Where there is smoke, there may be drifting! Kinetic friction expert Ryan Litteral leaves a plume of smoke behind his high-powered Formula Drift car while painting new lines on the street.
When shooting a fast-moving subject at a relatively long shutter speed (for panning blur), the sharp image rate is typically low. Increasing the number of keepers is the Canon EOS 90D's fast 10 fps continuous shooting speed, a highly-welcomed upgrade from the 80D.
In this example, I was evaluating the 90D AF system's ability to select the desired focus point using Auto AF point selection (all 45 AF points active) and ability to select the correct focus distance with a fast-moving subject. The results were very good with the AF point switching nicely while I attempted to track the car in the viewfinder.
