Chandos, fill with this flash indoors with moderate speed film isn't to bad.
If I remember correctly this is an aperture priority flash where you set on
of two or three available apertures and an external sensor on the flash
reads the light bouncing back from the subject in center-weighted way and
quenches the flash when sufficient light is read.

So, take a light reading with shutter speed no higher than 1/50.  Adjust the
shutter aperture combination until one of the available aperture options
works within the shutter speed parameters.  Now, do you want 1/1 flash or
something more subtle?  Shutter is your control over ambient light and
aperture is your control over the flash.  If you want flash to appear less
apparent your shutter/aperture combination should give you an aperture
smaller than the flash tells you is correct.  If you want the flash to
predominate then set a shutter speed higher than ambient light meter
readings would indicate.  Now aren't you glad that your M lets you set
intermediate shutter settings.

If you try this outdoors you will quickly find the 1/50 shutter speed a
limitation.  Read the LUG archives for a really long thread.

This is not nearly as hard as it sounds, try it a few times and it becomes
second nature.  If it doesn't, what was that price for a TTL in Bangkok?
