Why bother with a modern digital when you can have all the fun of shooting with an ancient film camera? I am continually amazed by the number of younger street photographers walking around most world cities with a film camera in their hands. An old Leica, perhaps an M3 or an M2 is the usual camera of choice. But this one is unusual: A 1946 Russian-made Zorki which the proud owner, who lives in West London, has repaired and renovated to look like new.
