The difference a camera makes

I was in London and normally I like to shoot with my Canon 5D III but had a tiny GX7 with me.  I was surprised that the smaller form factor and how much unobtrusive I could be made me talk different photos than I might have taken otherwise.

This photo isn't street photography but friend Ron who I had a quick drink with.  I was interested to see whether the much smaller sensor produced an image comparable to the 5D III and when viewed at a smaller size, it's probably much the same.
