* In electronic shutter shooting, shutter speeds of 1/10000 sec. or faster are only available in Tv or M mode(up to 1/8000 sec. in Fv, P, or Av mode).

* Adjustments by the camera when the shutter speed is set to 1/64000 or 1/32000 sec. in electronic shutter shooting may involve the aperture value or ISO speed in some shooting conditions, because exposure cannot be controlled in 1/3 or 1/2-stop increments.
* Maximum shutter speed is 1/8000 sec. in HDR mode or with focus bracketing or high-speed sync, or when set to maintain the same exposure when the aperture value changes.
