It's seriously expensive, it's manual focus only, it has very few menu options, you have to remove the bottom plate to access the card and battery and quite often the lens blocks the viewfinder. And yet I love my Leica M10. It's possibly (probably!) irrational and there's no doubt that it's very poor value for money, but I actually do create better images with it. Why?
I'm not the fastest photographer in the world. I take my time. I focus and then I focus again. I check aperture, shutter speed and composition and only press the shutter when I'm happy with what I see. And the M10 is a pretty slow camera, so we're in sync about that.
But it's been my camera of choice for weeks now. The reason is that I'm fed up with the endless nonsense claimed about cameras, the complications in using them that require hundreds of pages in manuals and tutorial videos, the size, the polycarbonate bodies and above all the endless bickering about about which camera and / or lens is the best. The M10 has no AF points as it's manual focus only and only one video omission. It doesn't have it! It's for shooting stills only and that suits me fine. It has a very pared down menu, limited specifications and no nonsense. I have to use my accumulated photographic experience to get the best out of it and each time I press the shutter it's an event.
Above is the three lens kit I've been using recently. 7artisans 28mm f/1.4 (on the right with a Voigtlander lens hood and cap on it), Voigtlander Nokton 50mm f/1.1 (on the left) and a Leica 90mm Summicron 90mm f/2 (on the camera). Fast lenses, so lots of bokeh pix!!
Not normally my thing but I couldn't resist.
So the Leica M10, old school and proud of it. Expensive, limited specs, probably the worst value for money of any camera that I've ever used, but more fun than a barrel of frogs!! If you don't understand the myth of a Leica M camera, try to get your hands on one and see if you are not overcome with a desire to go out and create some art. I can still remember the experience of picking one up for the first time (An M8) and feeling that now I was a 'proper' photographer. And yes that's pretentious BS BUT, don't knock it until you try it.
