Key Features — Olympus Pen F
Half-Frame 35mm Format: Captures 18x24mm frames, yielding up to 72 exposures on a standard 36-exposure roll of 35mm film.
Porro Prism SLR Viewfinder: Through-the-lens optical viewing via a Porro prism design — unusual for a half-frame camera and useful for precise framing.
Olympus Pen F Bayonet Mount: Uses the dedicated Pen F half-frame bayonet mount — not compatible with Olympus OM-mount lenses, which use a different, incompatible mount.
All-Metal Aluminum Body: Aluminum alloy construction provides a durable, solid feel while keeping the camera relatively compact for a half-frame SLR.

Description — Olympus Pen F
The Olympus Pen F is a manual-focus, half-frame 35mm film camera built around an aluminum alloy body measuring 127 x 69.5 x 62.5 mm and weighing 560g. It captures images on a 24x18mm film frame using the half-frame format, squeezing more exposures from each roll of standard 35mm film. The camera uses the Olympus OM lens mount, compatible with OM-mount optics.
Viewing is handled by a Porro prism optical SLR viewfinder, giving a true through-the-lens perspective. Focusing is manual only — there is no autofocus system. Flash shooters will find a PC sync socket with X-sync at all shutter speeds, plus a cold shoe accessory slot for mounting additional gear.
Supported film speeds run from ISO 25 to ISO 400. The body carries no weather sealing and no image stabilization. For film photographers who value a compact, all-metal, manual shooting experience with the distinctive half-frame format, the Olympus Pen F remains a purposeful and well-built option.
