Well I just happen to be a old school photographer with limited knowledge of digital photography I still work within the confines of old fashioned basic photography rules that have served me well over 45 year career! However I am still learning about digital photography even us old guys can learn stuff everyday

I see you used a bean bag rest but was wondering if you used a remote shutter release or delayed shutter release, it may have helped at 500mm.

Download picture and hit the '+' symbol to enlarge it. There is evidence of camera shake.

The near side of the image (bottom right) seems to be the focus point. The grass in this area is sharper. The bird strains the depth of field, and is somewhat unfocused. You might look up how to do a reset on the camera and try that.
Further, the image is about a stop underexposed.

Problem discovered. You need to use a tripod or bean bag and will need to use a remote shutter release or use the built in self timer. Setting your camera on your arm allows the motion that is showing up in this shot.
Then, you will need to work on the exposure, as with many previous comments, this shot is under exposed. If you can't get enough light with changing your shutter speed and f-stop, then you will need to increase your ISO.

The lighting is bad in this area and not providing enough contrast or interest. At 500mm zoom, any amount of movement will show. Raise your ISO, place camera on tripod, turn off any vibration control and try again. Just place an object in that same location and try and re-enact the same lighting conditions. Pinpoint your focus on the bird or object and see what happens. If the tripod does not help then its just bad lighting.

Another note: when you look at chaman's hummingbird, notice where the light is coming from. There is just enough light to highlight the bird and stem he is resting on. His white tuff provides the right amount contrast to achieve good focus. His ISO is up there so dont be afraid to raise it.

you do not say, so I will ask the obvious, was your car running? if so, that will cause vibration. if not, then set your gear up on a tripod and take similar photos at the same distance and compare sharpness, if you get well focused photos, then you are having camera shake, you may want a tech check to make sure your VR is working properly. if you do not get sharp photos from a tripod at 500mm, you may want to send the lens in for calibration.

Perhaps the Delete button is the best to do with this photo... the bird is really not there and the rest of the photo is with out story or message.
Looking at the EXIF, why the 1/750 seconds... yes at 500mm if hand held a fast lens is needed... is there a rule of thumb of 1/mm for speed? :idea:
I used Topaz deNoise and there was a lot of noise in this photo!
Used Detail and Clarity to up the pazazz of the photo... aaa at best it is not there... why keep it... it is a photo to disregard and move on.
If you want help then submit a photo from several lenses and at perhaps ISO 200 ....400 is very noisy on this camera... try a closer shot. A simple one at 1/250 should be great steady for hand held.. even 1/125 is fine... try f 8 try a lower ISO and wider lens opening ... experiment a little ... you will answer your own question....

I am going to give you my take on this. The majority of focus problems are operator's error.
It seems to me that your focus was more on the front bolt of that steel structure than on the bird if that was what you were trying to do.
I am going to say that a shutter speed of 1/750sec. should be marginally adequate to stop motion using VR but still I prefer a tripod and shutter cable release with such lenses.
I downloaded the picture and immediately noticed it was badly underexposed. After a Level Adjustment I saw improvement and then I sharpened the image and although not needle sharp it was acceptable.
Keep also in mind that with such long lenses technique has to be impeccable. Depth of field also plays a part and all of that has to be taken into consideration and be properly planned before beginning to photograph subjects such as this one.
If you have a tripod use it. Be more careful when you focus, use good technique and I bet your pictures are going to be needle sharp.

On close inspection of the image itself there is a focus issue. The bolt head at the upper right hand side of the image though soft it is sharper than the bolts nearest the bird. It looks to me like compounded errors. the lens was in focus a few feet in front of the subject and there was sufficient movement / vibration to further blur the image. Exposure would also subtract from the quality of the image but focus was the primary issue to my eye. Best of luck, I hope that bird visits you again. What is it???

Especially on the right hand side of the picture, I see blurring that I interpret as camera shake. For the length of the lens, I would think you'd need a solid tripod.

I see you are shooting at a SS of 750, remember SS controls Ambient light. That is where I would look first
