Hello,
I changed my Sea & Sea flash for a Inon Z240 and went on holiday to the Red Sea and only had troubles with the Inon. I changed for the TTL possibilities but it seems not to work. I asked around and some say that TTL with Inon does not work well. So I am thinking about changing back. Inon instructions are hard to understand.
The correct setting for TTL is according Inon this.

Main Dial => S-TTL

EV Control Dial => TTL (9 o'clock position)

Advanced Cancel Circuit Swit => Press and lock


And I had much advice from fellow photographers and sales people but everybody gave different advice.

So I am thinking about changing back. So please if there are people with good advice, share it.

I don't have inon but from what I understand the manual is about as much use as a chocolate teapot!!!

In general, TTL will not work so well for wide angle, but should do very well with macro. This is what I have found with ike ds 125 strobes and ike housing with TTL. The only times I use TTL is with macro.

Chris,

Are you optically firing your Z240's with your camera's flash or are you using a TTL converter (sea & sea or heinrich) with electrical sync cables?

My wife and I both use TTL with Inon Z240's, she with fiber optics and mine with an electrical converter.
Both systems work great with the Ions, but the flash configuration is different depending on which one you use.

I believe for optical you have the magnet button out.
For wired, I do know you push it in and rotatto lock.

Go to Reef Photo and go to knowlegde site - they have a good Inon instruction sheet

The Advanced Cancel Circuit works only for EA and Manual Mode and only for optical triggered modes!
Ryan from Reef Photo & Video wrote a nice article about the various settings: http://www.reefphoto...i...b&article=7

Hello Elmer,

I am using a TTL converter ( heinrich) with electrical sync cables? Can you tell me what flash setting you use? Itís for macro work so from 20 cm till about 100 cm distance.

Hello Elmer,

Set the left dial to STTL, Set the right dial to TTL and turn the advance cancel circuit off by pushing it down and turning it.

If your exposure is not working out, under or over exposed, with these settings then your camera metering or Heinrich is the problem providing your sync cables are properly connected/intact and the contacts are clean (no silicone lube on the 5 small contacts and the housing bulkhead is setup for TTL).
For macro I recommend setting the camera to spot metering and make sure your subject is in the spot when you take the photo.
Another problem could be the Heinrich's battery, it maybe low and need replacement.
Is your exposure under or over exposed? Is it consistently that way?

Hope this helps,
