This is a tourist destination not a functioning church: as Linda pointed out when she saw the photos, there is metal bar installed across the entrance to the sacristy, so it can't be used for a service.  There were about 50 people crowded in listening to a guide when I first arrived (although they soon left, and I was able to take my photos more easily).
There is another Orthodox church in the centre of Sarajevo (the Serbian Orthodox Church of the Nativity of the Theotokos), but I didn't manage to visit it. There is also a catholice church, a mosque and a synagogue within a stone's throw.
