Canon 7D? The EXIF says Nikon D7100.

I've tried the 1.4x TC on my 300mm f/4 PF (making it an effective 420mm f/5.6) and older 300mm f/2.8 (420mm f/4) and found that I much preferred the focusing performance of the bare lens over the extended reach when paired with the TC. TC on a base f/5.6 lens can make the combination very situational. There are not enough sunny days in the PNW for me to keep a TC around.
I was excited about the 500mm PF, but the backorder list is long and Nikon (just like with the D850) did not account for demand in their first production release. I eventually cancelled my pre-order and purchased a used 500mm f/4 on a Black Friday sale instead.
After letting go of my Pentax K-3II, I did eventually find my way back with the K-1II. I've contemplated adding either 150-450 (I've used it in the past with my K-3II) or DA 300 to my K-1II. The IQ of the K-1ii is really remarkable. Not a replacement for my D500 in a wildlife role, but definitely a compliment.

Rode my bike out to the Columbia Slough with my D500 and 300mm. Snagged this Wood Duck in flight.

That calibration tool should work just fine. One suggestion: shift the ruler down so that the middle of the rule lines up with center point of one of those circle targets. The aim of this is that when you shoot, you can validate the following:
- if the number (on the ruler) directly inline with the target is the sharpest, then no adjustment is necessary
- if the number (on the ruler) directly inline with the target is blurry and a number above it is sharper, that would mean the lens/body combo has back focusing
- if the number (on the ruler) directly inline with the target is blurry and a number below it is sharper, that would mean the lens/body combo has front focusing
I would not use liveview. I would use your viewfinder and center point to target. I would also use your camera's Auto Focus as that is the mechanism you are trying to resolve, not the manual focus.
Review on screen to confirm front or rear focus, then take multiple shots at different AF adjustment points (remember the order in which these are performed). Review on screen to find the best value.

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.

Agreed.
f/5.6 to f/6.3 is plenty.
With a stationary subject like a perched Cormorant, I would still like to strive for a shutter speed that matches the effective focal length of the camera. If the exif is correct, 1/1000s would have been easy to achieve without any introduction of noise.
Also important to note that some AF systems struggle after f/8.

Thanks! Likewise on the Cormorants. They are very misunderstood in the Pacific Northwest. Unfairly blamed for the decrease in the salmon population when a large Army Corps of Engineer managed dam is the culprit.

Great shots! Out of curiosity are these images captured with your K1 in crop mode or are you cropping the full frame file in post?
