The Panasonic Lumix DMC-GX8 takes the lead in our comparison with a score of 63/100, while the Olympus OM-D E-M1 scores 59/100. Both cameras are mirrorless and were released in the mid-2010s, with the E-M1 in 2013 and the GX8 in 2015. They share similar dimensions, with the E-M1 measuring 130 x 94 x 63mm and the GX8 at 133 x 78 x 63mm.

The winning GX8 is not only lighter at 487g compared to the E-M1’s 497g, but it also has a lower launch price of $1200 against the E-M1’s $1399. However, the E-M1 stands out with its slightly more compact size, particularly in height. Ultimately, the Panasonic Lumix DMC-GX8’s higher score reflects its better overall performance and affordability, while the Olympus OM-D E-M1 offers a more compact design for those prioritizing portability.

Olympus OM-D E-M1 vs Panasonic Lumix DMC-GX8 Overview and Optics

The Panasonic Lumix DMC-GX8 emerges as the winner in the optics comparison with a score of 65/100, while the Olympus OM-D E-M1 trails behind at 58/100. Both cameras have several similarities, such as their 10 fps shooting speed, CMOS sensor type, Micro Four Thirds sensor size, Micro 4/3 lens mount, and image stabilization. These common features provide users with a solid foundation for capturing high-quality images.

The Lumix DMC-GX8 outperforms the OM-D E-M1 in two key areas: megapixels and the DXOMARK score. With 20.3 megapixels, the GX8 offers higher image resolution than the E-M1’s 16.3 megapixels, allowing for better detail and larger prints. Furthermore, the GX8’s sensor receives a DXOMARK score of 75, surpassing the E-M1’s score of 73. This indicates that the GX8’s sensor provides better overall image quality and low-light performance.

On the other hand, the Olympus OM-D E-M1 holds its own with its TruePic VII processor. While the GX8 is equipped with the Venus Engine processor, the E-M1’s TruePic VII processor is known for its fast performance and excellent image quality. This could potentially make the E-M1 a more responsive camera, despite having a lower overall optics score.

Taking these factors into account, the Panasonic Lumix DMC-GX8 proves to be the superior camera in terms of optics. Its higher megapixel count and better DXOMARK score contribute to its higher ranking. However, the Olympus OM-D E-M1’s TruePic VII processor should not be overlooked, as it may provide a faster and more responsive shooting experience. Ultimately, photographers should consider their specific needs when choosing between these two cameras.

Olympus OM-D E-M1 vs Panasonic Lumix DMC-GX8 Video Performance

The Panasonic Lumix DMC-GX8 outperforms the Olympus OM-D E-M1 in video capabilities, with a score of 70/100 compared to the E-M1’s 57/100. Both cameras share some common features such as the built-in time-lapse functionality, which allows users to create stunning time-lapse videos without requiring additional equipment or software.

The Lumix DMC-GX8 surpasses the E-M1 in terms of video resolution and dimensions. The GX8 boasts a 4K resolution, with video dimensions of 3840 x 2160, providing users with superior video quality and detail. This high resolution allows for more flexibility in post-production, as users can crop and reframe their footage without losing quality. However, the GX8’s maximum video frame rate is 25fps, which is slightly lower than the E-M1’s 30fps.

On the other hand, the Olympus OM-D E-M1 offers a maximum video resolution of Full HD (1920 x 1080). While this is lower than the GX8’s 4K resolution, it still provides good video quality for most users. The E-M1’s advantage lies in its higher maximum video frame rate of 30fps, which can result in smoother motion in videos, especially when capturing fast-moving subjects.

Taking these factors into account, the Panasonic Lumix DMC-GX8 is the superior choice for users who prioritize video quality and resolution, while the Olympus OM-D E-M1 may be more suitable for those who need a higher frame rate for smoother motion capture.
