Subject: [rollei_list] Re: Which Rolleicord
Four months ago, I bought a 'brand new' Rolleiflex 2.8F
Aurum (yes, that
gold plated one with the endangered animal skin covering). I
haven't taken
it out of its box yet (it was still in the corregated box
that came from the
factory). I'm going to wait until Harry finishes with my
Rolleicord and
Rollei 35 before I bog him down with a third camera. I'm
praying that a
selenium meter that hasn't seen light for several decades
will still work.
I still cruise ebay for a good deal on an SL66.

Just being in the dark does no harm to a Selenium cell.
What kills them is excessive heat or exposure to moisture.
The cells are supposed to be sealed but sometimes the seals
break down with age and moisture can get in. The usual
symptom is that the meter becomes non-linear, that is, there
is a progressive error increasing with light intensity. Bad
cells frequently read low by about one stop for bright light
_at the cell_. This is easy to check for meters which have
two ranges with an overlap in between them. A good cell will
give identical readings on both ranges within the scale
error of the meter. A bad cell will give a significantly
lower reading on the low range than the high range.
