KipperTie has a new LCminiND Electronic ND drop-in filter adapter that utilizes technology developed by LC-Tec. This will initially be available for Canon’s popular Drop-In Filter Mount Adapter EF-EOS R with Variable ND Filter and any third-party versions that can take the same size filters. KipperTie will also be making versions for other products going forward.

The LCminiND will be available to pre-order soon. There is currently no indication of pricing. This looks like a good solution if you are running EF glass with a RED Komodo, Komodo-X, etc.
Above you see KipperTie’s John Marchant talking about the LCminiND.

The LCminiND Electronic ND drop-in filter adapter just fits into the Canon Drop-In Filter Mount Adapter EF-EOS R with Variable ND Filter like Canon’s original VND filter.
There is a myriad of adapters on the market that utilize drop-in filters, and some of them utilize electronic variable ND. Cameras from Kinefinity and Z CAM, just to name a few, have had adapter mounts for quite some time that have electronic variable ND.

The new LCminiND offers an ND range from 0.6 to 2.1 stops and it allows you to have precise control over how much vND you want to introduce. The only issue with drop-in electronic variable ND filters is that you can’t have them set to 0 ND. This means you will need to take the filter out if you are working in lighting conditions where ND isn’t required.
How do you control it?

There is a button and a dial on the LCminiND that you can use to make adjustments to how much ND you are applying. These allow you to make pretty precise adjustments.

KipperTie will also have a Bluetooth app that you can use if you want to control it remotely.
How do you power it?
The LCminiND can run for around 24 hours via its built-in battery.
Build Quality

The casing for the LCminiND is made out of aircraft-grade aluminum.
Prototype

KipperTie is also working on a prototype Revolva-style cartridge where you will actually be able to move the LCminiND out altogether so you have a clear setting with no ND. This obviously will make the whole adapter drop-in filter mechanism a lot larger.
