I've taken my Rolleiflex on the last 3 trips to Europe, and it's a great walkaround camera - flexible, quiet, inoffensive - I pack it with a closeup adapter, little cable release gossen digisix and tiny manfrotto tripod and this ALL fits with some film in a small camera bag - this setup pretty much works for everything (even long exposures of Viking ships in a dark museum - with the little tripod sitting on a seat next to me), and the waist level finder means you're not staring at people and that coupled with the innate charm of Rolleiflexes anyway seems to make people react very favourably to them. (I also drag around a 4x5" in a backpack, but less so in cities, for comfort/security more than anything)

Marc!
