Is it possible to conduct a lens calibration test and share your results?
Typically, lens calibration is conducted by being a certain distance away from the calibration target: focal length * n (n is typically a value between 25-50). Since you have a 560mm, I would not expect for you to stand 90 feet away from a target. Instead, I would just choose a 'working' distance. I selected 40 feet when I calibrated my 500mm.
Some additional tips:
- lens on a tripod
- target must be well lit
- turn OFF image stabilization
- shoot at the widest aperture available (in your case, 5.6)
- shoot at a lower ISO (I would aim for 800 or lower)
- shoot with a shutter speed equal to or GREATER than the max focal length to mitigate shake and increase sharpness
- use single point focus
The printout target should be fine, but I would find an image that has a ruler positioned next to the center target. The ruler is used to show degrees of front or back focus.

Those were some of my favorite shots from February and March. Birding is near approaching addiction status.
