Jes when I look back over 35 years as a pro aerial shooter I can say that I have owned just about every top of the line Canon ever made. In fact I was still using 6x7 film until about 4 years ago for large images. I suppose I can count on one hand the number of times in one year that I really used the full res. that the camera could produce. How many times did I sell a 50x60 inch print. I then bought a Panasonic DCM-TZ10 pocket size camera, just for the convenience of having it in the car always. I then looked back over 25 books that I have published and I realised that all of those images could have been shot with this camera or in some cases a 550D with a 70/200. I still have a few exotic telephotos that I use with a 5D but it is rare. It is the photographer that makes the shot every time. In a full size aircraft all you need is a 550D and the right technique. Cameras get knocked about in aircraft, the cheaper the better as long as they can do the job. Two years ago I had a panorama that made it to the final six in the Photographer of the Year contest. The full image was 2 Gig. it was stitched together from a bunch of 550 D images shot in portrait with a 300 mm lens. In 99% of the clients who will say they only want the best, very few could actually tell the difference between a cheap 550D image and a D800 etc. If it makes you happy thats probably the only good reason to buy it.
