For those who might be interested, here is what I'm curently using:

Cameras: Olympus OMD EM-10 mk II, Yashica MAT 124G, Minoltas Hi-Matic 7s, Sigma DP2M

The EM-10 is the interchangable lens camera, I really perfer prime lenses. This is what I have now:
Panasonic/Leica 25mm f1.4 Summilux
Sigma 60mm f2.8 Art
Carl Zeiss Sonnar 85mm f2.8 (in Rollei mount)

Note that Micro 4/3 is a x2 crop factor for the lens. So in 35mm terms, the 25mm f1.4 is really a 50mm normal lens.
