I used to run around with Leica R8's, one with a 35 and one with a 50. Why? Because I didn't have to change lenses, they interface is the same and it just makes it easy to concentrate on the photos. I no longer have them but was very close to buying a second F3HP to go with my other one. In the end I got an F5 simply because I just wanted an AF body. In hindsight I should probably have got an F3 because now I keep going back and forth between the two...do I want the big fast one or do I want the small(ish) one with the great viewfinder? Decisions decisions.
