Fits as if it was from the OEM
The fit on my Sigma 120-300mm f2.8 and finish are top notch. It is lighter than original plus arca-swiss compatible without having to add another plate. Am now able to correctly balance the lens/camera combo correctly on my gimbal head. And the lens fits better into it lens case. Loosening the tripod collar to rotate the lens to vertical is easy with smooth, sure movement and secure locking once set to desired orientation. A good purchase, money well spent.

Sturdy!
Bigger and sturdier than the original collar.
