What have I done now?



Not one, not two, but THREE Olympus Pen half-frame cameras, obtained off of eBay for $29.50. The first?



An EE, from the 1960s. A fixed-focus lens, surrounded by a selenium "electronic eye" (hence the EE designation) that chooses exposure based on the film speed setting. On to the next...



An EE-S, also from the 1960s, with the added features of a three-position "focusable" lens, two shutter speeds, and threads for filters over just the lens or over the lens and the "eye". And finally...



An EE-S, from the 1970s, maybe even the 1980s. Additions include a flash hot shoe, and a film speed range up to 400.



All three are half-frame, using half a normal 35mm film frame for each exposure, which doubles the exposures on each roll of film. Two of them are loaded with film as I write this, and they seem to be functioning. We'll see...
