Trap focus is an autofocusing mode introduced by Yashica, where the photographer prefocuses the camera at a specific distance. The camera’s shutter is automatically triggered when the subject moves into this preselected focus point, capturing the moment with precision.
This feature is especially useful for action, wildlife, and sports photography, where timing is critical. By using trap focus, photographers can ensure sharp images of moving subjects without manually adjusting focus, allowing for accurate and consistent results in fast-paced shooting scenarios.
