I had three of these lenses CLA'd, and they came back with test results that
showed 1/500th accurate to within 60n two of them, and 30n the other. The tech
apologized, noting that not many leaf shutters are within 10% at 1/500th. Since
6 0s what, 1/12th of a stop (12th root of two), I'm not complaining!
