MAT BOX Prime Circle is an innovative project designed
for videomakers and filmmakers shooting with still-photo
and cine-mod lenses!
The MAT BOX system offers some features that other
matte-boxes cannot afford like a complete interface mounting
system for every still lens on the market and the innovative
Sliding Base that compensates the “focus breath”
or extreme zoom extensions when changing the lens focal.
The lens extension just pushes and pulls the MAT BOX and allows a smooth ride on the 15mm rods.
No frustration anymore to adjust the matte-box position
for every different shot! The MAT BOX follows the lens
extensions sliding on the smooth sliding base.
