• 1. In this set, by changing the screw holes used to install the replacement foot on the base plate, it can be moved parallel to adjust the lens’ center of gravity, making it more convenient and stable when mounting the lens on a tripod and using it with different camera bodies;
• 2. The transverse hole spacing of the base plate screws is approximately 18mm, the longitudinal hole spacing is approximately 22mm, the base plate sliding slot is approximately 93mm long, and the extension hole spacing for the external telephoto support plate is approximately 20mm;
• 3. Installation Tips: 01. The four screws on the lens should be tightened in two stages, alternating; do not fully tighten just one screw first, which would prevent the other screws from aligning with the holes.
• 4. 02. In the first stage, place the four screws halfway into the holes (this is key). In the second stage, tighten the four screws alternately in a diagonal pattern.
• 5. The quick release plate is Arca-swiss fit, can be used with Arca-Swiss fit tripod head and clamp directly;
