Yes, and of course the system lenses will operate more smoothly and be easier to use but in the case of the Sony NEX for example, the lenses are optically poor. So putting up with the compromises of manual focus and diaphragm will yield better results which is surely preferable. Also you can't get a 90mm for the Fuji (yet) so you could crop from the 60mm, or you could use your (probably superior) Leica 90mm lens. If you use an M8 or M9 you have to manually focus and use the manual diaphragm anyway ;)
