I wouldnt be able to make this without the new crop feature (airplanes video)

[kgv5]

Yesterday i took my 5d3 to the airfield to test the new crop feature. Correct framing and fluid live view are just essential to shoot fast moving objects. What a great new tool!!!
Almost everything was shot with 70-200 f2.8 IS II with 3x 1:1 crop at 1080p 25fps. Lens set at f8. No single damaged frame, just perfect.  I have to get canon 2x extender now to have 1200mm lens
