Adapter with Sliding Plate Manfrotto 577

The Manfrotto 577 Adapter with Sliding Plate is a quick-release accessory designed for use with the 501PL camera plate (supplied with Manfrotto 501HDV, 503 and 519 video heads) and the dedicated 501PLONG accessory plate. Lightweight at 0.28 kg and finished in black, the adapter lets you remove the camera from a head without detaching it from the plate and mount it onto other supports quickly and securely. Supplied with both 1/4" and 3/8" camera screws to fit a wide range of cameras.

Advantages

The sliding quick-release mechanism simplifies changing supports and reduces handling time. Compatibility with standard 501PL plates and the 501PLONG accessory plate ensures interchangeability within Manfrotto systems. The included 1/4" and 3/8" screws offer flexibility for different camera thread sizes, while the compact 0.28 kg weight keeps the adapter portable for field use.

Suitable for

• Camera mounting and quick transfers between tripods, video heads, and other supports
• Photographers and videographers using Manfrotto 501PL-equipped heads (501HDV, 503, 519)
• On-location shoots where fast reconfiguration and light weight are important
