Aberoni: RX1 definitely!
RX1 is a dream camera, not those 'just another good camera' on the list.
Agree, not fair! Surely not honest and independent results!
If this mount is vital, there will be good to excellent lenses for this mount, and of course, less dimentions and weight. All other APS-C or FF lenses can be for fun, not for every day use.
My very first 1,5 month now with NEX-7 kit and E-mount 24F1,8Z I can easily say, that buy'ing NEX-7 roughly means you are switching to E-mount!
