In the future, I'd like to travel to Italy. One of the places I want to visit is the Trevi Fountain. I've been told that it's located in a pretty cramped area, and that I'd need a super-wide lens to capture the entire fountain in one image. Anyone with experience taking photos of the Trevi Fountain? And if yes, how wide of a lens would I need for the job? Would 28mm (in equivalent focal length) be wide enough? Or do I need super wide stuff? Thanks!
