Subject: [Leica] luna-pro digital meter question
From: Guy Bennett <guybnt@idt.net>

luggers,

i just picked up a luna-pro digital meter, and am putting it through its
paces. so far i'm very impressed with it; it's small, convenient, and very
easy to use, all of which means i'll be toting it everywhere and getting a
lot of use out of it. as straightforward as it is, however, i do have one
question regarding the way the f-stops are displayed.

on the left of the display window, the f-stops are displayed in big
numbers, and indicated again below in a continuous f-stop scale that reads
from left to right (1  1.4  2  2.8, etc); that is very clear. what is not
clear is: what is the smaller number next to the larger f-stop numbers on
the left-hand side (for example, f 5.6 6 or f 5.6 8)? when i get such
readings, the continuous f-stop scale below may indicate the space between
5.6 and 8, and may even indicate 8, which seems confusing to me. a reading
i just took indicated f 5.6 8 in the large numbers on the left of the
display window, and 8 in the f-stop scale below.

i'm assuming that when i get a reading of f 5.6 6, and on the scale below
the space between 5.6 and 8 is indicated, that means proper exposure is the
half-stop between those two apertures (right?). if that is true, what am i
to make of the f 5.6 8 reading on top, while f 8 is indicated in the scale
below?

sorry for the ot question, but i know that many of you use this meter and
i'm hoping you can help me out.

thanks in advance.
