This deluxe hood works effectively with most lenses with filter sizes up to 125mm. Its adjustable bellows offers flexible directional control and can remain placed into any position by its self-supporting bellows construction. Suspended from a 2 1/4" (56mm) rod, the rear end of the bellows slides in and out along the rod end to accomodate differently sized lenses. The hood mounts securely to your camera's lensboard frame and can be flipped up for easy lens setting and adjustments. For extra-long lenses, an additional 2" (52mm) extension rod is included. This hood also comes with a continuously adjustable filter slot for 75, 100 or 125mm framed filters and a metal front plate that holds four magnetic vignetters (included). Best of all, this entire system is all one piece — no assembly required!
