All were with spot focusing and EV. and the SR was on.
I tried to get the head in focus (and the eyes accordingly) but for some reason the camera was too slow to react.
As you can see, the ISO was quite high, any higher and the image would be too noisy.
I did try AF-C,. AF-S and Manual, but nithing came out right (in manual, my eyes and hand are not the best against AF............

Ok now we're getting somewhere.
one thing I can see possibly is vertical shake causing the focusing sensor to move off image.
I have a lot of hand holding trouble, when shooting long shots, with vertical shake. in an image like the otter, as you move above the subject, the focusing spot is concentrating on something further back. A mono pod really helps here.
Also, some of these look cropped, how big is the otter in the origonal? just a question.
the other point someone made is that you may have pushed all the way through the focus to release the shutter, prior to getting focus.
