I had no intention to buy additional film cameras as I found film frustrating once accustomed with the immediacy of a dSLR. But I could not bypass the occasion of buying a perfect condition Olympus OM-30 (also called OM-F) for less than 20 euros. 7 euros later (five LR44 batteries) and a roll of film - I had a photographic gear in working order. I hope to report back soon on the quality of the obtained images.

Edit: Four years later I bought an Olympus OM-1n and an Olympus OM-40. Both provide easier access to manual settings (and are black!).
