Question: |
How do I attach a Vocas Mattebox to my lens? |
|
Answer: |
The Vocas Mattebox is designed as a clip-on Mattebox, which means the Mattebox fits on the front of your internal focus lens. The mattebox is mounted with a "Quick-Lock" system. However, it is always possible to use the extra support of the Mattebox support MBS-100.

Question: |
How does the mattebox fit on different lenses? |
|
Answer: |
We have designed the Matteboxes with an exchangeable insert adapter ring. This means that for each lens with a different front outside diameter you will need a different type of adapter ring (See
Mattebox accessories page).

|
Question: |
I have an older external focus lens (the front of the lens rotates when I focus). Can I still use the Vocas Matteboxes? |
|
Answer: |
Yes, the mattebox can be used on a 15 mm rail support. This means that the mattebox is attached to the camera body and not to the lens front. In addition to the standard Mattebox kit you will need the following extra accessories: A Barsadapter (to fit the mattebox to the 15 MM rail support) #0360-0001, and a standard 15 mm rail support. |
|
Question: |
The lens I have is not mentioned in the list on the Mattebox accessories page. Is there an insert adapter ring available for my lens? |
|
Answer: |
Yes, there is a possibility that one of the standard adapter rings fits also on your lens. Measure the front diameter of your lens and compare it to the list. If there still is no matching ring available we can make you a "custom made" insert adapter ring (max. 105 mm). Please mention the front outside diameter, the brand and type of the lens and if the lens is an internal or external focus lens.
