Olympus 7-14mm f/2.8 lens - for video on Lumix cameras?

[luminescence]

Hi there, was wondering if anyone has used this lens on a GX80, GH3, 4 etc - for video? I have just played in a store with it on my GX80 body and it seems superb. (A bit more versatile than the Lumix 12 mm 1.4.) I was just wondering if there are any technical things to watch out for?

You need to check about ND filter solution, because this lens does not take normal filters.
