With a scale and tripod screw, this rail slider allows for precise front-to-back and left-to-right adjustments, making it especially useful for achieving accurate focus in macro photography. The camera can be moved forwards, backwards, left, and right for fine positioning. A measurement scale enables accurate distance adjustments. The slider is easy to use and can be mounted on any tripod, providing stable support. It offers 10 cm of travel front and 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. Precise focus and positional adjustment are critical in macro photography, making this fine-tuning device a convenient accessory for parallel and depth adjustments. Constructed with PPS material, it is lightweight yet durable enough to support medium-sized cameras, a feature appreciated by many photographers. The drive mechanism uses a spiral moving gear for smooth, stable, and continuous fine adjustments.
