If it is compounded of multiple parts cemented together, each of these parts is considered an element, the whole is called a group. Bridge or superzoom cameras are an intermediate step between a compact and a reflex. To me, the problem is with the word "lens"--I think it would be much clearer if it said "optical path" as it entails more than just light-bending elements.

Mirrorless camera vs. mid-range DSLR how to decide? Retinas, film, and imaging sensor chips all have one other thing in common. Once the industry figured out how to manufacture a mirror that could swing up out of the way during exposure, the second lens could be eliminated, taking with it the parallax and extra weight and bulk that TLRs required. Since most EVF are much lower in resolution than the sensor, it is hard to judge best focus by sight, requiring the use of focusing aids like peaking or focus magnification.

The advantage of using a reflex viewfinder is that a better impression of the framing, focus and depth-of-field can be gained. The second relates to how they process colour. The negative part, they are bulky and there is not that possible option to opt for other types of focal points depending on which photos you want to take. Cross-section view of SLR system: 1: Front-mount lens (four-element Tessar design) 2: Reflex mirror at 45-degree angle 3: Focal plane shutter 4: Film or sensor 5: Focusing screen 6: Condenser lens 7: Optical glass pentaprism (or pentamirror) 8: Eyepiece (can have diopter correction ability) For more information on camera options, see Choosing a Camera.
