I took this photo at the recetn Williamtown Air Show. Lens used was an EF 75-300mm, What I would like some help with is the sharpness of the photo. I have already used an unsharp mask on the image but it is still too soft for my liking. Any suggestions on how I can improve my focus ability for future photos? Any hints are appreciated. The image was taken hand held whilst trying a panning technique, AI Servo mode utilised with Evalutive Matrix focus turned on.
