With a scale and tripod screw, this rail slider allows for fine adjustments in front-back and left-right directions, making it especially useful for achieving precise focus in macro photography. The camera can be moved forwards, backwards, left, and right with accuracy. A built-in scale enables accurate measurement of movement. The gimbal is easy to use and can be mounted directly onto a tripod for stable operation. It offers 10 cm of travel distance front and back, and 10 cm left and right, allowing smooth push-pull and lateral lens movements within a small range. This facilitates precise focusing and elevation adjustments, which are essential in macro photography. Constructed with PPS material, the slider is lightweight yet durable enough to support medium-sized cameras. The design has been widely supported and affirmed by photographers for its functionality in fine distance adjustment. The drive mechanism uses a spiral moving gear system, ensuring stable and continuous fine-tuning during adjustments.
