The focal plane shutter has been newly developed specifically for our mirrorless camera. While achieving a maximum shutter speed of 1/4000 sec. (1/16000 sec. when using electronic shutter), a flash synchronization speed of 1/125 sec. or less, and high performance and durability with a shutter endurance supporting up to 150,000 shots*, the camera also achieves low vibration and a quiet shutter noise.
