Guys...I went to the Hara Museum
yesterday to see the Eggleston exhibition. Brilliant stuff. After my viewing, I stopped by in the museum shop and picked up a DVD of Reiner Holzemer's film on the man. You can see a trailer here
You might notice that Eggleston is carrying a Leica, but also that the lens appears to be a Nokton 35/1.2. Here are a couple of screengrabs I took.
OK, not quite so clear, but it sure looks like a Nokton to me!
