The base plate is CNC machined from 6061 aluminum and is designed to be a perfect fit for the camera. It protects the base of the camera from cracking and adds additional 1/4" and 3/8" mounting holes for tripods and other mounts.
Check the product listing to see the base plate mounted on the AF100.
Matte Box filter holder:
• The Matte Box is designed to use the Cokin Z-Pro 4x4 filter holder
which is available at many stores (B&H, etc.). To help keep costs
low for our customers we currently only offer the Matte Box without the
Cokin Z-Pro so you can purchase yourself at standard retail price if you
choose to use it. Approx $60. (See Picture)
• We also recommend Cokin's lens ring adapter. They offer them for most
lens sizes and the Matte Box is designed to fit perfectly with the
adapter to take up any space between the lens and Matte Box. (See
Picture)
