Olympus E-M10 II vs Pentax K-70 Detailed Size Comparison

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 (298g ) than the Pentax K-70 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 Pentax K-70 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 Pentax K-70 lenses.

Olympus E-M10 II vs Pentax K-70: 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, Pentax K-70 has a 24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features PRIME MII processor.

Pentax K-70's sensor provides 8MP 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.

Another difference between these two cameras is that Pentax K-70's sensor lacks 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 K-70 sensor size comparison.

Olympus E-M10 II vs Pentax K-70 Sensor Size Comparison


As seen above, Pentax K-70 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.
