An AF flash is a flash that has an AF assistence light, like the
Olympus F280 flash has. If the pin-out of this flash equals that of the
OM-4Ti and OM-707 (5 pins), this AF light probably works with the
OM-707. If it equals that of the OM-4 (3 pins) the AF capabilities of
this flash are even more obsolete than those of the F280 (since it
doesn't work with any Olympus camera). Hence the 1/3 price reduction?
How come a brand new flash having no instructions anyway?
To check if this flash has TTL capabilities, try it out on your OM-4.
Camera in Auto mode, film loaded (w/o film TTL flash doesn't work). If
this flash is compatible with the T flashes, as the pin-out suggests,
you should see a flash ready light in the viewfinder, the 1/60 shutter
speed should be marked, the flash should not fire when available light
indicates a faster speed than 1/60, you should see a flash OK light
after the flash fires, even if you hold your hands in front of the
built-in flash sensor (provided this flash also has computer flash
