HoodLoupe3.0 adjusts focus just like a binocular eye piece... you turn the eye piece in or out to set for your vision. Minimal magnification is used to eliminate visual pixelization of your image. Each HoodLoupe3.0 is encased in a user friendly rubber for comfort and protection from bumps that will occur throughout your shoot. Comfortable lanyard and compact protective storage case included.

Fits up to 3.0 inch LCD screens.
