beaulieu4008 exposure settings problem

Post by peterson »

Hi everyone,
I have a problem with the auto/manual lens aperture settings on my beaulieu4008ZM..
..after recelling the battery container (i have downloaded many advices from this forum) of this camera that I bought on ebay lately..hope I made it right (7,2V for motors and 3,6V for the reglomatic system)

my problem: when I take the reading in auto mode, the pointer in viewfinder always stops above the notch (the aperture ring moves and everything seems to work fine) - the system reflect the light just fine..
..but when I want to get the pointer between the notch (like manual says)to get the proper exposed image I must close the aperture about 3 stops!!
..I will have to wait till my test shots come back from lab to see what setting is right in this case?auto(above the notch) or manual (in between).

where is the mistake?! this could be a stupid question for you guys, but I need some help!!
The problem could be the reglomatic system voltage - I had similar problem with other camera after loading stronger batteries to the nizos lightmeter...

the camera has its own angenieux zoom lens

..thanx for help and sorry for my masa Bob english

Well, many possible causes. I managed to "repair" all my beaulieus with simple cleaning of the main switch, and that's what I'd suggest in your case. too.

- how is the meter working in manual mode?
- how did it work before the recelling?
have fun!

It didn´t work at all..the battery was completely dead, coroded and it was very difficult to remove it. When I finally did I have made a "dummy socket" of it..the motors (zoom, film transport) ran well.
The reglomatic system seems to move kind of slow to me (the ring on the lens) but I have never seen 100% shaped beaulieu working :(
..when I take a reading in AUTO mode, the ring(aperture) starts to adjust the stops..from open 1,9 to position when the needle is above the notch..this may take 15seconds..
there is no problem to adjust the aperture manual mode...but I don´t know which reading is correct..within or above..
when I try to take the reading with another camera(with film and same speed adjusted) it seems that the auto is almost fine and just the needle settles at wrong place (the lenses are 1,9 and 1,8 -this could make the difference?)..don´t have a lightmeter either..
..poor amateur.. :oops:

did you mean the Manuel/Auto/Test switch?
thanx for trying to help..

A lightmeter would be indeed helpful!

The needle might be out of whack, but the setting still can be fine. If you don't have a lightmeter, a test roll will be the only way to tell.

If you set the auto/manual/test switch to "manual", you have to adjust it manually. Try it, and see if the result is the same.

You should also set in maunal mode, and then immediately turn the switch then to auto mode. If the readings are the same, the switch should be OK.

The reglomatic is way to slow however. It doesn't take a sec on mine to go from one extreme to the other. Have you double checked the voltage?
have fun!

I ´ve shot some tests yesterday..desperately awaiting the results - I made some notes, used same light and scene ofcourse...
..after switching ffrom manuel to auto the readings are the same, when I still expect the wrong needle position being "my" right!
I will try to double check the voltage again (with some volmeter) - i was just counting the cells and making the adviced connections and circuit.
