Can Somebody please help me with this question. When I use the af540fgz in studio and set it on manual at what length do I set the zoom on the flash.
Secondly when metering with a incident flash meter. Do I point the dome of the light meter towards the flash or towards the camera position

Personally I would set the flash zoom somewhere near to the zoom length when actually taking the shot and imo you'd generally point the light meter in this situ at the camera position.

You set the zoom on the flash for the angle of coverage required from the flash's point of view.

For example, if you are using a 70mm lens, but have the flash mounted off-camera, let's say at 45 degrees to the subject then the flash zoom would depend how close the flash is to subject (ie if the flash is closer than the camera you probably want a wider zoom setting than 70mm).

Of course, you can try anything - you may want light to spill all over the place, so use a wide angle setting on the flash (irrespective of the camera's focal length). Alternatively you may want a focussed pool of light - so use the longer zoom of the flash.

Personally, I don't bother with a flash meter

Just put everything on fully manual (camera & flash) and take a few test shots - using the LCD & histogram to evaluate 'correct' exposure. Usually I can guess the exposure nearly correct, but normally takes just a couple of minutes to get right!

HTH!
