Custom size Adapter Ring

Custom-diameter adapter rings — enter the required internal and external diameter, and leave a note if needed. Custom adapter rings are stackable, and we can make specific changes as well. Compatible with 156 / 136 / 114 / 95mm Matte Box and the Diopter Adapter.

We suggest a max of 5 step-down rings for best practice. Maximum suggested step-down size for matte boxes:

• 156mm down to 114mm
• 136mm down to 95mm
• 114mm down to 64mm
• 95mm down to 50mm

Not all possible variations are published — if you need help combining your perfect kit, send us a message via the contact form and we'll help you out.

Compatible with 95 / 114 / 136 / 156mm Matte Box, Diopter Adapter, and Lomo 35mm Matte Box.

*Cooke SP3 adapters are 95mm to 82 or 64mm and are not compatible with additional step-down rings, due to the specific clamping-area design.
