Enhanced manual strobe control (M-TTL):
Operation in this mode gives the ability to use non-doubleflash compatible strobes with the converter.

strobes provided with only minimal or non-existent manual control.
Activation:
-set strobe to TTL
-set camera to synchronisation on second curtain (REAR)
or
- set adjusting knob on the converter to global manual mode
Flash power selection:
The flash power is selected by using the flash exposure compensation and the exposure compensation.
The result is the sum of both values. Hence the M-TTL flash power can be adjusted
by either the exposure compensation (EC) or the flash exposure compensation (FEC) of the
camera. The flash power is halved every -1.0 EV. In case both, EC and FEC, are set to +/- 0 EV,
