With the upcoming launch of the Pentax 17 half-frame camera I decided I would use my Olympus-Pen half-frame camera again. The Olympus-Pen was the first of a line of Olympus half-frame 35mm cameras. The camera was initially released in 1959. The version I have is the original Pen. 

Here are the basic specs of the all manual Olympus-Pen:
  • 35mm Olympus D.Zuiko f/2.8 lens
  • Aperture f/3.5 through f/22
  • Speed B, 1/25, 1/50, 1/100, 1/200
  • Manual focus from a minimum of 2 ft to infinity
  • Range finder with bright half-frame lines in viewfinder
  • Film advance via a thumb wheel on the back of the top plate of the camera
  • Count down exposure dial (manually set to number of images on the roll at the beginning of the roll)
  • Flash sync plug
  • Cold shoe (accessory shoe)
Here is an online manual from

I shot a bulk rolled cartridge of Ilford HP5+ and home developed it with Kodak D-76 at 1+1 for 13 minutes.
