The *istD displays very minimal mirror vibration. The two second delay
should be more than adequate for microscope work.

Hi Jens,
I'm thinking of the microscope of course. At high magnifications
vibrations are a serious consideration. Is it possible that a software
change could lift the mirror in advance? I have no idea how these
things are done, but guess that quite a number of operations are
controlled by the program. Of course if it's a mechanical thing, and
it most likely is, nothing can be done. I know next to nothing about
digital cameras but will have to learn fast because I have an
ambitious project in the pipeline.
But is the mirror vibration serious? I've used SLRs with dreadful
clattering mirrors (Alpa Reflex) and shutters that vibrated seriously
and still got decent results with a little care. Of course for very
fussy work I'll still use a dedicated 35mm microscope camera (Wild
MPS51).
Any idea about the flash? I've been searching the web but haven't come
up with anything so far.

Hello Don.
I clever decision IMO.
About the *ist D:
No mirror lock-up. But you can choose between 2 sec and 10 sec self
timer,
which unfortunately doesn't prerelease the mirror (like PZ-1). But it
still
reduces vibration (from you touching the camera).
No important flaws, except maybe:
1) CF card door/CF card removal inconvenient.
2) No instant histogram available (after three clicks it's there)
Not a big deal, really. You'll get used to it.

Emne: Digital finally
Hi all,
I am about to invest -- after all this
time -- in a digital camera. In the past
I have had some really valuable help
from old friends in this group and now
need more.
I'd like to use a Pentax *ist D or its
smaller sibling because I have a decent
collection of Pentax lenses, a macro
setup, and the body would go onto the
microscopes without any need for further
engineering -- that has all been done
for other SLR bodies.
Here are the questions:
Does the camera have mirror lock-up or
some other anti-vibration feature?
Is the cable release an expensive addition?
Will it work with the Vivitar 730AFPK
Autofocus Zoom Flash I have for the MZ50?
Are there any weaknesses that have
emerged over the few years the camera
has been on the market?
I'll be looking for a secondhand body
and if anyone has such a thing I'd be
interested.
Best,
Don
