In a live stream on their YouTube channel, KipperTie unveiled the LCminiND, a new electronic ND filter designed to fit into Canon’s RF to EF adapter drop-in filter slot and other adapters that use this type of drop-in filter slot. This new product aims to address the shortcomings of other variable ND filter solutions for the drop-in slot (like Canon’s own solution for their RF to EF adapter) while maintaining compatibility with existing equipment.
The LCminiND utilizes technology from LC-Tec in Sweden to create an electronic ND filter with precise control. The filter offers an ND range from .6 to 2.1 stops and runs for approximately 24 hours on a single charge of its internal battery.
How can electronic ND be controlled with KipperTie LCminiND?
Users can control the filter in several ways:
- Via physical buttons on the device that allow adjustments in fractions of a stop
- Through a fine-tune mode for “exceedingly small and repeatable adjustments.
- Via Bluetooth connectivity and a companion app that provides remote control and the ability to lock the interface
The filter is constructed using CNC-machined aircraft-grade aluminum with anodized metal surfaces for durability. The control wheel features a ball-bearing mechanism for smooth operation.

LC-Tec’s variable ND and diffusion technology, applied to products
CineD recognized LC-Tec’s revolutionary technology early on, and we interviewed them several times in the past – IBC 2023 was the first time they showed a concept for a 4×5.65″ EVND filter. We awarded them one of our coveted CineD Best-of-Show Awards (registrations for the upcoming CineD Best-of-Show Awards for NAB 2025 are now open for manufacturers!), and only half a year ago at IBC 2024, they shared a first look at a Metabones EF-E CINE eND Smart Adapter and a concept for a variable diffusion filter system which works using a similar principle – check out the video here in case you missed it.
The Secrets of Optics
Ever been confused by focal length? Lens breathing? How about crop factors? What is the “Cooke Look”? In this course you’ll learn the basics of lenses - what they do, how they do it and what types of lenses there are.
It’s great to see LC-Tec’s variable ND technology now being incorporated by further adapter manufacturers other than Metabones – this time, it’s KipperTie’s turn, and it looks like a well-thought-out product.
Color accuracy and calibration of the LCminiND
According to KipperTie, one of the significant advantages of the LCminiND is its color accuracy. Unlike some variable ND filters that introduce significant color shifts, the LCminiND maintains consistent color throughout its range.
The filter does introduce a slight magenta shift compared to a clear filter, which Marchant described as “minus 9” on the tint setting of a RED camera. However, this shift is easily correctable through white balance settings, either in-camera or post-production.
Each LCminiND is individually calibrated at the manufacturing level. LC-Tec characterizes every piece of glass, and KipperTie further refines this calibration by testing it on cameras to ensure precise values.
While the filter does use polarization as part of its LCD-based technology, Marchant claims this doesn’t introduce the problematic cross-pattern artifacts commonly seen with variable ND filters. The worst effect noted was a very slight color shift when rotating 90° while filming screens.
It’s fair to say that Sony’s electronic variable ND technology, which is used in their FX6, FX9 and BURANO cameras, is also based on polarization. However, even as a “heavy user” of many of those cameras, I’ve never come across an unwanted polarizing effect while filming.
Pricing and availability of KipperTie LCminiND
The LCminiND will be available for pre-order starting next week at a price point between £600-650 (approximately in the high $700 range). It will come packaged in a hard plastic case with a foam insert and USB charging cable.
Future development: motorized clear filter / electronic VND switching mount
KipperTie also revealed a prototype of a revolver-style cartridge that incorporates the same LC-Tec electronic ND technology. This cartridge will be compatible with existing RED DSMC2 cameras and will feature motorized or manual switching between a clear filter and the electronic ND. This product is still in development, with pricing expected to be higher than the LCminiND due to the additional hardware involved.
