Secure mounting – with precision-cut aluminium alloy construction
Board is cut precisely from a single aluminium plate to preserve flatness and maintain consistent flange distance under load.
Stable flange-to-film distance reduces focus shift and keeps lens alignment consistent during long shoots.

Black finishing on aluminium minimises stray light and glare inside the lens path, helping preserve contrast.
