If you had only one lens on your OMD or other MF3 rig for walking around which lens would it be?

Depending on where i was going and what I wanted to do, I'd have a 24mm or 35mm equiv prime and an LX5 in a pocket (or the hands of my traveling companion).

Or I'd have a 35-70 equiv f2.8 zoom... and an LX5 in a pocket (or the hands of my traveling companion).

Or I'd have a 80-200 equiv f2.8 prime... and an LX5 in a pocket (or the hands of my traveling companion).

In every case I'd have the LX5.
