Before the "digital" revolution, I replaced the focusing screen on my ZX-7 with a focusing screen from the ZX-M based on information from the pdml. I called Pentax in Colorado and ordered the ZX-M focusing screen. I think the screen cost around $5 plus shipping at that time, and so I bought two, planning to also put it in the PZ-1P.
I never did put it in the PZ-1P (now sold). I have always wanted a split image focusing screen in my *istD, and so a few weeks ago, I took the second screen and sanded it down to the size of the *istD screen. The screen is made of some type of plastic material. Using a piece of sand paper on a flat surface and run the edge of the screen across the sand paper, it took less than 30 mintes to sand it to the correct size. I didn't compare the thickness, but I had no problem fitting it inside the *istD. I have been too busy to do any testing but visually it seems to work fine when compared with the autofocus confirmation. The focusing screen can be scratched easily and so be very careful if you want to try the same. --- Tomasz Machnik <[EMAIL PROTECTED]> wrote: > > > Don Sanderson wrote: > > Since the image is formed on the _top_ surface of > the screen, > > thickness is not critical. > > That's right, I am just not sure if M series screens > are thin enough to > fit the tiny metal frame in DS. > > The only donor I have handy at the moment is a P30, > unfortunately > removing the screen from it seems to take few hours > or a hammer. > Actually, I have both time and hammer available, so > if someone could > confirm that it's screen is _about_ the same > thickness as the one in DS, > I can present a nice report later today, perhaps > featuring a hammer and > (dead) body. > > cheers > Tomasz > > __________________________________________________ Do You Yahoo!?
