Really Right Stuff LCF-53 Lens Foot for Canon 400/500/600mm IS-II and EF 200-400mm f/4L IS 1.4x

Really Right Stuff LCF-53 is a precision replacement foot engineered for Canon 400/500/600mm IS-II and EF 200-400mm f/4L IS 1.4x lenses. Machined from robust aluminum, it swaps in for the factory foot to lower the lens’ center of gravity, improving balance and helping produce sharper images. The solid construction reduces vibration for clearer, more detailed photos at long focal lengths while delivering durable, dependable performance in demanding shooting conditions. For quick attachment to tripods and supports it includes a 1/4"-20 female mounting thread, and at just 4.4 oz (124.7g) the LCF-53 keeps added weight to a minimum so portability is preserved without sacrificing stability.
