It is a great camera for street/urban photography, providing you use 400ASA film.
It has all the advantages of a consumer point-and-shoot camera; namely, for most subjects, it's easy to get a good, well exposed photo with the minimum of fuss.
Unfortunately, despite its "Professional" branding, it retains many of the disadvantages of its smaller/cheaper brothers. Fuji did not redesign the layout of the many buttons to make it easy to manually control more than one variable at a time (exposure, focus, aperture, speed, etc).
Setting the aperture is easy, setting shutter speed slightly harder and setting focus distance quite hard. So if you want to meter on one object, focus on another, and set the aperture/speed, you need very long fingers with an extra joint or two.
That said, the large negatives and quality lens makes for great prints and big enlargements.
