Thank you for viewing. This is an offering for the "FA 31mm F1.8 AL Limited," a particularly popular lens from Pentax's Limited series. It's a high-quality single-focus lens with excellent descriptive power and beautiful bokeh. [Appearance] While there are some minor scratches and scuffs, it's in overall very beautiful condition. The quality of the texture is also maintained. [Optics] There is a small amount of mold on the middle element that does not affect the photos, and I was able to take beautiful pictures without any problems. [Operation] The AF operation is smooth, and the functionality is good. [Included Items] Everything shown in the photos. As this is a one-of-a-kind item, please consider purchasing it as soon as possible if you are looking for it. Size... Pentax K mount Size... Pentax Q mount
