The first Leicas to sport the Red Dot logo were the Leica M4-2 of 1977, and the Leica R3 SLR of 1976. The Leica M4-2 was based on the M4 form factor and feature set but employed a streamlined production process to reduce manufacturing costs. Specifically, the range/viewfinder was now a modular assembly rather than bench assembled from individual parts. This didn’t materially affect its functionality, but it meant there were fewer adjustments, a fact bemoaned by Leica purists. The M4-2 also added a hot shoe and motor drive compatibility as standard but deleted the mechanical self-timer.
Leica launched the Leica R3 in 1976 as the successor to the Wetzlar made Leicaflex SL2. It was developed in cooperation with Minolta and employed a robust Minolta XE chassis and a jointly designed Copal/Leitz CLS electronic shutter. Initially manufactured in Wetzlar, Germany, Leica R3 production was later moved to the new Leica plant in Portugal. The camera incorporated major modifications to the metering system, offering Leica's traditional selective area metering in addition to integrated (center-weighted) metering. It was also the first Leica SLR to offer automatic exposure, and was complemented (In 1978) by the Leica R3 MOT with an integrated, removable motor winder.
Perhaps ironically, while both the Red Dot Leica M4-2 and the Leica R3 represented compromises to the venerable Leica tradition of in-house bench assembly, both were commercially successful at a very difficult time for the company. Sales of the Leica M5 of 1975, then the latest rangefinder 35, had been dismal, and the previous Lecaflex series had made little or no profit, leaving the company in a precarious financial state. Bottom line: while it would be overstating the case to say that the Red Dot saved Leica, the first Leica cameras to bear that blazing escutcheon assuredly did just that.
Who designed the Red Dot? That information may be buried somewhere in the annals of Wetzlar, whence it originated, but all we can say at this point is that it was probably a German graphic designer. Whoever it was may have been inspired by the stunning Red Dot Leica logo appearing on the cover of the Leica General Catalogue for 1933 and published under the auspices of “Ernst Leitz Wetzlar and London.” It certainly bears a striking resemblance to the current Red Dot except that the red outlined name Leica superimposed in elegantly cursive white letters on the red dot is larger and slightly overhangs the circumference of the dot on both sides.
