Distinguishing features
There are many types of cameras. Almost all of them can be classified according to the following features:
- 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.
Common camera types
Below is a table with common camera types and the features that distinguish them.
sensor | viewing system | rigidity | focusing system | lens | metering system | example | ||
nature | size | |||||||
SLR | any | reflex finder through the taking lens | usually rigid | manual reflex focusing or autofocus | usually interchangeable | any | ||
TLR | analog | any | reflex finder through a second lens | usually rigid | manual reflex focusing | usually fixed | manual exposure or no meter at all | |
point-and-shoot | any | up to 4.5×6cm | optical finder or LCD screen | rigid or swivelling | autofocus or fixed focusing | non interchangeable (fixed or zoom) | automatic exposure or no exposure control (single shutter speed) | |
rangefinder | any | external optical finder | rigid or folding | manual rangefinder focusing | fixed or interchangeable (no zoom) | any | ||
viewfinder | analog | any | external finder or ground glass back | rigid or telescopic | no focusing aid | usually fixed | any | |
folding | analog | any | external finder or ground glass back | folding | rangefinder, ground glass back or no focusing aid | fixed or interchangeable (no zoom) | any | |
subminiature | any | smaller than 18×24mm | any | any | any | any | any | |
view camera | any | ground glass back | bellows and rails | ground glass back | interchangeable | none | ||
pinhole camera | any | any | any | any | pinhole lens | none |
