The CASTEL-M focusing rail is the latest in innovative technology from NOVOFLEX. Its stylish and unique design is aimed at photographers who frequently work at magnifications from 1:1 (life-size) to 5:1. The manual focusing rail is exceptional in its construction and specifically manufactured for the application of focus stacking in a series of progressive magnifications to a maximum of 5:1. The CASTEL-M bridges the gap between high-end electronic rails such as CASTEL MICRO and conventional rail design. Convenient rear mounted adjustment control allows ease of use when focusing or stacking.
