Leica RF is really a simple camera, to use to load (film) and a delight to work..
I taught my daughter, a child then, to use the RF in 30 secs..
I showed two fingers then one while blocking main viewfinder so rf only seen.
Loading a film M2,M3 is so easy. I also get more frames..
Guessing the light, with a Kodak paper guide as was packed with film..
My daughter does occasional pro-work but uses Nikon Digital.
I used SLR for nearly all my Fashion and Advertising work.
My M3 is now 52 years in service..my favorite camera..
Could other cameras and lenses equal or surpass?
Yes! But it wouldn't be as much fun..
