well, the fact is I had to crop almost 50% of the RAW to get that, tweaking post prod don't make it look too low rez but it is truly^^
In this exact situation I needed twice the focal length to work on a sharp source...

Because I believe there are plenty of good quality Pentax glass that covers the 200mm range and that would have been suitable for such shots. DA* 200mm. DA* 60-250mm. DA* 300mm. DFA 150-450mm. DFA* 70-200mm. Oh, and if those are too expansive, the HD 55-300mm stopped down to f8 should also provide great IQ.
edit : ok, so it seems like I did misunderstood the OP. I guess he is complaining about the fact that it had not the lens readily available with him to capture the moment. Anyhow, the shot is quite nice imo.
1. yes my budget is too low to buy such lenses (the DAs you enumerate)
2. yes I let my only decent 70-210mm at home (tokina SD II)
I'm waiting for a Kiron zoom next week, bought it cheap from Belgium, lucky : it will be a gem, unlucky : crap IQ, it looks virtually as being a good model in mint condition, but this is still virtual... There is a shop not far where they have several great SMC in K or KA mount, the pro is the guy lets me test the lens deeply before buying, the cons is the price is almost the price I had my K200D.
For me, price <> quality, my best lens atm is a Cosina 24mm close focusing (you can macro and wide angle), it's a gem and I got it for parts at 10 euro (approx. 13$), took me 2h to fix it

not really but in this exact situation, weather conditions already lows sharpness + the AA filter + the crop makes it hard to get a sharp not too noisy photo. I had for 1 afternoon a Vivitar serie 1 70-210mm (kiron) tank with the 67mm (or 72) filter thread and yes, with such a lens you really get sharp photos with sharp infinite even in these conditions, see :
this is what I call an HD zoom^^ unfortunately, this model I tested had a mechanical issue with hard points on the one-touch ring, but I now regret not too have bought it (the seller was asking 50 euro) as it was in perfect optical condition.
