on the shutter speed dial. As the slowest shutter
speed available on the dial is only 1s, exact meter-
ing is also no longer possible. The correct shutter
speed can therefore be obtained only by conver-
sion or from this diagram.
By contrast, with the aperture priority mode, the
LEICA M7 automatically calculates shutter speeds
up to 32s, so that in the example highlighted,
every aperture of the lens could be used.
Metering fields in the viewfinder
(see also pp. 104/105)
The metering field covers approx. 23% of the
viewfinder image for the lens being used.
However, the following reference value applies to
all lens focal lengths:
The diameter of the circular metering field is
approx. 2/3 of the short side of the applicable
bright-line frame. This also applies to lenses with
viewfinder attachments, such as the LEICA
ELMARIT-M 135mm f/2.8.
