ND filters are a pain to carry around when you only want to go out with your camera and tripod. Genustech has finally fixed that with an electronically controlled ND filter. Watch the video below to understand how incredible this is:
It’s been in development for two years and in the form we saw lets you adapt Canon EF lenses to Sony E-mount cameras. A dial on the adapter allows you to control the amount of ND filtration electronically. The controllable ND means you’re able to fine tune your exposure by adding or subtracting ND. This allows you shoot everything at a preset aperture and adjust your exposure just by using the neutral density.
