The Kirk LS-2 Lens Support is a quick release lens support designed to be used with the Nikon 200-500mm f/5.6E ED VR or Sony FE 70-200mm f/4 G OSS lenses. When using the LS-2 on the Nikon lens, it must be paired with the NC-200-500 lens collar. When using it with the Sony lens it must be paired with the SRC-70-200-4 lens collar.
The LS-2 stabilizes the lens and reduces shifting when you loosen the lens collar to rotate the camera. It is machined from 6061 TG aluminum and has stainless steel bearings and bolts.
