With a scale and tripod screw, this rail slider allows fine adjustments in front, back, left, and right directions, making it especially useful for achieving focus in macro photography. The camera can be moved forwards, backwards, left, and right for precise positioning. A built-in scale enables accurate distance measurement. The gimbal head is easy to use and can be mounted directly onto a tripod, providing stable support. It offers 10 cm of movement front to back and 10 cm side to side, allowing for smooth push-pull and lateral lens movements within a small range, ideal for mid-range, close-up, and macro shots. In macro photography, precise focus and positional adjustment are critical. This fine adjustment device allows parallel and depth control, making it a convenient accessory for detailed work. Constructed with PPS material, the slider is lightweight yet durable, designed to support medium-sized camera setups. The drive mechanism uses a spiral moving gear for smooth and stable fine-tuning during close-up and continuous shooting.
