Never mind the mirror/mirrorless debate; why does nearly everyone extol the virtues of film Leicas when the Contax blew them out of the water in every respect except perhaps weight?
Interesting comparison. It is both right and wrong, depending on which side of the coin you choose to look. I have owned all Leica M, R, and Leicaflex cameras at some point. I have also owned all models of Contax SLR's. The only thing I can't compare is Contax rangefinder cameras since I have never owned one. I have also owned the majority of both makers glass, including many of the exotics. Base on that, the following is my opinion.
I believe it comes down to design philosophy. Early on Leica chose the path of extremely high mechanical quality in both their cameras and lenses. The ruggedness of Leica lenses is legendary. I believe their M series cameras hold the high water mark for quality to this day, with the new Fuji mirrorless bodies perhaps coming close. Leica lost some of that edge however, when teaming up with Minolta, just as Contax did when joining with Yashica. Both companies were forced to do it to gain the electronic expertise.
As for their lenses, many of both companies designs were absolutely ingenius and ground breaking. The edge for complexity of design might go to Contax, I believe their 25mm retrofocus design is still considered to be the best ever. Leica, on the other hand, was superb in their execution with few companies to this day matching their combination of build quality and optical quality.
As I said, a lot comes down to design philosophy. Leica, in many of their designs, chose to emphasize image contrast even over pure resolution. This is what gives that "Leica look" to their images, they just pop. Contax chose tonal purity and resolution uber alles, but the complexity of some of their designs and the resulting number of glass surfaces actually held their contrast curve down. As a result, I usually used Leicas for landscape work and Contax and Nikon for portrait work.
This is not dissimilar to audio design. Many speakers use crossover design to emphasize tweeter output. This gives the initial impression of great detail and tends to draw in potential buyers. In the long run however, it is this very feature that tires the listener and drives him to a more neutral design.
Anytime one is chosing between the rarified air of Leica and Contax, there is no wrong choice. There is only personal opinion and the knowledge that history has given a reason for these to be among the finest of choices.
