Whilst I still use my three film M`s I saw nothing in the M experience (for me) which would cause me to continue with it into the digital age .
That together with the fact that I now tend to shoot action stuff makes an RF kind of redundant for my day to day use .
I now use an SL2s and CL .
I can , and do, use my M lenses on both and much prefer focusing them through the EVF either using peak or just off the screen.
Interesting that Godfrey is happy with his 5mp output .
I use my CL primes on my full frame SL2s ,which gives me "only" 10 /12 mp and I`m happy too .
LOL! Yes, I'm quite happy with the 5Mpixel output of my E-1 ... It has produced photographs that I've printed to 20x24 inch for exhibition that I've won recognition with. Of course, I'm even happier with the 24Mpixel quality of my Leica CL, and 40Mpixel quality of my Leica M10 Monochrom, never mind the 50Mpixel quality of my Hasselblad 907x. They're all superior performers to the ancient E-1, which does not diminish the quality of the E-1 by one bit.
If you bought the E-1 with it's 5Mpixel image quality and found that sufficiently high resolution, and the sensitivity, imaging qualities, and lenses work for your shooting needs even today, nearly 20 years later, the notion of "planned obsolescence" of the E-1 is irrelevant. And the same goes for any other digital camera: if what you bought worked well for the needs you had, and those needs haven't changed, just keep using what you have and save yourself a boatload of money.
I've owned M9, M-P 240, M-D 262, and M10-M digital Leica M cameras, and probably a dozen or so film Ms over the years. (Never mind all the other cameras I've owned and used over the many years I've been doing Photography...) They're all stunningly good cameras, do the job I wanted when I bought them, and any of them (with the exception of the M9) would have lasted as long as I cared to keep shooting with it, churning out brilliant photos all the time. None of them have required even a single service. The M9 was the one exception because of the sensor problem which showed up 3.5 years after I bought it, and I chose not to update the sensor but to move on to the M-P 240 instead. My interests and needs changed along the way, that's all, and that has nothing to do with the lifespan or durability of the cameras. I have no reason to think that my new M10-M will be any less durable or last any shorter time than my E-1. I can only hope that I last as long, because I'm no longer as young as I was when I bought the E-1...
