I’m a professional photographer as well and have used and compared many cameras over the years. Yes, there’s a Leica mystique. But, photo quality and experience-wise, nothing comes close to Leica M240 and Leica Q. The color is spectacular and the dynamic range is up there just shy of the best D800s. I’ve used Sony RX1s, A7I, A7S, A7RII, Ricohs, Canons, Nikons, whatever – not the same spectacular end result and color. May be subjective, but for me that’s how it is.
That said, I’ll still use Canon or Nikon dslr body for actual photoshoots that require ultra-fast focus and and for extreme sports. But for the soul, and when backpacking – it’s Leica all the way. For sure.
Plus, with the new Q the focus is pretty much the same speed as Nikon and Canon (if you don’t like the rangefinder options.) I can tell you that because I used it as a backup camera in a shoot with Canon. Same number of pics in the end, 95% in focus. Not trying to be Leica fan boy, just thought I’d share something I learned a long the way that could help some people here, since I’ve been looking for a camera like this for over a decade.
