Interesting. I started watching this video a while back, but never made it this far.
One of the things that draws me to shooting LF street photography is its conspicuousness. One of the key reasons the Leica is such a wonderful tool is that you can get in close very easily. On the contrary, the LF camera becomes a unique tool precisely because of its inability to get in close. It announces its presence, and people adjust to its presence; there's absolutely nothing covert about the process.
That's a unique place to occupy as a street photography, and I'm very anxious to go there.
EDIT: JM directly addresses this. Brilliant!
