Last week I decided it was finally time to move into the digital age with respect to photography. My ZX-5n has served me well, but I found that over the past few years I've been mostly just scanning my pictures anyway, and it made sense to just eliminate that step.

Overall I'm more than pleased with the camera.  Its image quality is
fantastic, ease of use is great too, and so on.  But there is one issue
that has me perplexed.

When I use the camera's built-in flash, particularly with faster lenses
and/or at closer ranges, the pictures come out anywhere from moderately
overexposed to 99% burned out from severe overexposure.

Let's take, for example, the case of the SMC-Pentax FA 50mm f/1.4.
Shooting at a distance of five feet, at ISO equivilancy of 200, in fully
automatic (smart picture) mode, the frame will come out completely
burned out.  The camera is choosing settings of 1/60th and f/2.8.
Anybody with any understanding of photography will know that a
guide-number 15 flash, at a range of 5', with ISO200, shouldn't be
shooting at f/2.8, but rather somewhere more in the neighborhood of f/11.

This problem persists, with slightly less severity, with other lenses
too.  For example, with the SMC-Pentax DA 18-55 f/3.5-5.6, at 55mm, the
camera leaves the lens wide open (f/5.6) for the same shot, and doesn't
stop it down at all.

I even tried setting the flash's EV to -2 just to get it to underexpose
the shots.  No improvement.

Now here's the crazy part.  When I attach my trusty, tried and proven
AF330-FTZ flash instead of using Pentax's built-in flash, the shots come
out wonderfully exposed.

This is a problem that I never faced with my ZX-5n.  It almost seems as
though the built-in flash is NOT benefiting from TTL.

I'm hoping someone else who has encountered this might have a suggestion
as to how to correct the situation without resorting to dropping into
Aperture Priority mode every time I take a shot with the built-in flash.
