I am attaching a few motorsport photo taken with my D7100 last month. They are horizonal, so it would not be qualified for the D7100 book. Unforunately almost all of my collection for motorsport is horizontal. Anyhow, it is mainly for sharing, as I did not see any posting so far for the motorsports catagory.
Photo 1 and 2 : D7100 with 300mm F2.8 Photo 3 and 4 : D7100 with 70-200mm F2.8
