The photos and condition descriptions take precedence. The Pentax‑110 18mm f/2.8, was introduced in 1979 as a wide-angle lens for the Pentax Auto 110 system. Here are its main features: • Design and Application ・Designed specifically for the Auto 110 system, optimized for the small 110 film format (approx. 13 x 17mm). ・At the time, the 18mm focal length was considered a wide-angle lens equivalent to approximately 35mm in 35mm format, suitable for landscapes and snapshot photography. • Specifications ・Maximum aperture: f/2.8 ・Focal length: 18mm (a bright lens despite its compact design) ・Uses a dedicated bayonet mount, allowing it to be securely attached to the Auto 110 camera body. ・Manual focus design, requiring the user to adjust the focus. • Modern Use ・Today, it can be mounted on modern digital cameras such as Pentax Q and Micro Four Thirds using a dedicated adapter. However, when using an adapter, the crop factor due to the sensor size will affect the actual angle of view and focal length. This lens, despite its small film format, was designed to provide sufficient optical performance within the limited space of the time, and is known for its retro feel and unique depiction. ★ Other/Disclaimer ★ ・Warranty: We will address failures or damage that are clearly unusable by the time you confirm receipt.
