As far as the 40mm-e being in between the 35mm and 50mm, because of the 4/3 sensor, it's really like a cropped 35mm-e. This is because the 40mm-e on 4/3 has the same vertical angle of view as a 35mm-e on a standard 2:3 sensor. For me this means that if I crop to 8x10 for my print, the Panasonic 40mm-e works like a 35mm-e would on say an APS sensor.

There's a fantastic documentary about Mr. Shulman called Visual Acoustics. I was able to see it earlier this year, and it was a great introduction to the man and his work. http://www.juliusshulmanfilm.com/

I've been to the first two (Mary Ellen Mark and Alec Soth), and they've been excellent events. Even the organizers seemed surprised to have gotten Erwitt. Should be fun. Mike, if you had to recommend one currently available Erwitt book for those of us unfamiliar, what would it be?
