konica fとは 意味・読み方・使い方

The Konica F was the first 35 mm SLR camera produced by Konishiroku, released in February, 1960. It featured a built-in light metering system to set the correct exposure. The meter utilized a large selenium cell panel on the front of the viewfinder prism to detect light levels. This type sensor cell generates its own small electrical current, so the metering system does not require a battery. On the other hand, selenium cells are known to degrade over time, losing accuracy or eventually failing. Many cameras and handheld meters relied upon selenium cells at one time, but they were gradually replaced by CdS and other types of cells that require a battery, but tend to give long-term reliability. Between 600 and 1500 total Konica Fs were produced, making it a highly sought-after camera.
