He used the same model of camera is I do:
Voigtländer Bergheil DeLuxe Green by
A.Sundell, on Flickr
He used a tripod, set the camera up for long long shutter speeds and had his assistant holding a magnesium flash. His work is great and creative but the fact is still that he didn't use "set it f8-16, zone focus and walk around and shoot", which was what was being discussed.
I have no problem with using other methods of shooting (or else I would not have gotten the folders) to try to be creative with the limitations, but people getting the "sunny16 and then zone focus and walk around" everytime as an answer when bringing up how to do street photography when it's not really workable for everyone is kind of annoying.
