Outside of frames, normal lenses, yep, makes sense. Live view, EVF, doesn't. It is not liv(f)e.
Yep. If film Leica is still in regular (not once in a while roll) use it needs backup.
"... good reputation as Leica" is kinda lol these days. The only photog I know who is still using digital Leica RF professionally has backup of the backup.
I have Canon DSLR which was in use by one professional, then after new shutter was sold to another professional and after it came to our home and I took pictures with it . Wow! They looked professional
. And I don't need backup for it.
But Leica RF are nice to go out, go on the trip with. They make you feel nice. While they works...
