What are the components of a SLR camera? What function do they have?

The materials copied upstairs are very old and basically out of date. First of all, the current SLR is electronic framing, and the reflector is basically not needed.

At present, the electronic integration of SLR cameras is very high, and the processing area in the fuselage is basically responsible for all the work.

Lens+body+shutter

Lens: the photosensitive original that is responsible for transmitting light to the fuselage. Now the lens is also responsible for anti-shake and pre-processing (enlargement, reduction,,,).

Body: photosensitive hardware and processor. Photosensitive hardware is responsible for converting light into electrical signals, and the processor is responsible for image processing and setting and coordination of various devices (shutter, aperture, etc.). . . )

Shutter: Needless to say, it is responsible for the exposure time. Now the shutter tends to be electronic, which is more accurate and controllable than the traditional mechanical shutter.

In short, the current SLR has been very simplified.
