If you use a teleconverter, you should try to stop down the aperature a bit. Since Planes don't have a lot of detail you should get away with unsharp mask for sharpening. if you stop down too much you will suddenly start to see how dirty your SENSOR is, then lots of clean up to do. If you are at the beach, you would need 400-800 mm to
have a nice shot of the Osprey as it seems to be always a bit too far and with the sun blasting down, you only have small window for unhazy shots. When the big boy comes out, C17 ,A350 your focal length may become too long unless you want head shots. Having a TC also means you may have to raise Shutter Speed or get a blurry shot..
You should use RAW mode and also overexpose a bit "+0.3 to +0.7" so that shadows
have a bit of a chance to be recovered eg Cockpit, engine blades, undersides...
just make sure the highlights cannot blow.. I also stop down to F9-F10 so that
I control the amount of glare going into the sensor. I have D3s so I set Auto ISO
to limit the ISO to a max iso of my choice.
TC also allow you to have that extra reach to capture the pilot in the cockpit!
Make sure you bring a LINT FREE waist bag with you or other handy container
in case you need to quickly remove your TC!

My Lens is Nikon 600 MM manual focus, wanted to get the new tamron but too bad there
is no stock. Manual focus and tracking the planes was quite taxing!
