Overall (and this is not to say that there are not any pre-A gems - which there are - and is not to say that there are not any post-A gems - which there are), I also tend to think that "the A series is the high-water mark of Pentax optics" (although this is also not to say that every A lens is a gem - which is not the truth, either). This is to say that, if I had to restrict my lens choices to just one "era" - K, M/M*, A/A*, F/F*, or FA/FA* - I'd choose the A/A* "era" without question. Fred
