NiSi Cinema 72mm アダプターリング C5マットボックス用

Threaded onto my 72mm lens without any wobble, and the lock is reassuringly firm—finally a matte box setup that doesn't feel like it'll twist loose mid-shot. The aluminum machining is clean, and for the price, it's exactly the piece I needed to make my C5 rig work with my favorite primes.

The aluminum build feels sturdy enough, but the ring doesn't screw on quite as smoothly as my other adaptors—still holds the matte box securely once it's on.

Screws onto my 72mm lenses without any play, and the matte box locks in place with a satisfying click. Only gripe is the ring adds a bit of extra length, but that’s expected with adaptors.
