Well my first couple of posts were of individual shots, processed quickly as low res images. I'll post full res shots on this thread as I process them. This may take some time as I shot around 2,200 images over the day, 2,000 of which were taken during the 3 hours of flying. I consciously had to slow down as well, as I was running out of storage space after 1 1/2 hours! Action was pretty constant, which meant little to no down time to do a quick review and cull of shots on the camera's LCD to free up more space.
I was shooting with a rental lens as I very rarely need the focal lengths required for wildlife/sports/aviation photography. Initially I was going to go for a fast Nikon super telephoto prime lens, but due to the nature of the airshow I wanted a little more flexibility and opted for something a little different - the Sigma 150-600mm S. As there were individual aircraft as well as formations, having the flexibility of a zoom was useful, and having 600mm at the long end meant I was able to get shots that most others couldn't. 600mm, even wide open, was pretty impressive, and after a good workout I would definitely consider this lens if I was shooting more at this focal length. Bang for buck was pretty impressive, focus was accurate and pretty quick, and even at 600mm and wide open the results were good.
When shooting aircraft, shutter speed is a priority. With propeller engined aircraft, getting a little blur into the props gives the sense of motion and speed - too fast and the aircraft just looks as if it's not moving, too slow and you won't have a high proportion of keepers due to motion blur, however good your panning. On fast aircraft at Duxford they were passing at 300mph + at low altitude and I was standing very near the threshold of the active runway so they were quite close too. The fact that the lens is relatively slow (f5 to f6.3) isn't really an issue for props as you want to be shooting at around 1/500th as a max, and with +2/3 EV dialled in you're easily shooting at that speed with f8-f11 in fair light.
Weather on Saturday was good - unfortunately I went on Sunday! Low cloud base, occasional heavy showers, variable light (and background skies as the weather blew through), made for some challenging shooting. Crowds were on the north side of the runway, meaning shooting towards the sun (or the bright part of the cloud where the sun was, anyway!). My next visit will be on the other side of the airfield in the 'naughty field' which will give better light.
So onto some higher res shots - I'll post a few at a time, with some ground shots to break things up a little:
1. Bf109 G-4 - 320mm, 1/500th, f11, +2/3EV, ISO200
2. Corsair - 600mm, 1/400th, f11, +2/3EV, ISO200
3. Bristol Blenheim - 180mm, 1/500th, f5, +2/3EV, ISO200
4. B17 and P51 - 300mm, 1/500th, f10, +2/3EV ISO200
5. Spitfire MkIa - This aircraft flew with 19 Squadron at RAF Duxford in WWII and was shot down over France on 25th May 1940, making a wheels up landing on the beach. The wreck was discovered in 1986 and the aircraft was restored, making its first flight in 2014. So It's come home. Classic Spitfire lines with wheels retracting and a dark sky in the background. 400mm, 1/500th, f6.1, , +2/3EV ISO200
