p.1 #1 · Canon 580 EX II will not select as disabled Master
Any reason why I can't get the 580 EX II option as disabled Master to come up? The slave is a Lumo Pro LP160. Does it need to have a Canon EX model set up as slave to allow 580 EX II to be selected as Master disabled?

Turn on unit
Mode to Manual
Hold Zoom to select Master On with dial, select with set button
Not sure why I can't change from channel 1 to anything else, not really that I need to...just curious. The flash icon shows it being a master because the arrow is pointing away, but also shows the 3 lines to indicate it is in Master "ON" mode, it also says "MASTER" to the right of "CH."

Ok now hang on a little. I just googled the slave flash your using and from what I read you are going to need the master the fire anyway.
From theIr web site: "An exciting new feature will allow even more integration with existing flash systems: the new digital optical slave will ignore the 'pre-flash' - a common feature of TTL flashes for obtaining exposure information. This important addition enables photographers to manually control the LP160, in conjunction with their TTL flashes, without transmitting a TTL signal or exposure information, or having the LP160 flash when the pre-flash activates.
So if the slave ignores the pre flash but you master is set to just master (not be part of the expossure) then all you will get is the coded master pre flash. So your slaves will be ignoring the only flash of light from the master.
And if your optically slaving and ignoring the from a flash that you don't want as part of the expossure then why even use a ttl master. You could trigger the slave with any really cheap non ttl head. As long as you could turn the power down to minimal amounts you wouldn't get much expossure from it anyway.

I tried that, but it's still firing during the exposure.

Okay, after turning the Speedlite to Master mode and pushing the center button, you need to press [Zoom] again until the word "On" is flashing, then turn the dial the opposite direction from before until "Off" is flashing and "Master" is still on, then push the center button again.
Same for setting the Channel and other functions; just keep pressing the [Zoom] button to cycle through the various functions, then once on the desired function use the dial to select the option for that function.

You're a genius, BrianO...thanks once again for saving the day!

You're most welcome. Glad I could help.

This is a seperate question, and as Ian was trying to point out, you can't use the Canon Master function in non-firing mode with the LP160.
The LP160 isn't Canon Wireless compatible. It has a simple optical trigger that will fire in sync with another flash, but the Canon flash would have to be set to fire for exposure in order to trigger the LP160 in sync.
You can set the LP160 to ignore preflashes, but it MUST see a main flash in order to go off.

Doesn't the Canon have to fire a pre-flash anyway even for other Canon's?

Yes, but that has nothing to do with the LP160.
If you're using Canon slaves, you can set the Master to send only the coded command pulses and the metering preflash, but NOT an actual exposure flash.
The Canon Slaves will receive the command pulses, set themselves, and then fire when ordered to by the last command pulse.
The LP160 CANNOT do that; it's not compatible with the Canon Wireless System. All it has is a dumb optical trigger that will fire when it sees another flash go off. If your on-camera flash is set to not fire, there is nothing for the LP160 to trigger from.
So, in summary, if you're using Canon slaves (or some fully-dedicated third party flashes) you set the on-camera flash as a Master. If you're using the LP160 as a slave, you can leave the on-camera flash in regular -- non-Master -- mode, in either Manual or ETTL. If you use ETTL, you'll need to program the LP160 to ignore the ETTL preflashes; if you use Manual mode, there are no preflashes.

That makes perfect sense and I was wondering the same thing earlier (that any flash could trigger the optical sensor on the LP-160). Is it possible, then, to mount the LP-160 on camera and use it as a Master with the 580 as a slave if it were triggered via a green Flash Zebra optical sensor?

Yes. You would not set the remote 580 to Slave mode; you'd just leave it in Normal mode set for Manual power. I assume you want to do it that way to get the more-powerful flash off camera?
And you are absolutely correct that it needs to be the green-base Sonia trigger to work on Canon Speedlites. (They'll also work on other brands, but so will cheaper ones. For the few extra bucks, though, I'd get the green ones just so all that I had would work with all my flashes.)

Yes but your lp160 says its designed to ignor the preflash . If a simple optical trigger doesn't ignor the pre flash then it will fire to early.
The LP-160 has a slave mode to ignore the pre-flash.

Thanks for the tip! It's been a long week, but hopefully will have some time to play with it tomorrow and get better acquainted with my newly acquired lighting gear. Thanks again for your help with this and previous threads.
