Shot with the Pentax HD Pentax-DA 55-300mm f/4.5-6.3 ED PLM WR RE at 300mm a fantastically responsive lens. I was able to track this aircraft in the flight pattern from when it turned base leg then on to final and directly over my shooting position, most shots were keepers using AF-C which has not always been the case with some of my lens. The PLM drive makes this lens the fastest focusing Pentax produced lens to date, I wish it were faster but at f6.3 its stll great.
