This is the PENTAX-FA 50mm F1.4, an AF prime lens from Pentax. ☆ Tested and confirmed to take pictures. ☆ All functions have been checked and confirmed to be working. ☆ Includes genuine front and rear caps. ◎ Regarding the exterior, it is a used item, so there may be some minor scratches due to storage, but there are no noticeable damages that would affect operation. ◎ Regarding the optics, due to the age of the product, there may be very fine dust or particles inside the lens, but this does not affect the image quality. I believe the condition is good.
