The Kipper Tie Revolva system is the ultimate internal ND solution designed for RED DSMC and DSMC2 cameras. iData is supported. The quick change cartridges contain four full-spectrum IRNDs. Neutral Density values from clear, 0.3, 0.6, 0.9, 1.2, 1.5, 1.8 to 2.1. The filter wheel snaps magnetically between positions. Backfocus is compensated correctly by design, with clearance for a wide variety of lenses. PLEASE NOTE: Some older lenses, with very large PL mount depth, like the Cooke 18-100mm, will not work with this mount. Included is a tool to help gauge the PL mount depth.

I can also include the Wooden Camera Revolva Top Plate if needed.
