Really Right Stuff LCF-19 Replacement Foot for Nikon AF-S 180-400 f/4E TC1.4 Lens

The LCF-19 Replacement Foot from Really Right Stuff is designed for the AF-S NIKKOR 180-400 f/4E TC1.4 lens and is compatible with most Arca-type clamps. The LCF-19 gives the lens a lower profile and a lower center of gravity than the one originally supplied with the lens. This provides for better balance and stability when attached to a tripod. To secure the lens foot into place on the collar, turn the built-in thumb-wheel locking knob counter-clockwise.
