Did a track day this weekend with my car. I didnt get to shoot long since I was driving but here are some shoots I was able to get in between. I was trying to get panning down, tried a few combos to see what would to turn out best. I tried slower SS but than the cars would just come out really blurry. Most use 200 ISO bc I used high tone priority on the camera since it was a gloomy day. On the last two however the sun came out more. All shoot with the 55-250mm 4.0-5.6 IS. 1. Exposure: 0.013 sec (1/80) Aperture: f/7.1 Focal Length: 90 mm ISO Speed: 200 2. Exposure: 0.033 sec (1/30) Aperture: f/14.0 Focal Length: 74 mm ISO Speed: 200 3. Exposure: 0.04 sec (1/25) Aperture: f/14.0 Focal Length: 90 mm ISO Speed: 100 4. Exposure: 0.017 sec (1/60) Aperture: f/6.3 Focal Length: 116 mm ISO Speed: 200 Thanks for looking!
