>>3706275If you have good technique you can do it, basically you need to follow the bird as youre taking the photo, rather than keep the camera still and hit the shutter, its like F1 race photos (pic related), if you can pan with the subject, you can effectively reduce their relative motion to the camera, and get sharper shots with less motion blur at lower shutter speeds, you transfer the movement into the background instead. Its harder with an object moving randomly in 3D though.
