Description
The ARRI LMB 4×5 Tilt and Flex Adapter is a flexible rubber donut for the LMB 4×5 matte box. It seals the gap between the lens and matte box, so less stray light enters from behind. In addition, one adapter expands to fit lenses from 62 to 143 mm in diameter.
When you need it
The adapter suits lenses with front elements that extend during focus or zoom. Because the rubber flexes, the lens can move without forcing the matte box. It also works with the LMB 4×5 swing-away tilt module, where the matte box needs to move relative to the lens.
Fitting and care
The adapter attaches to the matte box with its locking thumbscrews and should sit flush. Make sure it fits closely around the lens to keep the seal effective. However, keep sharp objects away from the rubber, because they can damage it.
Compatibility
ARRI lists the adapter for the LMB 4×5, with LMB-25, LMB-5 and LMB-15 compatibility as well. It doesn’t include a matte box. The LMB 4×5 15 mm LWS console can mount on either the top or bottom of the setup.
