A simple top-viewfinder and a pentaprism finder were available. The removable pentaprism could be swapped for a waistlevel viewfinder with a pop up magnifier. The meter also works independently of the pentaprism finder, which allows for different viewfinder configurations. Viewing lens uses pentaprism reflex optics for the viewing lens. A proprietary Minolta flash shoe atop the pentaprism allows the use of dedicated Minolta flashes. In 1957, the Asahi Pentax combined the fixed pentaprism and the right-hand thumb wind lever. The camera was narrowly the first Japanese-made pentaprism 35mm SLR. The Nikon F, was delivered since 1962 with various pentaprism metering heads.
