1. This tripod mount ring is specially designed for Sony FE 24-240mm f/3.5-6.3 OSS and other lenses. Compatible with Sigma lenses: 14-24mm F2.8 DG DN Art E-mount, 24-70mm F2.8 DG DN Art E-mount, 28-45mm F1.8 DG DN Art E-mount, 28-70mm F2.8 DG DN C E-mount, 85mm F1.4 DG DN Art E-mount, and 105mm F2.8 DG DN Macro E-mount. 2. The lens support is hollow and lightweight, with a stainless steel screw and a net weight of approximately 155g. Positioning is via a switch and bayonet. It cannot rotate. All corners are rounded and ground. The tripod ring has an inner diameter of approximately 61.5mm and a width of approximately 18mm. It has a 3M film inside to protect the lens from scratches. 3. To install, loosen the knob, align the lens convex point with the ring groove, and gently press down to lock it in place. The tripod ring can only be used horizontally, not vertically. The installation position is close to the bayonet, and does not support the camera cage. 4. The tripod mount ring features a 55mm long 39mm Arca-Swiss quick release plate, allowing it to be directly used with 39mm Arca-Swiss tripod heads and clamps. This makes it more practical than a lens ring without a quick release plate. It also features 1/4" and 3/8" screw holes and a stainless steel anti-slip screw for directly mounting the lens to a tripod. 5. The IS-S720FE lens collar can be combined with the IS-3950PRO clamp mount converter (sold separately) and used with Manfrotto 50-structure fluid heads and stabilizers.
