Variants & identification

Variant Mount Years Serial ranges Production
Pen (1959) Half-frame 1959 β€” No figure published for the model; 17 million half-frame Pens of all types were sold by the early 1980s (camera-wiki, citing Olympus)
Pen S (1960) Half-frame 1960 β€” No figure published
  1. The Pen and the Pen S are one page: the same body, the same shutter family and the same 28mm f/3.5 option, with the S adding speeds and a faster lens as an upgrade Olympus sold alongside the original. The f/2.8 Pen S is not a different camera in the way the Pen D, with its 32mm f/1.9 and meter, is.
  2. Olympus's own history gives the 6,000-yen target and the October 1959 launch; the 17 million figure is for every half-frame Pen from 1959 to the early 1980s and no per-model split has ever been published.
  3. The first cameras were not made by Olympus. Sanko-Shoji built them under contract, and those bodies, and the 'Pen Original' assembled by Olympus from Sanko-Shoji parts, have one strap lug where every later Pen has two β€” the only external tell of the first year.
How to tell them apart (expand)
  • A body the size of a cigarette packet with the lens dead centre and the finder above it β€” the shape every half-frame that followed borrowed
  • Thumbwheel advance on the back, frame counter to 72
  • No meter window: the Pen E series has a selenium ring around the lens, the D has a meter cell on the front plate; the Pen and Pen S have neither

Pen (1959):

  • D.Zuiko 28mm f/3.5, four elements in three groups, Tessar-derived
  • Copal leaf shutter with 1/25, 1/50, 1/100, 1/200 and B β€” the four-speed dial is the quickest way to tell a Pen from a Pen S
  • The earliest bodies were built for Olympus by the sub-contractor Sanko-Shoji and carry a single strap lug; Olympus took production in-house within a year

Pen S (1960):

  • Shutter of 1/8, 1/15, 1/30, 1/60, 1/125, 1/250 and B β€” seven settings against the Pen's four
  • Sold with either the 30mm f/2.8 D.Zuiko or the 28mm f/3.5; the f/2.8 is the one collectors mean by 'Pen S'

Where sources disagree

Pen S lens
  • 30mm f/2.8 D.Zuiko (most accounts, and the lens reviewers write about)
  • 28mm f/3.5 β€” a Pen S so fitted existed alongside it (camera-wiki, Wikipedia)

Better supported: Both existed

Not a disagreement about the camera but about what 'Pen S' names. Olympus sold the S with either lens; the faster one is the one the name is remembered for.

What reviewers say

History

The Pen exists because of a number. Olympus gave Maitani Yoshihisa a target of 6,000 yen for a camera an ordinary person could buy, and the only way he found to hit it without a toy lens was to expose half a frame of 35mm film: 18 by 24 millimetres, seventy-two pictures from a cassette of thirty-six, in a body the size of a cigarette packet. It went on sale in October 1959 and Olympus could not build them fast enough β€” the first year’s cameras were made by a sub-contractor, Sanko-Shoji, and carry a single strap lug to prove it.

The camera itself is as plain as its price. A D.Zuiko 28mm f/3.5, four elements in the Tessar pattern, a Copal shutter with four speeds from 1/25 to 1/200, a scale on the lens for focusing and nothing at all for exposure: no meter, no rangefinder, no automation. The Pen S of 1960 kept the body and gave it seven speeds from 1/8 to 1/250 and, in the version people remember, a 30mm f/2.8. Both sold beside each other, and this page treats them as one camera with an upgrade, which is how Olympus sold them.

What followed was a family. The Pen EE of 1961 put a selenium ring around the lens and took every decision away from the photographer; the Pen D of 1962 went the other way with an f/1.9 and a meter; the Pen W of 1964 fitted a 25mm; the Pen F of 1963 made the format into a system SLR. Seventeen million half-frame Pens were sold before the line ended in the early 1980s, and no one has ever published how many of them were the plain Pen that started it.
