Canon 600D has a
18.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic 4 processor. On the other hand, Fujifilm X-E2 has a
16.0MP APS-C (23.6 x 15.6 mm ) sized CMOS X-TRANS II sensor and features EXR Processor II processor.
Below you can see the 600D and X-E2 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 600D and Fujifilm X-E2 Cameras
As seen above, Fujifilm X-E2 has a 1.1x Larger sensor area than Canon 600D. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Canon 600D
or the
Fujifilm X-E2 ,
including hyperfocal distance.
