Grober: No...a different method is used with "auto" flashes like this which do not communicate with the camera:

With the M8 and FL-36 you can only select "Manual" or "Auto" ("Auto TTL" is disabled) on the flash unit. As Riley says, there is no connection between the camera and the flash unit, save for a trigger contact to fire the beast when you press the shutter button on the M8

I'm selecting "Auto" on the flash, 1/250 shutter speed (max sync speed) on the M8 and using whichever aperture is appropriate for the shot. The flash will tell me if the f number I've selected is too small / large to make a correctly exposed pic.

You have to manually input ISO, the lens focal length and f stop into the flash.

In practice in a darkish room, select 1/250 with f5.6 and virtually every shot (whether bounced or direct) is propely exposed (the flash has a photoreceptor on it whch ensures the exposure is correct). I have taken 1,000's of flash pics this way using canon gear - once set up, very quick and very consistent exposures results.

Slightly different considerations apply to fill flash in sunny conditions (which is going to be great fun with this flash)

Guy: Yes - you input ISO and F stop into the flash unit when it is in "Auto" mode.

Robsteve - M8 will fire flash in Auto mode, but you still have to input correct f stop into flash unit AND make sure shutter speed does not exceed 1/250s (M8 does not appear to default to 1/250s on A, even if flash is in hot shoe and powered up).

Hence much much easier to use M8 in manual mode as described above.

**Can't yet get the light intensity compensation to work as described by Riley..might be disabled when flash used on M8, but I'll play. Not a problem at all, though, just alter F stop on the flash instead
