[Leica] Leica MC Meters

["Tony Salce" <NadinaTony@bigpond.com>]

Hello All,

I'm new to the list. I aplogise if this question appears basic. I've just
purchased an M3 with an MC meter, which appears to work. I have no idea how
to use it. I have successfully been able to mount it, without scratching the
top plate, but as to its actual usage, I'm a bit lost. It appears to me that
you can only shoot in either an aperture priority or shutter priority
mode.How do you know what aperture you ought set your lens to ?

Also, I do not know whether the honeycomb type screen ought be fully exposed
or do I put the "incident light" attachment that covers the honeycomb screen
over it ? Furthermore there is another little "gadget" in the box that came
with the MC meter. A smallpiece of plastic with two black dots and a black
line. Does anyone know what this is ?

Your replies would be greatly appreciated.

Thank you,

Tony Salce
