Yes. They plan to support 49, 58, 67, 72 and 82mm.
Interesting. But is it 77mm only?
This might be a good alternative to a matte box with 4x4 filters where a matte box and a counter balance would add roughly extra 10 lbs.
Xume pro kit (4 adapters + 5 holders) around $160
Heliopan 77mm Vari ND filter: $300
77mm rubber hood: $3.50
A bunch of step-up rings: $20
3 * Canon 77mm lens caps: $6 (Canon lens caps are the cheapest)
Just an idea. I have neither Xume or Heliopan.
