MANFROTTO 577 SLIDING QUICK RELEASE
The Manfrotto 577 Sliding Quick Release Plate Adapter gives you the freedom to remove the camera from the head without detaching it from the plate and put it on any other support. The plate is fitted with 1/4" and 3/8" camera screws.
The 577 is compatible with the 501PL camera plate (supplied with the 501HDV, 503HDV and 519 Video Heads) and the special 501PLONG accessory plate.
Manfrotto's range of quick release camera-to-head plates, plate assemblies, sliding plates and other adapters are designed for professional video applications and use with long lenses and sport optics.
