I used a 70-300 Nikon lens with a D7000 fror this picture

My set up for fine tune is :

AF fine tune ON -

Can someone explain why with the focus point at the head everything is blurry ?

Thank you for your help

Some elements of the shot are sharp...the tree trunk to the right. May have been better if one FP was selected not multiple? I have the same cam and lens so would also be interested in what folks say on this one.

The central tree trunk is in focus but everything else closer or farther away... less so.
Were you expecting the AF system to render ALL of the image points in perfect focus?
Or to choose the bird's head as THE object and focus for it?

"I still prefer the single large cross type sensor in the Nikon N90s or N70. They are fast even by today's standards and I am sure could be made a lot faster with current technology.

The best thing is it never hunts for an AF point and I don't have to worry with setting which AF point to use. I simply point the camera right at what I want to focus on, slightly press the shutter button and then if necessary, recompose.

Simple and elegant. The multiple AF points are a brilliant solution to a non-existant problem and a cause of a real problem."

Here is an article on understanding and operating the AF system:

Looking at the photo it appears to me that most of the focus points are soft and areas farther away (to the right) appear a little sharper. I am curious. Have you tuned your lens to the camera using a tripod, focus target @ 45 degrees, target placed at a distance beyond minimum focusing range, using single AF point (center), widest Aperture, and timed shutter release? I see your default setting is +5 for every lens? My D7000 had a slight back focus (as many have had), and my fine tuning to correct is usually 6 to 8, depending on the lens. Is a single default correction what you really want? If the problem is back focus, would a default +5 not make it worse?

I was expecting that the Hawk head will be in focus, that's was the idea to start with

Thank you all for your answers

If I read the exif data correctly, you were zoomed to 300 and shot at 250 which could leave some shake from not a fast enough shutter speed.

Well , maybe I explain myself wrong , but according to deej I was at 300 and shot at 250 .

So my ISO was at ? I believe if the ISO was higher I will be able to choose a faster speed right ?
Sorry if I look stupid but I try to figutre out what's going on . Maybe you can explain this better then any body else .
On the other hand there is no need to clutter the forum with my mistakes who seems so easy to some .

Let go to the pros and learn from them

Get closer to the subject and use center point focusing and put it on the birds eye.

With so many possibilities for focusing, i.e. tree trunks, limbs, the bird itself, etc. you might achieve correct focus on the bird easier by resorting to a technique that was popular in the 20th century. Of course I am referring to manual focusing. With that said, I also rely on AF most of the time, but when there elements in the scene that could confuse the AF, I try to zoom in on the subject, focus manually, then zoom out as necessary to include as much scene as I intended to shoot. I realize this can take a bit more time, but in some circumstances, can yield better results.
