I am looking for flashlight electronics (and fitting bulbs) to

asseble a "special purpose" flashlight myself. Is there any

manufacturer known to produce and sell these things?

Today I purchased a Bronica SQ-am with the ae-prism, but I am missing

the correct user manual. I only own the SQ-ai-manual. The functions

are clear, but I still cannot figure out what the small silver

pushbutton in the right left of the motordrive-dail is for. When

pushing it, the camera moves film forwards or backwards, I do not

know which direction. And what does the red LED above the button tell

me? Maybe someone an tell me?

Primarily I am looking for development times for Neopan Acros and

Ilford Perceptol 1:3 or ID-11 1:3. I am also interested in any

recommendations using and developing neopan acros.

I've read an article about the comparison of Tmax 100 and Neopan

Acros which said, that the perfomance was nearly equal. But it said

nothing about Ilford's Delta 100, which I normally use. I never tried

any other B/W-material at that speed, 'cause Delta 100 gave me very

pleasing results, and there is really no reason for me to change, but

anyway: which of these has the best performance?

I recently bought a MF 2/135 Pre-Ai Nikkor which has been converted

to Ai. The diaphragm lever has been shortened about a milimeter, is

this correct? The lens and the diaphragm seen to work very well, but

when turning the lens around its axis or shaking it a little bit,

there is a strange noise comming from the area of the diaphragm which

sounds like a spring or a small metal piece moving and slightly

scratching a metal surface. This is no sound any of my other lenses

make. But I have heard this before on a cheap vivitar lens, that has

been repaired before. Has something in this lens not been attached

correctly, or does someone has any idea of what this could be, maybe

a common problem in these lenses.

Not really an important question, but it interests me somehow: I own

two Nikon F3 and I found a four digits long code printed in black on

black which is right under the lever which is for removing the back

(so it is olny visible after removing it). Does this tell me

something about the camerabody? It seems to have nothing in common

with the serial number.

Does anyone have any experience with this infrared-film? I would like

to try this out for portraits, but since I have to specially order

this film, I would like to know a little bit more about it. AFAIK

skin tones become very dark, when using IR-material, which is an

effect I really like if it suitable for the motive but which I never

reached with ordinary B/W-Films and filters.
