Leica M7
Encyclopedia
The Leica M7 is a 35 mm camera by Leica AG introduced in 2002. It is the direct successor to the M6
. The Leica M7 is a departure from previous mechanical designs for the M series.
The Leica M7 introduces auto-exposure in aperture priority mode; you set whatever aperture you wish on the lens manually, and the camera will choose a shutter speed. Full manual is also available. The shutter is electronically controlled, but speeds of 1/60th and 1/125th of a second can be used with purely mechanical means, making the camera usable without batteries. Like the M6 TTL, the M7 features an "off" position on the shutter speed dial (the electronics of the M6 Classic can be switched off by setting the dial to the B position).
The shutter release is redesigned, with several distinct levels of pressure. The first detent locks the exposure reading; the shutter fires after the second detent.
The M7 is also the first Leica to support DX encoding
, using the dial that has been on the back of Leica cameras since the M3. Originally used simply as a reminder of the sensitivity of the film, and then as a setting coupled to the lightmeter starting with the M6, the dial now controls exposure compensation
on the M7.
The M7 features viewfinders with magnifications 0.58, 0.72 (28mm) and 0.85 (35mm). The viewfinder optics are multicoated to reduce flare.
Leica M6
The Leica M6 is a rangefinder camera manufactured by Leica from 1984 to 1998.The M6 combines the silhouette of the Leica M3 with a modern, off-the-shutter light meter with no moving parts and LED arrows in the viewfinder. Informally referred to as the M6 "Classic" to distinguish it from the "M6...

Exposure compensation
Exposure compensation is a technique for adjusting the exposure indicated by a photographic exposure meter, in consideration of factors that may cause the indicated exposure to result in a less-than-optimal image. Factors considered may include unusual lighting distribution, variations within a...
