The RE is an economy version of the R5 with only manual and aperture priority modes.
The RE is a real workhorse camera and at the time offered a cheaper way of entering the R system because both the R5 and R6 were more expensive. Dates from c. 1990 +/- a few years.
Camera Type : Electronically controlled 35mm Single lens reflex camera with automatic shutter.

Exposure meter: Selective and integral through the lens modes , functions linked to programs . Exposure meter works at full apperture with Leica R-lenses with automatic spring –back diaphragm , and at working aperture with lenses and accesoires without automatic spring-back diaphrahm.
Photocell : Silicon photodiode , protected from stray light in lower part of camera. In selective mode the program selector automaticcally places a condenser lens in the front of the photodiode.
Selective exposure metering : Measuring field 7mm diameter,marked in viewfinder . In automatic shutter programs , press shutter-release button to pressure point to store exposure valeu in memeoryfor up to 30s.
Integral exposure metering : Centre-weighted mean of full-field measurement.
Measuring range of exposure meter : Selective mode from 1 cd/ M² to 125000 cd/ M² at F ¼ i.e to 1/2000 at F22.
Integralmode from 0,25 cd/ M² to 125000 cd/ M² at F1.4 i.e from Ev +1 to +20 for ISO 100 film from 1s at F1.4 to 1/2000 at F22.
