Nice little toy! I got the camera out of hibernation yesterday for an An-124 which was I saw was heading our way en route to East Midlands but he ended up nearer to Bedford than Leighton Buzzard  |

Very nice set Daren. Campton is not an airfield I had heard of before.
One question: the last image is perfectly sharp on the nose, but the tail of the aircraft is blurred. I sometimes see this on some of my photos and am not sure why. The aperture is f11 so depth of field should not be a problem. It's not like that on the first image, which is taken from a single angle. Any thoughts as to why this happens?
As for overflights, a FedEx MD-11F came over the house yesterday bound for Stansted, on a long, straight in approach. The camera, however, was upstairs in its bag, too late to go and get it. :-(

For my five-pennorth (I come very cheap!), here's my best guess on the discrepancy on sharpness.
Because the focus has been on the nose, and we assume the AF has maintained this as the subject pans R to L, then, even with a good depth of field, the relatively slow shutter speed of 1/125 would possibly exaggerate the relative perspective movement of the tail, relative to the nose.
Just my best guess - it's all 3D, you see!

I imagine that the difference in focus might also be due to movement of part of the plane in a different axis to the direction of panning? E.g., if you are panning horizontally but the tail is actually just rising/falling vertically relative to the nose, that would give the same effect possibly, especially at slower shutter speeds?

Panning at slow shutter speeds is so hit and miss , in theory if you could pan perfectly keeping the plane perfectly still in the frame and the plane was flying in the perfect line with in the frame the plane would possibly be totally sharp but in my experience ( I might just be bad a panning ) it rarely happens
Its actually quite surprising how far planes even slow moving ones move while the shutter is open . An example of this is lets say a prop plane has a take off speed of 90mph if you take a photo of it on take off at 1/100th sec the plane will move approx 40cm while the shutter is open which I think is quite a lot really . No wonder so many of my shots are blurry :-)

Your slow speed panning is much better than mine! I tried a a monopod but didn't seem to make a lot of difference for me - maybe need to persevere with it - as and when the opportunity arises again 😣
