Olympus OM-D E-M10 Mark III vs PEN E-PL7 Overview and Optics

The Olympus OM-D E-M10 Mark III and the Olympus PEN E-PL7 both receive a score of 57/100 for their optics, indicating that they have similar optical performance. They share common specifications, including 16 and 16.1 megapixels, CMOS sensor type, Micro Four Thirds sensor size, Micro 4/3 lens mount, and image stabilization.

The E-M10 Mark III has a slight edge in certain areas. It features a faster shooting speed of 8.6 frames per second compared to the E-PL7’s 8 frames per second. This difference allows the E-M10 Mark III to capture fast-moving subjects with more accuracy. Additionally, its TruePic VIII processor is an upgrade from the E-PL7’s TruePic VII, which contributes to better image processing and overall performance. The E-M10 Mark III also has a higher DXOMARK score for its sensor, at 73 compared to the E-PL7’s 72, indicating a marginally better image quality.

However, the E-PL7 does have a minor advantage in terms of megapixels, with 16.1 compared to the E-M10 Mark III’s 16. This difference, though minimal, means that the E-PL7 can capture slightly more detail in images.

Despite these minor differences, both cameras have comparable optical capabilities. The Olympus OM-D E-M10 Mark III excels in shooting speed, processing, and sensor performance, while the Olympus PEN E-PL7 offers a slight advantage in megapixels. Since both cameras score 57/100 in optics, potential buyers should consider other factors, such as price, design, and additional features, to determine which camera best fits their needs.
