Hi,
I have a Pentax dedicated vivitar flash with TTL capabilities. Does the Z-1P
allow TTL with K and M series lenses? I tried a quick test last night with a
K 35/3.5 and would get the green auto exposure OK light on the flash to come
on only up to F 5.6 even though I was 6 ft away from the
It's always problematic to test TTL flash with no film in the camera.
Since the sensor is measuring light reflected off the film, it's
measuring what would seem to be a reduced amount of light reflecting
off the black pressure plate instead.
I don't think there's any problem using TTL flash

I may be wrong but I do not
TTL is done through off-the-film metering, albeit as a separate
system from the Z-1p (and the Z1, SF1/SF1n, Super Program) camera's
regular light metering system. The LX is the only Pentax camera to
incorporate both TTL metering as well as off-the-film light metering
at the time of exposure

That's totally different from TTL
TTL metering is done off the film. There's a sensor in the mirror box
that points back toward the film plane (on the PZ-1p it's on the right
side of

Brain fart. :-)

Yes, and on the MZ-S the sensor is under the mirror, before the AF

Hey, for
If I am correct, the TTL flash metering of Z-1p can do centre-weighted only
(unlike Nikon where you can choose whatever metering you liked for TTL
flash), similar to Super A/Program. The TTL flash sensor is located on the
side of the mirror box. However, I could be wrong. The manual doesn't

Hey, for years I didn't know how TTL flash worked at all. I posted some
questions on rec.photo.equipment.35mm and got several detailed
answers... *all* of which covered everything *except* the fact that the
camera is metering off the film during the exposure! And, of course,
If flash TTL works the same with the Z-1p as with the LX, (and I think it
does),
your camera is reading severe under exposure with no film, reading the
reflected
light off the pressure plate.
