This lightweight, monocular reflex hood's unique design features a right angle viewer that rotates 360° to accommodate different camera heights. Look down through it during low camera setups & then just twist it to adjust for high setups. Because it is so compact & lightweight, you can leave it on the camera during film insertion & exposure so it's always ready for your next shot. It's also perfect for copystand applications. Mounts quickly to your ground glass back, locking securely in place with a single sliding lever. The 2.5X magnifier enhances both composing & focusing, while an optional Fresnel lens provides the brightest possible viewing over the entire image area. The soft rubber eyepiece also eliminates extraneous light, adds comfort during use & protects glasses from scratching.
