I have an M8.2 that I have had for about a year. I point it at something, I frame it and press the shutter button. Often the photo is mechanically good, i. e., detail, tonality and so on. That's good. Do I prefer it over other cameras for image? Yes. I have a very old, 20+ years, Sony DSC-S70, with, I assume, a CCD sensor. Regardless it gives great images, and this is a camera that is way past it's double overtime. It should not even work! This thread has opinions that digital will not last that long. Perhaps Leicas will not but this old Sony is humming right along.
There is so much irrelevant and unsubstantiated conjecture in this thread about longevity, whether the camera will ever be a classic and so on. If you can control the future you can determine whether or not this camera will become a classic. And chat about how it is fragile. Best cameras made, Leica. Yeah. Regardless, while yours may be crap I am happy with mine, warts and all. If it breaks, fix it. If you cannot fix it get another. This is not rocket surgery. If I can figure it out I know most of this board, if not all, can, too.
Here is an image I have already posted. I defy anyone to tell me that the image was not well-prepared by the camera and lens. You may be unimpressed with the content, that's fine. But to complain that the image is faulty is off the mark
in my opinion.
