It is a very good and very unique camera. I've had mine now for over 6 years, and always with relatively low use. Due to its much more advanced features and controls, with WR construction, I bought it to replace my old, likewise low-use K-r, which I gave to friends along with 2 kit lenses, DA 18-55mm II and DA 55-300mm. My main camera then was my K-5 IIs. My K-r and then the K-S2 serve in special roles as my compact, lightweight alternative when I need to carry as light as I can but still having fine quality. The K-S2 turned out to be amazing, even better than I anticipated. I had no awareness then of aperture failure problems.
I got it new from B&H of NYC at an amazingly low price. They might have been recently advised of the soon forthcoming K-70, hence the special low price to clear out their latest batch of stock. My special deal was $508 US WITH the pre-packaged incredibly small DA-L 18-50mm zoom lens, and free shipping. The K-70 was later announced in June of 2016, so their K- S2 stock would be gone to make room for the new K-70. Mine might possibly have been made just in time to not be before December, 2015. I bought it in January of 2016, and B&H are the largest or among the largest camera retailers in the US, moving a tremendous amount of stock.
Initially, the K-S2 was particularly suitable for me on vacations where I would do some extensive shooting while bicycling, or on long walks, or even those at home. I also had bought the HD DA 20-40mm Ltd lens, and for years also had the DA 18-135mm WR, as well as numerous other high quality compact lenses. Then in June of 2017, I acquired the KP, which became my favorite for these activities, so the K-S2 received even less use. But for attending social events, I've found it to be especially adaptive in such circumstances. With the very small DA-L 18-55mm zoom lens, it can fit nicely into a large jacket pocket, or into a small holster belt case I have, and its special selfie-(with-friend) feature works quite well! At the same time, its imaging quality is very fine, so that any more serious photographic opportunities that might be encountered along the way can be addressed with great results. It is even pretty good for handling low light situations, when having to raise ISO. Even though having some top-rated models, I do love my well-featured, high-performing, yet very petite K-S2!
I do happen to have a non-working K200D, as well as a working K100D, which I never use. But I hope my K-S2 keeps on going and I am one of those fortunate K-S2 users who never has to experience ABF.
