I'm headed there in a couple of months and contemplating what equipment to take. So far I am leaning toward a pair of rangefinders with 15, 35, 50, 85, and 135mm lenses, plus a Horizon. But I am wondering if I should try to take something with perspective control, which in my case would mean an old press camera like a Speed Graphic. So what I need people to give me a feel for is whether the architecture is tall enough for perspective to be an issue, and if so, whether the streets are narrow enough to need a really wide lens. Otherwise I'll plan on something smaller and simpler in medium format.
