The weather was perfect for the 25th Annual Wings Over Houston Air Show this weekend. Crowds were huge partly because of the weather and also because the Navy flying team the Blue Angels were performing. It's been a while since they've flown at the air show. I've been tweaking my focus modes on my camera lately, really trying to learn what's best for a given situation. Today it was dynamic area focus with closest subject priority, and that really seemed to work well. My percent of keepers (as far as focus) was as high as it's been in recent air show memory. The image above was shot at 1/1000 sec, shutter priority, f/5 with my 300 f/4 lens; I just did a little cropping and sharpening in Photoshop. That 300 f/4 really is a perfect lens for air shows -- sharp, responsive, and light weight.
