Wimberley AP 604 for Canon 400 f/2.8 IS and Canon 600 f/4.0 IS

The Wimberley AP-604 replacement foot serves as an Arca-Swiss quick release plate, designed for Canon 400 mm f/2.8 IS (Models I and II) and 600 mm f/4.0 IS (Models I and II) telephoto lenses. This durable component replaces the factory tripod mounting foot on the lens collar, eliminating the need for additional quick release plates. Made from robust materials, it offers increased stiffness compared to the original equipment and effectively reduces deformation and vibrations during use. The flat design enhances handling on conventional tripod heads like ball heads while allowing for more compact storage. The AP-604 creates optimal geometry for use with Wimberley sidemount heads and Sidekick accessories, ensuring lenses achieve proper balance. Compatibility extends to Arca-Swiss quick release clamps from various manufacturers, including Wimberley, Kirk Enterprises, Really Right Stuff, Arca-Swiss, and Markins. This replacement foot measures approximately 10.2 cm in length and weighs around 180 grams, maintaining a streamlined profile that does not interfere with lens operation. The precise machining ensures a secure fit on the lens collar with a reliable connection to tripod systems. Professional photographers appreciate the enhanced stability and vibration reduction that contribute to sharper images during extended telephoto photography. The design focuses on practical functionality without compromising the native capabilities of the lens. Installation requires basic tools and follows straightforward procedures for replacing the original foot. The matte black finish minimizes reflections and seamlessly integrates into professional camera equipment. This accessory represents a specialized solution for photographers seeking improved tripod integration for their Canon super telephoto lenses.
