1) you have to set the ISO/ASA value to be same as your camera. So if your camera setup is ISO400, you have to do the same to the flash.

2) I do not know the meaning of the blue and the red color but the value 1.4 2 2.8.. are the aperture value you need to set as equal to the camera setting.

In other word, put your camera in Av or manual mode. what you set on your camera, you just set it accordinly on the flash and shoot

On the other hand if you want to do flash compensation, like + 1 stop, just play with the apperture value on the flash. i.e if you camera use F2.8, you can set the flash setting to +1 stop at F4. This will give you +1 stop compensation

THks Jim,
Well... according to to the manual,
Red setting is for shooting at distances of up to 20feet(6m) at f/4 ASA100 / DIN21 at wide position.
For longer distances, use the Blue setting which allows shooting up to 30feet(9m) at ASA100 /DIN21 at wide position

erm, that depends entirely on yourself. ;)
you can bounce it upwards, 60 degrees, to the left or to the right (if the flash allow swivel and tilt) ;)

For example if I want to take shoot during dark sky(ard 8pm in the nite) enviroment with landscape + portrait. What is the angle of the flash head should I set. Pls advise. THks.

i believe it really depends on what u are trying to capture, just the foreground only? or fg+bg? it also depends on are there any other light sources around? or solely relying on the flash output and etc...

i would strongly suggest you to experiment on your own, cos a different situation requires different solutions... :dunno:

and its always better to have a feel of it yourself, no hard and fast rule here. :D maybe some of the more pros might be able to give better advice. =)

The flash head can zoom, right?
So if the head zoom at W1, then the switch at W1, if zoom at T, then the
switch at T, hope I am right.

Well... the flash head can slide in n out in 3 position(N, S & T). Manual shows that 35mm lens @ N, 50mm lens, S & 85mm lens @ T & lastly 28mm lens is somehow for N + Diffuser(W1) which I dun quite understand. As for my cam is stated Olympus Len AF zoom 6.3 ~ 63mm 1:2.8 ~3.7 so which should I set.
Pls advise.

THks N RGds
