Sony and Minolta cameras flash sync speed.
What is flash sync speed
A camera’s flash sync speed, often referred to as the “x-sync speed” is the fastest shutter speed at which the camera’s sensor or film is fully exposed when the flash fires. It represents the maximum shutter speed that can be used with an external flash unit while ensuring that the entire image is properly illuminated by the flash. Beyond this sync speed, part of the frame may be obstructed by the closing shutter curtain, resulting in an uneven or partially dark image. Many cameras have a sync speed typically around 1/200 to 1/250 seconds, but high-end models may offer faster sync speeds, while some older or specialized cameras might have slower ones.
Some cameras support flash with shutter speeds above the flash sync speed. This mode is refered often as High Speed Sync (HSS) and is not covered on this article.
Some of the listed cameras have In-body stabilization (IBIS). When IBIS is active some flashes and camera combinations required to lower the sync speed (example: lowering from 1/250 to 1/200 on the A99 II) to avoid catching the shutter blade on the picture.
