EOS 7D Mark II: Movie Servo AF speed and lenses

The EOS 7D Mark II features the ability to adjust the AF Servo speed for tracking focus in Movie shooting. If you have made changes to this setting but find there is no difference in the Servo speed, check the lens you are using; this function is only enabled when using USM lenses marketed in 2009 or later, or when using the STM range of lenses. If you are not using a lens in one of these categories, the AF speed will be the same as the Standard setting.
