Lens Collar Base for Canon EF 500mm f/4L IS II USM, EF 300mm f/2.8L IS II USM

1. The tripod mount base can't be used individually, must be used with quick release plate, like iShoot QS-120 / QS-220, we recommend QS-120; if you've got either of the two quick release plates, can install them according to instructions in the photos;

2. Tripod mount base made of Aviation aluminum, CNC precisely machined, anodized surface, with stainless steel screws, 1/4" screw hole, the volume is about 4.5 x 4.5 x 4.3cm, net weight is about 70g; the data of the mounting holes are collected from Canon lens;

3. When used in combination with QS-120 and IS-TB01, it can greatly protect the connection of long lens and camera body, decompose external shocks to the camera bayonet, reduce the impact caused by vibration, increase shooting effect rapidly.
