What is meant by a bright or dim viewfinder?
Very simply this refers to the amount of light reaching your eye when you look through the camera s viewfinder. High-end Canon cameras tend to have very bright and clear viewfinders. Cheaper Canon cameras tend to have dimmer viewfinders, almost as if a brightness knob has been turned down. Obviously bright viewfinders are better than dim ones, as they make it easier to see your scene for focussing and composing. Unfortunately, bright viewfinders also require large glass pentaprisms (see below). Canon s cheaper cameras have either smaller prisms or roof mirror systems.
