Benro are coming out with drop-in e-ND (electronic ND filter kit)

Finally someone has done it

It has a nifty bluetooth controller with auto-AE as well.

Curious to see how nice it is to use, but no word on pricing yet.

Interesting product.  I couldn't see from the images how it is powered, but it looks like maybe it has a USB-C port on top, so maybe it's rechargeable that way.  

I always assumed that such a thing would sit between the camera and lens (like those adapters with drop-in filters) and could be powered by the mount, but obviously this couldn't do that.

If we assume its total range is ND3-64 then that makes it ~1.5-6 stops.  Not a bad range - I use a 1-5 stop vND when out and about and find it has enough range for most run-n-gun conditions.

I gather e-ND filters are much better than vNDs with colour accuracy and not messing with the image too much (e.g. with polarisation etc)?
