Product Description

Upgrade your Canon EF 300mm f/2.8L IS II lens with this replacement foot from Hejnar Photo. This replacement is designed to offer improved balance and a highly secure connection to your tripod or gimbal head.

The double-dovetail profile serves as an invaluable asset, giving you a reliable secondary clamping surface on the top side of the rail to attach heavy-duty flash brackets or secondary accessories. Safety is a priority: the rail is equipped with two M3 safety stop screws to ensure your gear stays on the track even if the clamp is accidentally loosened.

The design leaves enough room for your fingers under the lens to freely use the lens focusing ring and allows the lens hood to be reversed for storage.

Installation Instructions:
To remove your original factory foot, use the M3 hex key tool that comes with the H122 to completely remove the four Canon mounting screws. To install the H122-Long, use the four original Canon screws and secure the foot to the lens collar. For long-term security in rugged outdoor conditions, consider applying a drop of Loctite 242 removable threadlocker to the mounting screws.
