The Fujifilm X-T1 is latest camera from fuji X-series mirrorless system and on the other hand the OMD E-M1 is flagship camera of digital OMD series, the basic and most common difference between these two camera is the size of the sensor, the Fujifilm X-T1 features a large APS-C size sensor and Olympus E-M1 have M4/3 Size sensor.
For more detailed specification take a look at the detailed specification comparison review below…
Sensor: Fujifilm X-T1 features a 16 megapixel X-Trans CMOS sensor, the X-Trans bespoke pixel array, the sensor is designed with a randomized pixel pattern that completely eliminate the need of an optical low-pass filter without moiré and aliasing problems.
Olumpus E-M1 Comes with a Four Third format sensor, the sensor is smaller and will not perform as X-T1 camera in-terms of noise and dynamic range.
ISO Range of X-T1 is one stop more than Olympus E-M1, so you will sure get less noise in X-T1 images.
AF system: Both autofocus system that employs both contrast- and phase-detection methods / Both sensor have built in phase AF points so you get fast Auto Focus speed during still and video shoot.
Shutter: The Olympus E-M1 have upper hand here since you get better shutter range and fast top continuous shooting speed compared to fujifilm X-T1.
Image Stabilization: The Olympus E-M1 have built in Image stabilization, it compensates for camera movements up to five shutter speed steps. The five axis work in vertical angle rotation, horizontal angle rotation, horizontal shift, vertical shift, and rolling camera shake movements.
Display:: The X-T1 features 3.0″ 1,040k-Dot Tilting LCD Monitor and on the other hand Olympus E-M1 3.0″ 1,037k-Dot Tilting LCD Touchscreen, so Olympus wins here.
Both camera features rugged body and built-in WiFi Connectivity.
Verdict: The Fujifilm X-T1 will give you bigger sensor, more ISO range, no optical low pass filter for super sharp images and better video mode, on the other hand the E-M1 will give you bit fast shutter speed and built-in 5 axis image stabilization.

The Olympus E-M1 does not have a low pass filter. The E-M5 had one but Olympus removed it for the newer model.
Photos from the X-T1 are softer, because Fuji RAW files are processed in camera. So, less noise, less detail. Micro four thirds files are a little noisy but they clean up nicely. The difference between APSC and micro four thirds is not that big anymore. For optimal image quality you have to switch to full frame. But then you lose the depth of field advantage (if that’s your thing).
