I have been using the Sigma 150-500, and decided to upgrade to the 600mm. I also purchased a 1.4 teleconverter. My shots have been blurry, and trying to figure how to properly set both the lens and the camera. From reading previous posts, it would seem that I should use a single focus point on my D800 instead of the 3D tracking...right? Also what should I set the various switches to on the lens itself? Tripod or normal? Which of the three settings for the AF would you start with? I want to learn the basics of this beast before I even think about using memory focus points, etc.
Oh, I am shooting primarily Eagles, as well as some songbirds with this lens.
Thanks for your input!!

First we need to diagnose the problem. Are your shots blurry due to camera movement because you are having problems hand holding the 600mm lens? Or are you having focus problems?

This is the type of problem that is almost impossible to diagnose without seeing an example image or two, and more details of your support set-up and camera settings.

Some images would definitely help.
The 600 f/4 focuses pretty quickly, but works better if you can track and follow the subject.
Extremely long distances may still be soft. The lens performs better inside 150 yards. Test on closer subjects - inside 50 yards.
Keep the teleconverter off until you get sharp images. It will soften images slightly.
Make sure you use a fast shutter speed and have good light to truly assess performance. Shutter speed needs to be 1/1000 or faster.
Increasing ISO may not be enough on overcast days. You need some light to see contrast detail in the subject.
Single point AF is good for stationary subjects. You might want 9 point for flying subjects. I use AF-C with both.
3D tracking should generally be turned off.
Tripod is for locked down images. Normal would be typical.
VR can be turned off if you are shooting at 1/1000 or more. I have seen some benefit at 1/640.
Stay away from fine tuning until you have gotten comfortable with everything else.
