Digital cameras are in some ways a curse, I come back from Prague often having taken huge numbers of photographs. I take pictures of odd things that catch my eye as we walk around (as it costs nothing to develop you might as well fire away!).
Prague has a large number of camera shops, particularly in the arcades along Wenceselas Square. Here you will find windows stocked with new and old cameras. Many are large format and were made in the days before the wall came down. Most are East German, which means that the lens are usually superb. Having said that I haven’t used my medium format Bronica for five years.
