The M5 has always been one my favorites because of the highly sensitive semi-spot meter with a reasonably well defined metering area. Battery issues aside, the reason I had to eventually switch to the M6 and future variants was due to a shift in spectral sensitivity of the M5's CdS cell with age towards longer wavelengths, in other words it became more sensitive to reds and less sensitive to blues. I found this to be true on more than one sample of M5s that I came across. This was not the case with modern silicon blue cells introduced with the M6 where sensitivity was flat across the visible spectrum. It may not be a big issue when shooting B&W film but for narrow latitude slide film, it became problematic. I suppose one could have the meter cell replaced with a new one but I suspect that would not be cheap. I eventually gave up shooting Leica film cameras many years ago because of the added cost and delays in getting quality E6 processing with the market shift to digital.
