Leica SF24D Flash Unit

The optimised functions offered by the LEICA SF 24D make it possible to control flash exposure directly through
the camera, making this unit the perfect accessory for a wide range of Leica cameras. The LEICA SF 24D is
suitable for use with Leica rangefinder and SLR cameras, and can also be connected to the LEICA CM analogue
compact camera and the LEICA DIGILUX 2. The flash unit automatically recognises the type of camera to which
it is connected, and adjusts itself to the relevant operating mode. Ease of use and compatibility with the
full range of modern flash techniques are features of the LEICA SF24D.


The LEICA SF 24D has retained all the application features of its predecessor model the LEICA SF 20, and has
complemented these with new functions. For example, the range of automatic apertures has been enhanced.
All apertures from 2.0 to 11 are available with this new dedicated flash unit. The LEICA SF 24D also provides
improved flash compensation of +/- 3 EV.


The illumination angle of the LEICA SF 24D corresponds to a 35 mm focal length for the 35 mm system.
The two ancillary screens supplied with the unit for the wide angle and telephoto range cover focal lengths
of 24 mm and 85 mm respectively. The flash unit automatically recognises the two diffuser screens supplied,
and immediately adjusts the range display to the new guide number.
