There are many types of cameras. Almost all of them can be classified according to the following features: efl* the sensor: nature (digital, 35mm film, 120 film, APS film, other rollfilm, cut film...) and size (24×36mm, 6×6cm...);

  • the viewing system (external finder, electronic finder, LCD screen, single lens reflex, twin lens reflex...);
  • the rigidity of the body (rigid, swivelling lens, telescopic tube, folding, monorail...);
  • the focusing system (autofocus, rangefinder focusing, manual reflex focusing, guess focusing, ground glass back...);
  • the lens attachment (interchangeable lens, non interchangeable zoom lens, fixed lens);
  • the metering system: metering sensor and metering modes (programmed, speed-priority, aperture-priority, manual).

The features that will most determine the aspect of the camera are the viewing system and the rigidity. Once they are known, the general shape of the body is usually quite predictable.

The size of the sensor matters for the size of the camera and for the end result, while its nature has an incidence on the internal construction: a film camera usually needs place for the supply and take up spools, except for the cameras using cut film or plate film.

The focusing system and metering system will mostly influence how you will use the camera, but has few impact on its shape.

Unusual combinations of these features have existed, for example folding TLRs, subminiature SLRs and so on. However not every combination does make sense. For example an subminiature folding autofocus TLR is not theoretically impossible, but unlikely to ever exist.
