Subject: Re: Leica CL Metering

The meter in the CL is very sensitive. 

When I first got mine, and even now if I haven't used it for a long while,
the meter takes some getting used to. 

To see if the meter is out of calibration try the folowing:

With either the 90 or 40mm lens meter a grey card covering the full imaging
area at some ISO and note the readings. Now with the same lighting, use a
trusted hand held meter and meter the same card. The readings should be the
same. If not, note the difference.

Since the camera is about 20+ years old, a metering circuit needing a CLA
should not be a concern. Even a meter that is sticky is no great concern.
You may want to contact Leica for a CLA estimate (I think mine was about
$250 several years ago). Use it as a bargaining tool possibly to adjust the
price. For those I have spoken to about this camera, I tell all that figure
a CLA in the price. These cameras seem to be treated with more care than
many others, but also seem to have been less used. This also means most are
ready for a CLA.

The area metered by the CL is not well defined in the manual, but does not
seem to be bottom weighted and reads about 12% of the lens coverage
principally centered about the center with less coverage to the left and
right. Because of this shape, it seems to read (and change readings) more
akin to a reading of less coverage. Also, the meter which reads underexposed
when the needle is above the 'correct exposure' notch is somewhat
disconcerting at first since this condition is opposite of most other
metering systems.

When I contacted Leica re: the 625 issue, I was told the metering would not
be affected by the small difference in voltage. I did a quick comparison
with my camera and found less than about 1/6th stop. Leica did tell me they
could recalibrate the circuit. On my next CLA, I'll have it done to use the
alkaline 625 since my other equip is being recalibrated for this standard
voltage.

Hope this addresses your concerns. The camera and its lenses are for me
about as good as it gets since in 35mm, I use slightly wide angle to short
telephoto focal lengths. The body is substantially smaller than the M series
and with the 40mm attached is one mighty, great, hi quality and long termed
systems made. Good luck.
