While it is true that the squeeky wheel gets the most grease, I too would be more than a little pissed if my long awaited Leica camera was defective. Arbitrarily assuming that 10% of the LUG has purchased the M8 and that only a dozen buyers are unsatisfied, that's a failure rate of about 6%. Far too great for a $5000 prestige camera. But why so many complaints about a new digital camera when older Leicas are cherished for their reliability. It's the difference between mechanical and electronic product failure characteristics. If correctly designed and manufactured, mechanical devices fail primarily as a function of wear, usually expressed as the number of duty cycles. Back when the M Leicas were introduced, Leica was proud of the fact that the cameras were designed for 250,000 exposures while competing cameras were only expected to last 150,000 to 200,000 exposures. But parts rub against each other, springs weaken, lubrication wears out and use takes its toll. As these processes take place, performance gradually deteriorates to the point where the user notices it. End of life is reached when parts can no longer be adjusted to bring the camera up to specifications. But, except in a few rare instances (i.e. the camera being dropped on a concrete floor or submerged in salt water), the cameras fail gracefully and present few surprises to the user. Solid state electronic devices, after the initial burn in period, have a long and indeterminate life span. I say indeterminate because individual components tend fail randomly as a function of conditions of operation. The closer to the rated voltage and current limits, the shorter the MTBF. If the unit is designed conservatively and components are operated well within specifications, the electronics can last a long, long time, independent of the number of duty cycles. But when the electronic device fails, it usually does so abruptly. One day it works, the next it stops working. There is no graceful failure here - more like catastrophic. The M8 is positioned between both groups. It has mechanical parts, switches, moving optical elements, focus cams, and shutter. It also has electronics, microprocessor, CCD, LEDs and batteries (which have a limited life based on the number of recharge cycles). The mechanicals may fail gracefully, the electronics catastrophically. Most of the complaints on the LUG are about electronic glitches since the mechanical elements have not had much of a chance to wear out. When I worried about hi tech reliability in aerospace equipment for a living, we had a test and quality control department almost as big as the engineering department. In fact the engineering department usually objected to strenuous test and evaluation procedures on the grounds that no rational person would abuse their precious equipment or operate it outside of its design limits. But it's hard to repair a failure on an unmanned space vehicle a million miles from earth. The equipment was tested in every possible environment and subjected to both physical and electrical abuse. If something broke it was redesigned and fixed. It is apparent that Leica skimped on testing and evaluation before pushing the M8 out the door. It is a camera clearly designed by technicians for technicians. I don't need to run through the litany of problems all of which will be corrected "any time now." They should have been detected and corrected before the cameras were shipped. Apparently Leica marketing hoped that buyers would pay a high entry fee to act as "beta" test evaluators. The only way they could get away with that strategy is to repair and replace malfunctioning equipment immediately, studying the failed equipment to determine its weak spots. Instead broken M8s apparently while away months in Solms and New Jersey. In April my dealer lent me an M8 for a week. I didn't experience any catastrophic failures but the camera did lock up once and required a battery removal for a reset. If you looked closely there was slight evidence of banding and magenta shift and the white balance was a but off. Battery life was much shorter than I am used to on digital cameras. I could live with all this if the pictures were indeed exceptional but they didn't appear to be significantly better than any other high end digital camera (heresy). For me, the joy of using my Leica lenses on a digital RF camera was not worth the purchase price. I returned the camera and reluctantly cancelled my order. I'll wait until the M8.1 or perhaps the M9, hoping that Leica gets it right. Finally I disagree with the philosophy that you show support for a company by buying an inadequate product. In business, as in life, you get what you reward. Hold Leica's feet to the fire and make them deliver the hoped for "perfect" digital M. In the meantime I continue to use my highly reliable, predictable, superb quality M3 cameras with real film. The lenses fit the older cameras just fine. Larry Z
