SU-4 as a device will be refering to the optional part sold separately.

Isn't it confusing the way Nikon name the terminology?

That is why it is stated as "SU-4 type" multiple flash.

which is why I stated. ON THE SB-800 only. but not other flashes.

You are right, for a while I was mistaken.

Hmmm...

Firstly, I don't believe the SB600 has a SU-4 mode. It can be used to trigger flashes that support SU-4, such as the SB800, but it does not have this function itself.

Secondly, and more importantly, to use the SB600 as a remote flash and to trigger it with the D70's built-in flash, do the following:

1. Switch to the CSM by pressing and holding the "-" and "zoom" buttons for about 3 seconds.

2. Navigate the menu by pressing the "+" or "-" buttons until you come to an item that looks like a horrizontal lightning bolt.

3. Press the mode button to change this setting to "On".

4. Press the ON/OFF button to exit the menu.

5. Press the mode button to get to the CH (Channel) setting and press the "+" or "-" button to change the channel to "3".

6. Press the mode button again to get to the Group setting and change this with the "+" or "-" button to Group "A".

7. Press the mode button again to save the settings.

8. In the D70's CSM menu, the one that looks like a pencil, go to setting 19 "Flash mode" and change this to "Commander Mode" use "TTL" mode as a start and experiment with the others at a later stage.

9. Set your flash at an appropriate angle to the camera, activate the flash on the D70 and fire away.

Remember, Channel 3 Group A. This is necessary when triggering the SB800 with the D70 as well.

Hope this helps.

Cheers,

Matt

SB-80DX will just function as a normal slave. Guess it can be considered normal SU-4, since SU-4 only triggers the flash.

Pardon me if you don't know what I talking about

I'm so embarassed by saying that it's not possible...guess I should be the one to RTFM... Anyway, the steps that deadpixel describe, do work for SB800 as well...but what's the diff using that mode and SU-4, that is something that i'm quite confused...really really must RTFM...

SU-4 mode is dumb slave flash mode - it will fire the flash when it sees another flash firing, and turn off when the other flash stops. Will only work if your D70 flash mode is set to manual - as in any other mode, the pre-flashes will set the flash off at the wrong time.

If you want TTL (in this case i-TTL), remote mode is the mode to use.
