HolyManta VND lens adapters with variable ND filters are out and being delivered to those that got in early on their crowdfunding campaign as well as online buyers via their store.
The HolyMantra VND adapters are available in two flavours; HolyManta VND EF | MFT & HolyManta VND EF | NEX, and are available to the general public on the HolyMantra website.
