Common Weaknesses of Olympus OM-D E-M10 II and Fujifilm X-T4

Olympus E-M10 II vs Fujifilm X-T4: Physical Specs and Body features Comparison

Size and weight is a big decision factor when you are trying to find the ideal camera for your needs. In this section, We are going to illustrate Olympus E-M10 II and Fujifilm X-T4 side-by-side from the front, back and top in their relative dimensions.

Below you can see the front view size comparison of Olympus E-M10 II and Fujifilm X-T4. Olympus E-M10 II is clearly the smaller of the two cameras. Its body is 15mm narrower, 10mm shorter and 17mm thinner than Fujifilm X-T4.

Here is the back view size comparison of Olympus E-M10 II and Fujifilm X-T4.

Now lets look at the top view comparison of Olympus E-M10 II and Fujifilm X-T4.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Olympus E-M10 II is significantly lighter (217g ) than the Fujifilm X-T4 which may become a big advantage especially on long walking trips.

Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since Fujifilm X-T4 has an APS-C sized sensor and Olympus E-M10 II has a smaller Four Thirds sensor, Olympus E-M10 II's lenses for a similar focal length and aperture will generally be lighter and smaller than the Fujifilm X-T4 lenses.

LCD Screen Size and Features

Olympus E-M10 II and Fujifilm X-T4's LCD screens has the same diagonal size of 3".

Both cameras feature Fully Articulating screens where you can change the angle of the screen to make it easier to shoot from waist or over the head levels. Fully articulating screens are also useful for taking Selfie shots and video.

Olympus E-M10 II vs Fujifilm X-T4: Sensor Comparison

Olympus E-M10 II has a 16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features TruePic VII processor. On the other hand, Fujifilm X-T4 has a 26.0MP APS-C (23.5 x 15.6 mm ) sized X-Trans CMOS 4 sensor .

Fujifilm X-T4's sensor provides 10MP more than Olympus E-M10 II's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely. On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.

One other difference between these two cameras that is worth mentioning is that Fujifilm X-T4's sensor doesn't have an anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moire occurring in certain scenes.

Below you can see the E-M10 II and X-T4 sensor size comparison.

As seen above, Fujifilm X-T4 has a 1.6x Larger sensor area than Olympus E-M10 II. 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.
