Jimmy Dovholt is based in Stockholm, Sweden, and have been shooting for some time now. Event though he alters between different cameras all photos are shot with the same focal length.
I have tried lots of different lenses and focal views but always come back to ~28mm. For me that is the perfect lens.
As for flash work, he usually bangs straight on his subject but smooth the harsh shadows out with slow shutter speed and underexposed flash output.
