The new Kirk quick release lens support for Nikon 200-500mm f/5.6E ED VR, Sony 70-200 mm F4 G OSS FE, Sony FE 200-600mm f/5.6-6.3 G OSS lenses used in conjunction with the NC-200-500 and SRC-70-200-4 lens collars and LP-68 lens foot.
By using the LS-2 lens support, the shift up and down is totally reduced when loosening the lens collar to rotate the lens and stabilizes the front of the lens.
