Just a short two and a half months ago I purchased my first Leica (M10) and haven't looked back. Never in my lifetime have I made such a sizable purchase AND not feel an ounce of buyer's remorse - the experience has been that good. Even though I am no photographer I do understand that the M10 is like any other tool: it has its primary applications and was designed to do certain things well, not all things well.
So the question is: if you own the M10, do you pair it with another body when you travel? If you do, which one(s) and what are your reasons for doing so?
