E-1
What it is
How it works
The E-1 uses the Four Thirds system standard, employing a 4/3-inch image sensor that measures 17.3 by 13 millimeters, resulting in a 2x crop factor relative to 35mm film format.[1]
Applications
The E-1 was designed for professional photography applications, including studio, portrait, landscape, and editorial work, aided by its weather-sealed construction for outdoor use in challenging conditions.[1]
The E-1 is suited for applications requiring high image quality in a compact, durable DSLR body, and its Four Thirds system allows the use of compact telephoto lenses due to the 2x crop factor.[1]
