Here are three photos of my daughter during her last race. All are OOC jpgs. Taken with xpro2 and 18-135. I took well over 1500 photos over 3 days of racing and had close to 70% in focus. Not all were keepers though because of composition etc. I keep wanting the 50-140 but have a hard time justifying it for the few times a yr it would be used. This lens performs pretty well in these conditions. Don’t let blue skies fool you it was -18C.
