Overview

The Pentax Fisheye Takumar 6x7 35mm f/4.5 is a lightweight, well-built medium format fisheye with a built-in turret of color filters (yellow, orange, red, clear) for black-and-white shooting. Its 11-element design offers a diagonal field of view claimed at 180°, though in practice it may be closer to 160-170° due to focus breathing. Optical weaknesses include potential flare from lens separation on older copies. The focus ring is precise and handling is excellent, but the front cap may loosen over time. It suits Pentax 6x7 users wanting a fun, versatile wide-angle/fisheye for B&W, though it remains a specialty lens.
