A small group of adults and juveniles were foraging just above the ground during frequent rain showers. They often passed just 1-2m from me but were usually traveling to fast and erratically for the camera to respond. I tried the 7D on various settings but it really struggled to focus on the Swallows. I am still not convinced that it is any better than the 40D. I guess 7 weeks in France and Spain with blue sky and raptors will determine whether its any good or not. Or maybe i just expect to much from it.
