The problem with Digital is the regular TTL method relied on reflections off the film (It's actually TTL-OTF), with the exception of the Fuji S2 Pro, no DSLR can do that sort of metering, the sensor's reflectivity is not sufficiently predictable. Hence the reliance on preflashes. Actually, both Canon and Nikon had gone to preflash based metering already (Nikon's multi-sensor TTL and Canon's A-TTL and E-TTL systems all use preflashes) as it's more accurate given the extra information that current CPU equipped lenses can provide to the camera. Good old Auto flash will be more reliable on a DSLR than plain TTL.

Hello Jens,

I can understand what you are wanting here.  For DSLR's everyone has
gone to a pre-flash technique for their TTL metering.  I prefer
regular TTL.  When the ambient light is high and the flash is just a
fill, the pre-flash doesn't seem to cause too many problems.  When the
light is lower and the flash becomes more of a main light, I switch to
an old analog Pentax TTL flash (AF400T, AF280T) and shoot TTL.  I
usually have to set the body compensation to about -2 when I do this.
I am always shooting manual mode at that point so the compensation
only affects the flash output.

I guess what I am saying is that to use any later body than the PZ-1p,
like the *istD, DS, I use two different flash systems.  In both cases
I usually shoot manual mode.

HTH,

Bruce
