Summary
This flat “pancake” Fish-Eye-Takumar 17mm F11 lens has fixed focus, a field of view of 180 degrees, and covers the full 24x36mm format. The diaphragm is a perforated disc with perfectly circular openings. This was the first fisheye lens from Pentax, and also the first fisheye lens to become available in M42 mount. The Takumar 17mm F11 was quickly replaced by the 18mm F11 in 1963.
