The Pen EES is a camera that improved the Pen EE's lens from f/3.5 to f/2.8, making it brighter. Because of this, it changed from a fixed focus to zone focusing. The aperture also automatically adjusts its size based on the brightness, resulting in sharp images. It's compact and easy to hold, allows for worry-free film use, and was high-performing, constantly evolving. *The following adjustments and maintenance were performed: Body: Sterilization cleaning. The body is clean. Finder: Disassembly and cleaning; clear. Exposure: The aperture changes size according to the brightness, so it's functioning correctly. When the exposure is too dark for the camera to handle, a "red tongue" (red warning mark) appears. Lens: Clear. Film Chamber: Replacement of deteriorated light seals.
