Last week, I had the opportunity to take my new Canon 5D Mark IV out to the airport to put it to the test doing some aviation photography. After receiving it the mail a few days before I only had the chance to take a few test shots of my dog, so I was really excited to try it out for real. I had to buy a new CF card (as I don’t think SD cards do the camera justice), but I was able to use my 70D’s spare batteries on the new Mark IV. Before heading out I slapped on the Canon EF 100-400mm telephoto lens that I’ve been using been using with my old 70D, and I was all good to go.
