I'm a U4/3 user and contribute to the sister site to this with the same user name. I have a 'scratch' that I really need to do something about. My subconscious is telling me to get a Leica because life is not a dress rehearsal - when you're gone you're gone. However, before I attend to the 'scratch', I have questions to do with handling, rangefinder compared to mirrorless U4/3: speed of use, especially for the street, cos that's what I do 90% + of the time, and questions about choice of lenses (not the choice of focal length, because that's a personal choice, I understand, but looking for advice on the choice available at different focal lengths in terms of speed/value quotient, eg 50mm f2.0 and f1.4 and similarly with the 35mm lens). Do I need to start a new thread to ask, or could someone reading this who is both a Mirrorless and rangefinder user possibly say something regarding use of the M240 compared to U4/3. I fully expect the FF to provide a huge leap in quality, but am I expecting too much?
