BRIGHT LINE VIEW AND RANGE FINDER
The LEICA M-A’s bright-line view and range finder is not only a very
high-quality, large, brilliant and bright viewfinder, it is also a highly
accurate range finder coupled to the lens.
The size of the bright-lines corresponds to an image size of 23 x
35mm (slide format) at the shortest setting distance for each focal
length. At longer distances, the camera records more of the
subject than can be seen in the bright-lines.
The bright line frame is linked to the distance setting to ensure that
parallax - the offset between the lens and the viewfinder axis - is
automatically compensated.
The Leica M-A is equipped with a 0.72x magnifying viewfinder. If
lenses with focal lengths of 28 mm (Elmarit from serial number
2411001 onwards), 35, 50, 75, 90 and 135mm are used, the
associated bright line frame is automatically displayed in the
combinations 28+90mm, 35+135mm, 50+75mm.
In the middle of the viewfinder image is the square distance
metering field, which is brighter than the surrounding image field.
All lenses with focal lengths from 16 to 135mm connect with the
range finder when used on the LEICA M-A.
IMAGE FIELD SELECTOR
The image field selector extends the possibilities of the Leica M-A
viewfinder. This built-in universal viewfinder allows you to display
the image frames that do not belong to the lens currently being
used at any time. You can then see immediately if, for
compositional reasons, it would be better to photograph the
relevant subject using a different focal length.
If the lever is rotated outwards, i.e. away from the lens, the image
field limits for 35 and 135mm focal length are shown.
If the lever is moved to its vertical central position, the image field
limits for the focal lengths 50 and 75mm are shown.
If the lever is moved inwards, i.e. towards the lens, the image field
limits for 28 and 90mm focal length are shown.
A Bright line frame
B Actual image field
Set to 0.7m: The film captures approximately one
frame width less.
Set to 2m: The film captures exactly the image field
shown by the inner edges of the bright
line frame.
Set to infinity: The film captures around 1 and 4
(vertical and horizontal respectively)
frame widths more.
