Abstract
In an exemplary embodiment, an LCD screen hood is provided for use with digital cameras. The hood includes a hood tube that defines a light blocking sidewall having an open camera end and an opposite viewing end and enclosing a longitudinally extending viewpath therebetween. An eyepiece mounted on the viewing end includes an eyepiece lens for enlarging an image on an associated LCD screen disposed at the camera end of the hood tube. An eye cup is mounted on the eyepiece for shielding the eyepiece lens from ambient light. An objective tube fixed to the hood tube carries a three piece objective lens mounted between the eyepiece lens and the camera end of the hood tube. Magnification of the eyepiece lens varies as appropriate between 1× and 2.5×. Rotation of the eyepiece tube provides for diopter adjuxtment.
