Understanding Olympus DSLRs (E-System, sometimes mistakenly called E-Series) involves understanding the unique Four Thirds (4/3) standard.

The Four Thirds Standard

Olympus (and 4/3 partners Panasonic and Samsung) have bet on a 2x crop image sensor standard that is about 60 percent the size of the 1.6x and 1.5x crop sensors used by Canon, Nikon, Sony and Pentax.

Olympus claims certain technical advantages over larger image sensors. Canon, Nikon and Sony not only disagree but have doubled-down with 1x full frame DSLRs that have an image sensor 3.6 times the size of a 4/3 sensor.
