Pentax Asahi Super-Takumar f/1.8 55mm Lens for Pentax Screw Mount in Case (Pre-Owned)

The Pentax Asahi Super-Takumar f/1.8 55mm lens is a classic manual focus lens produced by Asahi Optical Co., later known as Pentax. Here's some information about it:

1. Focal Length and Aperture: The lens has a focal length of 55mm, making it a standard prime lens suitable for various types of photography, including portraits, street photography, and general-purpose shooting. It features a maximum aperture of f/1.8, which allows for excellent low-light performance and shallow depth of field effects.

2. Optical Design: The Super-Takumar lens line was known for its optical quality. The 55mm f/1.8 lens typically featured a multi-coated optical design, which helped reduce lens flare and improve contrast and color rendition.

3. Manual Focus: Being a manual focus lens, the Super-Takumar 55mm f/1.8 requires the photographer to manually adjust the focus ring to achieve sharp focus. While this may not be as convenient as autofocus lenses, it allows for precise control over focusing, which can be advantageous in certain situations.

4. Pentax Screw Mount: The lens is designed to be used with cameras that utilize the M42 screw mount, also known as the Pentax screw mount. This mount was widely used in both Pentax cameras and other camera brands during the mid-20th century.

5. Build Quality: The Super-Takumar lenses were known for their solid build quality. The lens body was typically made of metal, providing durability and a reassuring feel in hand. The focusing ring was smooth and well-damped, allowing for precise focusing adjustments.

6. Legacy and Compatibility: While designed for film cameras, the Super-Takumar 55mm f/1.8 lens can also be used with digital cameras via appropriate adapters. However, due to its manual focus nature, using it on modern digital cameras may require additional effort and familiarity with manual focusing techniques.
