Got another road racing shot in there.
Just shows that you can take action shots with a Pentax
However there sure is room for improvement in Pentax's AF-C. I took this one with a clear blue sky and plenty of light, but later in the event when it got more overcast I started having problems with AF-C just not performing very well (k20d and Bigma) and the keeper rate dropped significantly. I hope that it was due to poor low light AF performance of the k20d and have since upgraded to a k7. Hopefully the faster AF motor and upgraded AF system will work out better. Otherwise I guess next step would be to try an HSM lens and if that fails... well, I don't even want to think about that
To be fair this must be just about the toughest test for an AF system, when your target comes almost straight at you at 100+ mph.
