First post - Tractor/truck pull, Westmoreland, PA County Fair. Working with a D500 after many years with a D90. WOW! Anyhow, these were taken with the D90 and either an 18-300 DX ED Nikon or a 50-500 DG OS HSM Sigma for the action shots. Please give me your feedback - good, bad or otherwise - composition, processing, etc. I am aware that sharpness is an issue but that should improve when I move the the D500 and am able to increase the ISO. Note that almost all of the action shots were taken after dark using only stadium lights. Thank you.
