Nothing super special here as far as airplane shots go as I was just out testing out my new 70-200 2.8L IS II on a Skywest CRJ-700. I had ver I prior to this so I was curious to see how big a difference there would be. Renting a 2x TC III this weekend so I'll try and find some airplanes to shoot with that combo too and post up the results if I do.
This last one is a 100% crop with only a little bit of USM.
