The Leica M7, 2002 issued, is the first Leica M to have an electronically
controlled shutter offering aperture priority stepless automatic exposures
control, in addition to the usual manual exposure control familiar from the
Leica M6.
However, the shutter blinds are still of rubberized cloth and remain virtually
silent when operated.
Two mechanically controlled shutter speeds of 1/60 and 1/125 sec. enable the
camera to be used without a battery.
Film speed is set automatically by DX coding, but can be set in automatic mode
by +/- 2 stops.
The selective exposure metering system is similar to that of the M6.
The TTL flash exposure metering is also similar to that of the M6TTL, but in
addition offers a high speed synchronization (HSS) function by which
synchronization speeds as high as 1/1000sec are possible, and flash
synchronization switched to the second shutter blind.
Both these extra flash functions require the Metz 54 MZ3 unit.
There are three different models of the M7 with different viewfinder magnifications and selection of frames for different focal length lenses:
M7 0.85 for 35, 50, 75, 90, and 135mm in black only.
M7 0.72 for 28, 35, 50, 75, 90, and 135mm in black or silver chrome.
M7 0.58 for 24, 28, 35, 75, 90mm in black only.
Externally, apart from the model number on the front, the M7 can be recognized
by the on/off switch coaxial with the shutter release button, the film speed and
exposure compensation dial on the back and the shutter speed dial has "AUTO" in
red engraved between 1000 and B, and two additional slow speeds of 2s and 4s.
For illustration, 2 Leica M7 0.72, in black and in silver chrome with respectives ELMAR-M 2.8/50mm lenses and LEICAVIT-M on their respectives carton boxes and instructions for use booklet.
