day's I finally had the chance to test it.
On a beautiful sunny day I shot out to Intaka Island. From my previous session with the lens I knew that the portrait photo's was sharp and clear. My main objective was to do some Bird In Flight Shots. With my previous equipment I was lucky to get maybe one in a hundred shots in focus. What immediately impressed me was how quick the autofocus was. I shot in AV mode. I had my ISO on 800 and my F stop on F5.6. This gave me a shutter speed of up to 4000. Although my panning skills can definitely improved , I still got about 5 keepers out of every 10 shots. By keepers I mean "In Focus". I started shooting at big water birds in flight. As my confidence grew I started shooting smaller birds. As can be seen by my photos, the smallest bird is a sparrow. Previously I battled to get a Sacred Ibis in focus. What also impressed me about the camera is how well it handles noise. All the flight shots was taken with ISO 800. As can be seen on the photo's the noise is minimal and can be easily cleared up with a noise program.
I for one is very happy with my purchase. I now have some gear that will allow me to constantly produce good Bird Photos.
