Check refunds are possible,
This review is from: Pentax SMC FA28mmF3.2 - 105mmF4.5 AL[IF] Silver Zoom Lens (Accessory)
I have heard good things about this lens. However, if you own a recent Pentax camera (e.g. k-r and k-5) I would make sure that the lens can be returned before buying it.
I bought two copies of this lens, and both had problems focusing on my K-r. The focus won't lock. I had only recently bought the k-r so I was a little concerned the problem was with my camera rather than the lens. Therefore, I took the lens to the shop where I bought my k-r. They allowed me to try the lens on their cameras, and I had the same problem both on the k-r and the k-5.
So either ask if you can try the lens before buying, or check that you can return the lens for a full refund.
(Note: I have tried a number of other old pentax lenses, and haven't had any problems with any other lens, so don't let this review put you off trying other old lenses.)
