Leica's auto-exposure M — the M7 with aperture-priority auto for film rangefinder photography.
The Leica M7 (0.72, Black) launched in 2002 as the first M rangefinder with aperture-priority auto exposure — a significant practical improvement over the manual-only M6. The 0.72x viewfinder suits 35mm and 50mm lenses.
Aperture-priority auto exposure — set the aperture and the M7 selects the shutter speed automatically. Also provides full manual control. The electronic shutter requires batteries — unlike the fully mechanical MP. 1/1000s to 1s auto, plus bulb.
Leica M mount. Black finish. 0.72x viewfinder. Aperture-priority auto and manual. Electronic shutter — battery required for most speeds (only 1/60 and 1/125 work mechanically). Built-in meter.
Available used at professional to luxury prices. The aperture-priority is a genuine practical improvement over the M6 for everyday film shooting. The electronic shutter dependency on batteries is the trade-off vs the fully mechanical MP. For film M photographers wanting auto exposure.
