Q1683

what are four thirds cameras

Four Thirds system

The size of the sensor is significantly smaller than for most DSLRs and this implies that lenses, especially telephoto lenses, can be smaller.

Q1683

what are four thirds cameras

Four Thirds system

For example, a Four Thirds lens with a 300 mm focal length would cover about the same angle of view as a 600 mm focal length lens for the 35 mm film standard, and is correspondingly more compact.

Q1683

what are four thirds cameras

Four Thirds system

Thus, the Four Thirds System has crop factor (focal length multiplier) of about 2, and while this enables longer focal length for greater magnification, it doesn't aid the manufacture of wide angle lenses.

Q1683

what are four thirds cameras

Four Thirds system

The image sensor format , generally intermediate between those of larger SLRs and smaller compact cameras , generally gives levels of cost, performance and convenience intermediate between those two classes.
