Flashlights
The Macro Ring Flash MRF 3500 has a fl ashlight
with the guide number 6 on both sides.
These can be separately activated and deacti-
vated by a switch which is located on the back
of the unit. To activate the selected fl ash lamp,
simply position the switch at "ON".

focus in poor lighting conditions but only if the

the TTL mode.
