It has an electronic viewfinder and it does not have a reflex mirror; so, it retains mechanical shutter. That is why comparing to DSLR, mirrorless cameras are smaller, lighter and quieter due to elimination of the moving mirror. When the shutter button is pressed, a door slides up to cover the image sensor. The door will then slide down, exposing the sensor to light. After that, another door slides up to cover the sensor again, which stops exposure, taking the picture. When the light passes through the lens of a mirrorless camera, it appears directly onto the image sensor, offering a live view which then displays on the rear LCD screen. This image preview allows you to adjust settings like exposure, brightness, saturation, and contrast before snapping your photo. Without the mirror mechanism inside the camera body, the camera is less prone to shaking, so image quality is clearer and more professional. Fewer moving parts inside the camera system also means less noise, making it the best camera for quiet and discreet shots. With better focusing capabilities and high shutter speeds, mirrorless models make it easier for photographers to snap photos at a faster rate.
