I used to photograph a lot of aircraft & aviation events, especially at Air Shows. This was a faux World War Mitsubishi Zero fighter modified from an WWII North American AT-6 Trainer to look like a Japanese Zero Fighter for Airshows. Image taken years ago with a Nikon D1x with an 80-400mm lens @ 400mm. The D1X had a 1.5X crop factor, so the FOV with the Nikon D1X is approximately like a 600mm lens. I am going through my backup hard drives to clear up storage space to remove unneeded images and to make room for more recent images instead of adding even more hard drives.
