Quick one for you Thomas Larang, an engineer from Uppsala in Sweden brings you the HolyManta VND (variable neutral density). Thomas is using crowdfunding to get the HolyMantra VND into your hands. If you like what you see then give him a holla.
Neutral density (ND) filters are needed on bright sunny days, especially when filming video for that special filmic look. External filters however are fiddly and time-consuming. The HolyManta VND (variable neutral density) solves this problem by integrating ND filters into Canon EF-NEX and Canon EF-m4/3 lens adapters. This also provides advantages for run-and-gun situations, dusty environments, and for just having a lot of fun shooting video.
