Hooking a V1 to a Letus Extreme
 

Are there any issues I should know about when attaching a Letus Extreme to a V1? I'll need a step ring as the Letus will have 77mm and the V1 is 62mm (I'm getting the Letus with the 77mm because a EX is in my forseable future!). I'm also getting the Zacuto rods and a matte box. I'll be using NIKON lenses.

Is anyone using the Letus Extreme with their V1? I did a search but couldn't tell if the V1 is used with the Letus much.
