Olympus Pen FT
✎ Edit this pageThe Olympus Pen FT was a revolutionary half-frame 35mm SLR camera introduced in 1966, offering the world's first and most successful half-frame SLR system. This innovative camera doubled the number of exposures per roll by using a smaller 18x24mm format, making it extremely economical for photographers. The Pen FT featured through-the-lens metering, interchangeable lenses via the Pen F-mount, and a unique porro-prism viewfinder design that kept the camera remarkably compact. Its high-quality Zuiko lenses delivered exceptional sharpness despite the smaller format, while the camera's precision construction rivaled full-frame SLRs of the era. Popular among photojournalists and travel photographers who valued portability and economy, the Pen FT demonstrated Olympus's innovative approach to camera design and established the foundation for their compact camera philosophy that would later influence the OM system.
