To achieve maximum compatibility with the vast choice and types of lenses, we offer different 'Connection Kits' for the CINEbox. These Connection Kits determine how the lens physically attaches to the CINEbox. This CINEbox bundle ships with the Hard Mount Connection Kit which makes a solid physical connection between the CINEbox and the front of the lens resulting in a very stable setup. The Hard Mount uses 'Interchangeable Donut Inserts' which change the diameter of the rear opening where to lens connects, maximising lens compatibility. The 80mm Donut Insert is designed to fit lenses with an 80mm front barrel (like many PL lenses) or lenses with our 'Lens Attachment Rings' installed. The 114mm Donut is designed to work with the Carl Zeiss Compact Prime CP.2 lens range. Please choose which donut size you require via the drop down list.

NOTE: The Hard Mount Connection kit is designed to be used with lenses that have a fixed front barrel. If the front barrel of the lens moves/rotates when racking focus, please look at the alternative 'Rubber Bellows Connection Kit'. The Rubber Bellows and is suitable for lenses that have the front barrel move or rotate when racking focus.
