In the flash family, "auto" means that the flash will compensate for distance/subject brightness. You do not have to manually use guide numbers to determine the aperture to use. You do not have to manually set the camera to the synch speed.

When the description does not include the letters TTL, then the flash uses its own sensor to control the output of the flash.

I hope this clears up the confusion.
Very detailed explanation of the use of the flash - I love it for a diff reason.

Also my apology to Busiko as well .

I was referring to the question of the OP (re k200d) and the flash can be considered as 'auto' particularly in relation to some of late models of film cameras and its use as a standalone unit.

Hey we all learn from other forum members

Hello Daniel. I'm glad that the light came over that matter. And I see no need for apologies.

Hi Geoff, the same applies to the AF200S flash, Auto or Manual will do. It will work fine, although with less Power (=shorter distance/wider aperture) , and check that the shoe voltage is no higher that 10Volts which I believe is OK.

With a voltmeter, it should read around 7.5V between the side contact(-) and center contact(+). The AF200s should be OK I presume. But if you have the chance confirm before attaching it to the camera.

Yes, every thing below 7~8 volts is safe. If you get remote triggers for them, you can use all at once and play with Lighting and shadows.
Look here for great info on Flash Lighting.
