My photography reflects my vision of life. I like to think that I have a clear vision. I throw away out of focus photos, but if a photo of a duck has a major part of it's anatomy in focus and the rest is motion blur, then I find that acceptable. On the other hand, if the photo is completely out of focus, then I take that to be a missed shot. Most hummingbird shots has motion blur in the wings because it takes specialized lighting to get the motion blur out of the wings and most photographers (including pros) do not have the money for the specialized lighting. I try to record Nature as it is found, not with a distorted view. I guess that I am more of a Natural History photographer than a Nature photographer although not too long ago, they were one and the same. Just my opinion.
