Auto flash shooting

Procedure

Slide the Power switch to (ON).

Set the mode dial to (AUTO).

Confirm that the subject is within the effective
flash range and the ready lamp is lit, and take a
picture.

The correct flash output is obtained in P-TTL

auto mode only when the flash unit is used with
auto-focus lenses.

Set the lens aperture to the position A in P-
TTL Auto mode

When the lens you use is equipped with the lens
aperture ring, set the position of the ring to A (You do
not need to do this for the DA or FAJ lens). Otherwise,
the flash unit cannot function in P-TTL Auto mode.
When you use the cameras that support both P-TTL
and TTL modes (*ist DS2, *ist DS, *ist D) , if the
aperture of the lens is in a position other than A, you can
shoot in TTL Auto flash mode. Be aware that for the
cameras that only support P-TTL Auto flash, the flash
unit does not adjust the flash output but discharges at
full output, if the aperture of the lens is in a position
other than A.

About TTL Auto flash mode

With single lens reflex cameras (film cameras) other
than PENTAX digital single lens reflex cameras, you
can perform auto flash shooting if they support TTL
Auto. (However, the 645 format cameras before SF
series and of the early type do not support the TTL
Auto)
