Thank you for viewing! This lens is from the PENTAX film era. The focal length is 35mm to 80mm, with a zoom ratio of approximately 2.2x. When converted to APS-C, the focal length becomes 52.5mm to 120mm, making it a standard to medium telephoto lens. Although it's an old lens, it rarely has dust inside, clouding of the middle lens element, or balsam separation, making it an excellent lens. Since it was originally designed for full-frame use, utilizing the best optical performance of the central part of the lens with APS-C allows for beautiful images. Because it's a 35-80mm lens, it doesn't produce aberrations like spherical and chromatic aberration, even without using a particularly high-performance lens, allowing for very clean photos. The minimum focusing distance is also 0.4m, so you can get as close as 0.4m at 120mm, allowing for a quasi-macro use. I have prepared many sample photos that show the beautiful images possible with digital photography, so please take a look. The details are sharp, and the colors are good. 【Sample Images】 PENTAX K-S1 + Using this lens 【Condition】 Clouding: None Dust: None Mold: None Rubber: No stickiness or fading Optically clear and a very beautiful item. 【Operation Test】 PENTAX K-50: OK 【Included Items】 Lens body Front cap Rear cap #PENTAX #Pentax #35-80 #35-80 #K-mount #Zoom lens #Old lens
