I use the ZX-5N, ZX-L, and Super Program, all with older and newer Pentax lens; They all work (however the Super Program film advance lever has just become inoperative--I will try to ship it to some firm who will repair that) and the sort of image quality I get depends entirely on me. If I can ever return to the sort of image quality I use to have years ago, I will move quickly to the newest Pentax Digital camera. So far I am still stumbling along with sloppy results. I make a lot of mistakes (I blame some of them on my age, 74). I'd like to have an old ME Super, but haven't found one yet.
