I've been taking a bunch of photos of my daughter's soccer games. Some photos come out great. Others, not so much.

Using A55, with Minolta 70-210/4 lens ("beercan"). Generally shooting shutter priority with high shutter speed (>500, often >1000) and F-stop as light will allow, but using ISOs of 800-3200 depending on sky, so generally in the 5.6-11 range. AF-C mode, although that doesn't seem to affect things.

Anyway, here are a couple of pictures. I don't think it's a motion issue - shutter speeds are high enough. Nor does it seem to be a focal plane issue, as the entire picture seems out of focus. Or something else is going wrong. Is it just chromatic aberrance? Something else going on? Any suggested fixes?

Could be sticky aperture blades. What happens is that the aperture does not close fast enough to the value you have set (e.g. to F9). The camera thinks the lens is at F9 and calculates and appropriate shutter speed. In fact, the aperture is wider and therefore too much light gets in and the picture ends up overexposed.

Try pulling back the aperture lever at the back of the lens and observe how quickly the aperture closes down again after letting go of the lever. If that doesn't happen instantly, the aperture blades are sticky.
