The Hasselblad, Leica and Phase One cameras offer leaf-shutter lenses, which may be an option for studio and landscape photographers. You pay a premium in weight and cost, but the vibration reduction and flash-synch speed they afford are critical. A focal-plane shutter consists of two curtains sliding across the sensor for a given amount of time. With a fast shutter speed, one of the curtains can block light during the exposure, which means the light of a strobe will be partially blocked. The curtains have relatively high mass, so their movement introduces vibration. 

A leaf shutter opens and closes like an iris without partially blocking light. For example, a Phase One focal-plane shutter synchs up to 1/125 second, while the corresponding leaf shutter synchs between 1/800 and 1/1,600 second, stopping most motion. The leaf shutter’s minimal vibration keeps a long exposure clean as well.
