Pentax 6x7 meter needle question!

[gabrielcik]

Hi,

I own a pentax 6x7 and 2 meters...

I had to open and partialy disasemblate both meters (which were sold as dead) for to repair them. The operation was successful, they now both work and seems to be accurate comparing them to my Nikon FM.

These two meters look different from each other inside. One has 2 boards (looking older) and the other one only one on the left.

My question is about the needle.
In the "older meter" the "off point" of the needle is on plus and when switched on it sharply move down to minus.
The main "trouble" is that the needle move after the "minus" when the exposure is very low and so it totally disappear from the meter area (the rectangle box).

My other one has a "off point" on minus and it never goes after the minus - plus limits, it is always visible.

Watching pictures on the net, I saw other meters with "off points" on plus... so i believe this is not a problem... but i would like to know if it is normal that it goes after the minus border or is missing something there.

I hope you understood the point, thanks for your help!
I have pictures if it may help.

Hi,
I would like to know if anybody who has a pentax ttl meter for 6x7 could check the position of the needle when the meter is off. It points to minus or plus.

And if to plus, when it moves the needle can go after the minus limit?

thx!

I don't even see the needle with mine on off. But I don't use the meter much and it now appears to be dead.

mine is at the bottom. It's the more modern version TTL prism.

Hi,

My old meter serial number start with 533. The newer one 552.


Often when the meter seems to be dead there is a problem with the connectors... or simply some cabe disconnected (expecially those that connect the meter to the camera body.
Other times, if you don't see the needle at all could be the inside mirror which reflect the meter inside the viewfinder...
