Today I was able to test my new Mark IV with a couple Harriers in flight. The Mark IV tracked the birds extremely well.
When photographing birds in flight it is generally best to use Manual Exposure. When shooting in Av or other Semi Auto mode the camera will change exposure depending on backgrounds.
To set your exposure set your Camera in Manual Mode, meter a mid tone scene and set your exposure based on the tones. The other option is just to shoot a couple test shots, check your in camera thumbnail and the histogram and then adjust your exposure. I like to shoot most BIF at a shutter speed of at least 1/1600. The aperture and ISO will need to be adjusted accordingly.
The following photo was taken at : ISO 800, f/4.0, 1/1600

A few more Harriers are on todays phlog post
Nice pic!
Great shot!
