nizo 561 exposure indicator problem

Post by **comradejones** » Sun Oct 07, 2007 5:19 pm

Looking though the viewfinder I cannot see the indicator needle moving across the aperture numbers at the bottom of the viewfinder in either auto or using the button in manual mode, although the lightmeter that controls the autom.B frame rate seems to be working (I point at light, the clicks increase, away and they decrease, etc.) Could it be the light meter batteries are flat? But that shouldn't affect the needle when it's in manual mode, right? Or is it just stuffed??!
Anyone?

There is no button for the for the lightmeter but rather a dial.
The button is to test the lightmeter batteries.
Do you see the needle when turning the dial in manual mode.
No light meter batteries are need when using the dial to manually set the aperture and you should see the needle move across the scale.
The autom. B light sensor is different than the lightmeter.
They don't share the same circuit. Try replacing the lightmeter batteries, but be sure to use the proper "weincell" 1.35v batteries. http://www.weincell.com/

Nope, no sign of needle when I turn it in manual mode. I opened the shutter, locked all the way to 'b' held it to the the light and ran it. Can't see any opening or closing of the aperture when I twist the control dial...

Looks like she's toast. This happened to my Nizo S80.
Thought I'd have some fun so I converted it to a shutterless.

You may wish to remove the side cover(panel with all the dials) and make sure that the exposure dial is making a proper connection link.
Just make sure that all the switches are in the correct original position when you put back the cover.

Thanks for the tip. Hey, do you think it would still work for night time autom.B streaking light, etc. fun??

Absolutely. When nizo meters die, they remain at wide aperture. For night timed exposures the iris is fully open anyway. Just make sure you pull back and lock the shutter lever to B. If you use a hand-held meter, you may even be able to shoot regularly at certain frame rates if they coincide with the f/ stop value that is need for a given lighting condition. There is use for this camera after all.
