FA★ 600mm F4 ED[IF]
16-45mm is understandable, it's not that popular and there's quite a few alternatives.
50-200mm is strange... isn't that a kit lens option? I suppose there's the expensive WR version and the 55-300mm, but 50-200mm is still a nice budget telephoto zoom.
18-250mm is mistake to discontinue... the 18-200s are very popular with Nikon and Canon, so people looking into buying Pentax need this as an option to consider Pentax. In fact this lens should also be a kit lens option
FA* 600mm... well, currently it's made by order only, and the volume sold is probably not enough to justify keeping this going.
