Some of my friends are adding to their existing camera (Nikon) system with smaller and lighter NEX 7 or Fuji X1 Pro kits. The argument smaller, lighter etc. I have been thinking about this for a bit. I find that I am quite happy with the d800e and I have a known quantity inm my lenses that I have zero complaints with. So I was thinking what if they came out with a rangefinder, with 36Mp, decent IQ low light ISO capability easy to adapt lens interchangeability with my existing glass, would I purchase a rangefinder? I like RF for a lot of things and I like the idea of smaller and lighter. I would save a pound in the camera, figuring one pound body as opposed to two pounds. But then that is it. Most of my lenses are manual primes and I am not going to get better nor lighter. And the one thing that I really like is an ultrawide and that is a bear to get a good 20mm, I like what I have but no one would say it is a lightweight lens. So for me the one pound savings is not a compelling argument.
But, if their was a an RF, full frame, big MP, and smooth IQ AND a D3s like low light capability and it took my lenses, then I would seriously look at it.
But I cannot imagine that my wants would translate into a bigger market for any of these manufacturers and so we get what we get.
But it looks like big changes are coming in the market and so who knows? Joe
