEICA SF24D system flash unit specially

developed for the LEICA M6TTL/M7 and

LEICA R8/R9) (Order nos.14444, silver or

14448, black) or

• Flash units that meet the technical require-

ments of System-Camera-Adaption (SCA) for

the 3000 system and have the SCA-3502/3501

adapter.

If the flash unit used has the appropriate func-

tions

, the LEICA M7 also allows other, more inter-

esting compositional flash techniques to be used,

such as synchronisation of the flash to the 2nd

shutter curtain rather than the 1st as is normal,

use of the flash with faster shutter speeds than

the synchronising speed of 1/50s and strobe

flash (for more details see the appropriate sec-

tions below).

For flash operation on the 2nd shutter curtain and high

speed synchronised flash, the SCA 3502 adapter is re-

quired. Strobe flash, on the other hand, is possible with

the SCA 3501.
