Automatic Flash means that the exposure is regulated by a sensor built 
into the flash unit itself. In other words, when the flash unit has 
measured enough light for the stop indicated in its auto exposure 
chart, it quenches the flash. TTL on the other hand is controlled by 
the camera. When the camera's meter has measured an adequate amount of 
light for the stop it is set at, it quenches the light. Generally, TTL 
is more accurate than automatic flash.

Ok, question time...

Can someone explain to me just what the difference between TTL and 
Automatic
flash is?

And whilst you guys figure that out, I am off to get some beauty 
sleep, it
is exactly 2.54am here, and my kids need to be up for school in like 3
hours!

I have problems with the digital Metz 40MZ-2 and SCA3701 adapter.
On automatic it works fine, on TTL it doesn't.
Can it be run as analogue TTL?
For the record, I have always felt that flash metering was one of
Pentax's weak points.
My Metz 60 on automatic is accurate to within 1/10th of a stop at
what I consider normal flash range. My LX is no where near that
accurate, when it decides that it will fire a flash. The istD seems a
bit less accurate than the LX on TTL auto, but it has a PC socket,
which seems a rarity in these times.
