The SLR Magic 35mm T1.4 MarkII Cine Lens with 52mm Variable NDII bundle provides you with a variable ND for further exposure control when capturing your footage. Advantages of a variable ND over a set of NDs include being able to make minute adjustments in increments of less than a 1/3rd of a stop as well as making quicker adjustments than having to swap out different filters.
The included 35mm lens covers Four Thirds-sized sensors, provides a wide aperture range to choose from and is meant to work with cameras that have an MFT mount. The lens's non-rotating front allows you to use a polariser or variable polariser while avoiding unwanted exposure shifts or polarising effect changes when focusing your lens.
