Help! Help! I am a new Pacemaker speed graphic user
31/4´´x41/4´´) and have many questions. Who
can answer
me some of them? ( I know the film size problem)
1, How works my selftimer? I see nothing what can be
moved or switched. (Supermatic X shutter)
2, I have a switch that says front, back and Trip. What
means Trip?
3, Is there anyone who can send me a Instruction manual
for the Pacemaker Graphic cameras ( Speed and Crown)?
4, Have the pacemakers 4x5 and the 3x4 same size of the
lensboard?
5, What size is the illumination circle of my
127mm/4.7 Ektar and which aperture is the sharpest? (I
am crazy for sharpness and to poor to buy Hasselblad.
That's why I am trying large format)
6, How and with what can I clean my ground glass? ( It
has some fingerprint grease on)
7, What is the longest lens I can use on my Pacemaker
Speedgrphic 3x4?
Which long lenses are economic in price and good? (I
know the barrel possibility)
8, Is there any possibility to adapt a 4x5 rollfilm
holder to my 3x4 Graflok back? But I still like to do
ground glass composition. So it must work like a sheet
film holder. Which one and which is the cheapest that
wood be working good? Is it hard to do?
9, How sharp is the WF Ektar 80mm/6,3 , the Raptar WA
90mm/6.3 or the Optar WA 90mm/6.3. I red that this
lenses must be stopped down considerably to equal in
sharpness to the general Purpose Tessar lenses. Is this
true? How much must they stopped down? How good are
they? Which one is the best? Are this the most economic
WA lenses and are they hard to find?
10, Why has the bellows lens board unit so a big play
in the metal rails? With the infinity stops its easy to
fix the unit parallel to the film plane but without
them it is hard to measure parallelism. Is there any
possibility to fix this problem?
11, Is there a big problem with sheet film holders and
dust particles because I have to cut down my film
sheets (3x4)? Which is the best way to do this?
