Hybrid Technologies

Camera makers continuously seek to optimize shutter performance. Some innovative designs incorporate elements of different technologies. For example, some mirrorless cameras use an electronic first curtain and a mechanical second curtain for a hybrid EFCS design. Others may utilize a global electronic shutter during short exposure times and employ a different technology for longer durations. Hybrid shutters attempt to find the right balance of speed, cost, and image quality.

Shutter Image Sensor Evolution

Advancements in Shutter Image Sensors have closely paralleled improvements in image sensor design. As sensors capable of capturing higher resolution and more frames per second came to market, Shutters needed to keep pace. Early digital cameras with resolutions under 10 megapixels and frame rates of a few frames per second relied on basic mechanical shutters. But more pixel-dense sensors demanded faster, more precise shutters.

Current state-of-the-art sensors with resolutions surpassing 40 megapixels shoot at speeds approaching 20 frames per second, requiring very fast electronic controls. Global and advanced hybrid electronic shutters have become necessary to eliminate distortion at such high speeds and resolutions. Leading full-frame mirrorless cameras now incorporate global shutter designs to cleanly capture fast action. Meanwhile, cropped sensor cameras suitable for sports and wildlife utilize electronic front curtain technology.

As on-sensor phase detection autofocus points and shooting speeds continue creeping higher, rolling shutter effects could potentially become more problematic. Camera companies will likely rely more heavily on global shutter designs. New hybrid technologies may also emerge, blending the accuracy and speed of electronic controls with minimal moving parts. Ultimately, the shutter will need to evolve continuously alongside image sensors, processing capabilities, and the needs of photographers.
