I haven't really done much street photography with the Hassy yet, but quite a bit with the Canons. I did find that the Hassy, being a professional camera, and a little slow in working, allowed a bit more interaction with the subject which could be beneficial. In parts of Asia and the middle East people have been very glad to pose or be photographed! Always a variable quantity. In Tienjan China one weekend the grandparents were out with the young children and were quite pleased to introduce them to their first Foreign Devil! One of those (taken with a Canon) did very well in a juried show.
Keep up the good work, hard to get all the dust off of film for scanning! One of the pleasures of digital!
