Yes, worth it, as I wouldn’t trade my M2-R and 50mm DR for any other camera setup, irrespective of cost, digital or film.
Rangefinders are perfectly suited for my type of photography, and the simplicity of my M2 offers its own set of efficiencies (amidst the admittedly greater conveniences of digital in general).
Moreover, a camera is not just a ‘tool’ for me personally, as the overall photographic process is something I enjoy, including my camera’s unsurpassed tactile pleasure. I don’t think there is one modern Japanese digital camera that offers a film advance that performs better than does my Leica’s.
Of course, I’m not a professional, so I can indulge in such seemingly frivolous intangibles…nostalgia, by the way, NOT being one of them.
Is the M2 technologically dated…sure. So are pianos, guitars, clay, chisels, oil paints, the human voice, ink pens, black & white film, and other ancient tools that are still, nevertheless, wonderfully productive mediums in terms of aesthetics and creativity. And besides, not everyone just wants to press a couple sliders and menu buttons, so we’re gosh darn glad about choice.
Anyway, I reckon I might be using my already antiquated M2 some twenty years down the road; something that I could not confidently say about any current digital camera.
