Not all digital cameras have rolling shutters. The CCD sensors used in many broadcast cameras use a global shutter.,(reply>), @Photonic Pizza It's just percentage, but instead of max being 100%, the max is 360°,(reply>), @Dysan27 The optics are the biggest factor in the added cost as CCD sensors are less sensitive than CMOS sensors mostly because of the benefit which results in rolling shutter being used namely that the rolling shutter allows the sensor to continue collecting light during the readout. CCD sensors need to be kept in complete darkness for the entire duration of the readout of every pixel thus less effective exposure time per frame and less sensitivity so you need a larger aperture and thus larger lenses etc to be able to deliver good performance over a range of different lighting scenarios.,(reply>), @Dysan27 actually there are far cheaper options, like Black Magic Production Camera 4k that offer global shutter<br><br><br>there are also rolling shutter cameras that have very fast readout (&lt;10ms) like the sony a7 III  or the Canon 1DX II<br><br><br>the lenses for them don't cost as much as a cheap house too...,(reply>), Yup, and doing some quick googling the cost for a camera is several thousand to over $10,000  That doesn't even come close to the cost the broadcast lens which can cost over $200,000.,(reply>), @666Tomato666 Even today in digital cameras, especially professional ones like RED cameras, the metric of shutter angle is still used, a combination of shutter speed and framerate. This is a remnant from rotary shutters. A shutter angle of 90° means that the exposure time is a quarter of the time each frame represents (at 24 FPS, the standard in movies, that's about 40 milliseconds per frame, so 10 milliseconds of exposure time). This is because with a rotary shutter, 90° is a quarter of the disc, and the shutter disc makes one revolution every frame, therefore the film is exposed for only a quarter of the time of the frame. Film cameras and rotary shutters are used less and less of course, but shutter angle remains as standard terminology.
