This is a believable K-1000 with a really decent zoom lens. The AT-X series cost quite a lot back in the day. Max aperture has nothing to apologize for either. Filter has been on lens since the first minute of its existence and only came off for the photo. All lens functions are perfect. On the camera itself, the speeds are right on, wind-on is buttery smooth, everything is just as it should be. There is no fault to find at this price. Buyer pays only actual shipping. Enjoy!!
